"PC Sync" is disabled again in calendar after locked screen I sync my contacts and events over my pc with thunderbird on it.
My phone: HTC One S, Android 4.0.3 with HTC Sense 4.0 and using GO Launcher EX 2.87.

Problem is that after enabled the calender checkbox to show me "PC-Sync"-data in calendar-app it does always disable this again after screen was locked.

Any suggestions what is wrong here?

So, i have figured out myself what caused the problem, thanks anyway:

I tried uninstalling some apps i installed before and looks like "Business Calendar Free Beta" caused this problem. After i removed it, it works just fine and normal.
And i didn't liked it anyway and i think the standard app is good for me.


Move from Internal to External I am using an Motorola XT1022. I have moved the games and apps from the internal to SD card to free the internal memory, but still there are some moved apps files that are occupying the internal memory. So I can't install any other apps.

Can you tell me how to move that apps files to the SD card?

If they are the default apps that came along with device you can not move them to card nor uninstall them. Rooting is the only method to do so. Be careful rooting VOIDS warranty of the mobile. Use Clean Master app from Play Store to clear junk files in internal memory.


Google Voice missing from app drawer after upgrading to ICS I upgraded from 2.3 a few months ago, but didn't notice that Google Voice was missing from the  app drawer. The market lists the application as installed, but does not give me an option to open the app.

How do I get it back?

If you to Settings --> Apps --> All, is it in the list of applications?  If so, click on it, click Uninstall, and then try to reinstall it from the market.

It's also possible that the market is incorrectly showing it as installed.  If this is the case, try going to Settings --> Apps --> All --> Market, click Force Stop, then Clear data.  The open the market again and see if Google Voice is still listed as installed, and if not, install it.


why does my android show -67 on my email icon? On the home screen, my Samsung Galaxy, it shows -67 over the email icon. What is this indicating and more importantly, how can I get rid of it?

It's buggy.  You should be able to fix it by clearing the data for the email app and/or any related apps (sometimes there's an "Email Storage" app and so on).


launch/start an App (Activity) by a gesture on the homescreen is it possible in Android(>= 3.0) to launch/start an App (Activity) by a gesture on the homescreen. For example: if the user swipes from the bottom to the top on his homescreen, then App XY should be started.

Thank you

You can install a third-party homescreen (launcher) app which supports gestures. Some examples: Holo Launcher HD, Apex Launcher, Nova Launcher. Note that such gestures will work only when the launcher is active (i.e., they are not global gestures accessible from any app), and may be eaten by scrollable widgets if they are present at the homescreen, and you start the gesture inside such widget.

Globally accessible gestures are possible too (e.g., there are apps such as SwipePad), however, this will increase resource consumption, because such app must be running all the time and listening for touch events, and also may conflict with other apps.


How can I remotely send commands to Tasker or other automation? I'm looking for a way of sending remote commands to Tasker on my Android TV. Specifically, I'm trying to find a way to trigger an HTTP GET request from IFTTT to Tasker or another automation app (like Automate) which would execute a command locally on the TV.

Is there any way to do this in Tasker, Automate or another automation app?

The best app I've found to send a remote command from one android device to another is going to be AutoRemote, a tasker plug in, but this assumes you android tv devices has access to the play store. This app should also work well for you if you have tasker because you can directly integrate it into IFTTT. By integrating directly with IFTTT it removes the issues you'll likely have trying to use an http get request.


Galaxy Y gps chipset model I'm trying to find the manufacturer /  model of gps chipset used in my galaxy Y.

Can anyone help me?

Broadcom didn't specify it, it could be any from this list, search for the GPS category. Galaxy Y uses the Broadcom BCM21553 which is ARM11. Based on this, I conclude it uses the BCM4751 GPS module.

You can also try this USSD codes that might reveal some information.


Can't change the language when phone screen locked I am using Samsung Galaxy Core. I have given Password to my mobile in English. Today for some reason I changed my Language to TAMIL and forgot to change back to English. My Phone got locked when i try to give the password the keyboard appears in Tamil and I can't do anything. How can I change it

Press the space button and hold the English language, and other languages will appear. Choose the language as you like and it will change the language.


enable phone module on Galaxy Tab A I have a Galaxy Tab A running an intercom app. Problem is that this app uses telephone's default ringtone. To change it, i would need to change telephone's ringtone. Now, this tablet doesn't have the telehpone module enabled. Is there a way I can enable it so that i can access all OS telephone options (like ringtones)?

As long as your Tab A is not a carrier variant (e.g. AT&T), you can just root the device and replace its default ringtone.

T280 is relatively scarce on development, but nevertheless here are threads (1, 2) dedicated to it and its LTE cousin (T285) on XDA-Developers. This post inside holds TWRP recovery for T280 for rooting and/or replacing. Since I don't have the device on hand, it's up to you to read through the thread, especially the ones after that post, to see how to flash and the precautions (it looks like the steps are more complicated than just flashing it in Odin).

For your purpose you don't actually need root - if you know what the corresponding ringtone file is, just use TWRP's built-in file manager to do the replacement. However, if you don't, it's advised to root so as to make things easier (previewing ringtone files on the fly).

The ringtone file should be somewhere under /system/media/audio. Although modifying audio files shouldn't pose risk, it's still strongly suggested that you make a full backup in TWRP before proceeding.


Custom Marshmallow ROM - encryption fails without error I have a Galaxy S6 G920F phone. I've replaced the stock firmware with a custom ROM - XtreStoLite. Attempts to encrypt the phone using Android's built-in FDE fail with symptoms similar to the ones described in this other question, but none of the solutions suggested there help in my case.
What I've tried:

disable Wi-Fi
remove the SIM card
hold the phone so that the screen switches to landscape mode
factory reset, also tried to encrypt right after the first boot after installing the ROM
plugged in to both a PC USB port and a wall charger
instal every single additional package supplied by the author in the Aroma Addons Package

None of this helped; the phone simply displays a padlock icon on black background for around 3-4 seconds, shuts down, and after 15 seconds boots normally without reporting any errors. The storage is obviously not encrypted.
What is the reason for this behavior? How can I encrypt my phone?

I figured it out - the solution is to perform a factory reset on a clean system right after installation. After this, encryption works normally.


Google Drive stuck uploading files Three days ago I was uploading 6 files to a Google Drive shared folder. It's not the first time I do that, but surely this time was different because not only the files weren't uploaded but also since then I have this notification

To fix it, I tried to

Click cancel.
Restart the phone.
Force stop the app in settings.

yet none of these options worked.

In order to solve it, I've uninstalled the app and installed it back again. That solved the problem


Can't access photos on Nexus device I have connected my phone (Nexus) to my windows 10 computer. I have entered the pin number on the phone and the driver for the phone is installed on the computer. The device shows up on Windows Explorer but the folder is empty so I can not access my photos. Any ideas?

On Android 6.0 and above you have to select USB connection type on your phone after you attached a computer or other device because the default USB connection type is charging.

You can do that when you plugged in your phone to your computer pull the phone's notification bar and tap on the appearing notification, something like this: USB for charging and select the desired USB connection type - in your case: File transfer (aka MTP).

There is a way to set the default USB connection type to MTP. You should enable Developer options on your device and in it search Select USB Configuration and set it to MTP.


Symbol LS2208 running on Android I try to use Symbol LS2208 (Barcode Scanner) with USB OTG on my Xperia Ray and nothing happen. I think my Xperia can use LS2208 because I using Logitect B100 (mouse) and work perfectly.

When I connect LS2208 into my Laptop with Windows 7 and UBuntu, LS2208 work perfect marked with beep.

Is there any driver for running LS2208 with Android?

If this device acts as a USB keyboard, then you don't need a special driver. Just be sure to set everything up before you start scanning: start an app that has some text input, and make sure you focus the text input field as if you're about to type in it.


How to disable data roaming notification? ('solved') Is there a way to disable data roaming notifications?

I get them every few minutes when I'm working abroad. And it happens on every acceptable roaming setting (off/national), international roaming setting is no option.

Also, long press > App info (Phone app) > uncheck 'Show notifications' doesn't solve anything.

Android: 4.4.4 & 5.0
Phones: Sony Xperia Z1 compact and Z3 compact (but was also a problem on my previous phone on Android 4.1)

Screenshot with notification (click image for larger variant)

Edit: This issue has solved itself as there's no extra charge anymore roaming within the EU.

This was a big annoying factor for me and I eventually solved it, but it requires Xposed (which needs root).

If you have root and Xposed, you can install XphonePlus to disable the data warning and modify the phone's notifications for calls, mobile data and many more.

Not sure if there is an alternative without rooting.


Always add youtube clips to watch later list I prefer to watch my youtube clips later on my computer rather then on my phone.
Currently if I encounter an interesting clip I want to add to my youtube 'watch later' list I have to:

* Open the link in youtube app
* Wait until youtube app has loaded
* Make sure the media volume is muted
* Wait until first buffering is done
* Stop playback
* Add the clip to 'Watch Later' list through the submenu
* Go back to the app I was using before I clicked the link

Is there a way to do this faster? Ideally all links normally opened in the youtube app should instead be added to the watch later list. Extra points if it doesn't disturb the flow in the original app so I continue reading.

I guess the easiest way is using an app like Pocket (formerly known as "Read it Later"). Pocket accepts input from all kind of apps via the "share" menu; I e.g. use it with my RSS reader, Twitter apps, Browser, and more. So far for the "Android end": Even before the buffer starts filling, press "Share", select "Pocket", done.

Now for your PC, Pocket offers addon for several browsers. For me, that's Firefox, and it's addon works like a charm: I've got a small icon next to my URL bar, which opens a (paged) list of saved entries which even offers a search/filter function – so it's easy to pick the wanted entry (here: Youtube URL) and watch the movie.

The "share process" on your Android device works in the background (gives you status information via "toast messages"), so it doesn't disturb you in whatever you're doing. As a side effect (you might already have taken that from my above description) you can do the same with a lot of other stuff you want to "consume later" – as long as it provides an URL: Tweets, web pages, RSS feeds, probably also Podcasts and more. And if you decide to check some of the stuff while on the road, Pocket offers a reader for that as well (included with the app).


Sending a group the same message and get individual replies First, I'm an android rookie.  I'm managing a softball team.  I need to be able to send 40+ phones the same message at the same time (SMS is fine), but get individual replies (each player/parent's reply should come to me but not go to the whole team).  I just switched from an iPhone 4 to a Galaxy S5.  iPhone app "Group Text!" was perfect - I'm having trouble finding something comparable for the S5/android. Advice?

Whatsapp broadcast list may help you, i'm not %100 percent sure but it says "you should use broadcast lists to message multiple people at once." and as long as it is not group the others dont see the individual replies (i think)


Lanix X110 (Mexican made, generic android 4.4.2 OS) Random "ghost" apps appear from nowhere and other issues I have some issues with my phone and I hope someone could help me
when I arrived home  just found in my phone some random apps with the "system" logo in them, like in this case those were named launcher

I stumbled across some apps like that in the past and I unistalled them but im scared that if I uninstall those my phone's OS gets corrupted

Because it had happened to me before but it was after getting an e-mail from a teacher and I coulnt recover even after doing a factory recovery so I sent it to warranty

Another issue I had in the past its that its way too slow, it takes a lot of time to just open google maps
Another one consist in not being able to detect any wi-fi network at all

The last issue I had (and the reason I had to root it) its some full screen and sometimes inapropiate ads that appeared in the lock screen, system settings, home screen, and other system apps

I hope you guys have some answers and suggestions on that
Regards

Do this. Those are brought to you by some app integrated to system. If you could be kin enough you could realize that even advertisements appear on status bar and or drawn over other normal apps. But though even if you haven't seen ads in your phone, automatic installation only is too worse an issue to live with.

Snatch Dr.Web antivirus from any source you're convenient with,
Install it and then run a full system scan.
Take note of Adware originated apps, binaries, and frameworks if possible. The app reports Google Play Services also as an adware but don't delete it.
Since you have kingroot, install a root file manager like Es File Explorer, or most preferably Solid Explorer and grant it root access.
Navigate to the reported files and delete them except Google Play Services.
Get back to kingroot and remove root access. Reboot your phone and you'll be good.

I did this on my Sony and all those things went away


stuck at "updating partition details" while installing magisk so I have a moto 4 plus running android 7 that I am having trouble with running twrp. I am following a guide to root it by unlocking the bootloader, flashing twrp (temporarily) and then flash Magisk-v16.0.zip. this is where I found this guide:

https://forum.xda-developers.com/moto-e4-plus/how-to/root-twrp-motorola-moto-e4-plus-xt1775-t3791064

I have one identical phone (I think they have identical build number) that I can do this without any problems. The other phone that I have problem with, twrp keeps getting stuck at "updating partition details." This happens when I try to do a back up so I have to skip it and try installing magisk.zip again and it got stuck again at "updating partition details." I am afraid if I try to turn it off now I may brick the phone.

I tried asking this at the forum where I got the instruction from but had no luck getting any answer. I am hoping to receive any guidance on this matter. Many thanks!

As u mention: if the "Updating partition details..." take more than 4 hours: You have a problem.

As it's noted on the XDA OP, have u flash the "no-verity-opt-encrypt.zip" file ? Apparently it's necessary to completly disabling the forced encryption on your phone.

Try to flash directly the Magisk uninstaller zip, reboot in TWRP, and try again to flash Magisk v16.


Looking for a launcher similar to Launchy, Synapse or Kupfer (with type to find and launch app feature) When using a normal computer I like to use a launcher to quickly launch applications and perform other tasks. Examples of such launchers are Quicksilver, Launchy, Gnome-Do and Kupfer (which I currently prefer). The power of these launchers is that you can easily open them with a shortcut, type a few characters to find the application and press enter to launch it.
I'm looking for a similar app for Android (I'm using a Nexus 7 with 4.2). I already found a few solutions, but they all have small shortcomings, so I'm still looking for the perfect solution:

Quickdroid: This Open Source app can search apps, contacts, music and a few other things. It also provides a 'quick launch' by adding a permanent notification to open Quickdroid. However it still feels as not fast enough, as you have to open the notification drawer, search for the quickdroid notification and touch it.
FAST App Search: This is a much simpler app (also Open Source), which only searches apps (no contacts etc, so that's it's weak point). It can however be configured to launch when dragging the home button from the bottom up to the center of the screen, thereby replacing Google Now.
Google Now: When dragging the home button up, the Nexus 7 will by default launch Google Now. This actually searches for apps, music, contacts etc and applications can add 'catalogs' to it. So in fact this is pretty much what I'm looking for. The problem here is that (1) After opening Google Now you need to tap the search field before you can start typing, (2) because of the google search suggestions, the actual matching applications are hidden behind the onscreen keyboard and (3) to really search all the 'catalogs' you need to tap 'search tablet'.
Google from homescreen: I can also press the google search button on the homescreen of the Nexus 7. The result is similar to opening Google Now, except that the search field immediately gets the cursor-focus. This obviously adds another step because you have to make the homescreen visible, and doesn't solve the search suggestions.

Is it possible to configure the 'drag the home button up'-action, to launch the google search, with the search field focused and immediately in tablet-search modus? This certainly feels like the best solution as it is already part of Android and apps can extend it by adding content.
Or are there other similar apps that can be configured to launch by a single tap/drag and search for apps, contacts, music, etc?

Have you not considered this application which actually overlays the existing launcher, and by using gestures such as tapping on the corner of the screen, to launch a certain app. The app is called SwipePad
Its a complement to the existing launchers out there on the market.
To quote:

SwipePad is a launcher panel overlay. With a single swipe action, you
can launch anything from within any app. It's extraordinarily simple
and intuitive to use:

Touch down a pre-set edge of the screen;
Move your finger towards the center of the screen so the pad will emerge;
Release your finger on a specific slot to action.


How do I wipe Nexus 4? I think I got virus and have no idea how to get rid of it.
Heyzap interstitial ads in every app

I think wiping phone will delete virus.

I have Nexus 4 with Android 4.3

Phone is not rooted but I am ready to root as I got virus without root.

PS I know about Factory Reset button

https://support.google.com/nexus/4/answer/2936226?hl=en
I am not sure if that is enough. I seen some ppl wipe phone from command line from PC. By uploading new firmware from PC. Is that different from Factory Reset button?
The reason is that I wish to delete virus that shows ads in Google Play, Desktop, etc

Factory Reset will delete all your data, and restore your phone as if it were brand new.

On the other hand, flashing a new ROM is one way to change another version (usually to a higher version or a custom ROM) of Android. In this case, data is retained, unless you do a full wipe, which is equivalent to a Factory Reset.

A Factory Reset is sufficient in your case.

Other questions:
What is hard reset and what is factory reset?


Catching real cause of android reboot I am currently using my phone with CM installed (newest release, clean install). For some reason the phone keeps rebooting at random moments, when sleeping (never when awake). I wonder if it is possible to find out the real reason of rebooting, other than checking /proc/last_kmsg: for me, it only states if it was caused by unsecure-watchdog-bite, or kernel panic. I am curious about finding out, which process' irresponsiveness caused the watchdog-bite, or what made the kernel panic.

Details:
Moto G xt1032, newest firmware
CM13.0, release ZNH5Y
recovery: twrp 3.0.2

Tl;dr: last kernel message is not informative enough about last restart reason.

Edit: link to kernel messages: https://1drv.ms/f/s!AqQWXVmn2ZoKonIJgnToo58XmoVy

You can try to use adb logcat command from the terminal/command prompt to examine continuously your device log. On your device has to be enabled USB debugging in Settings -> Developer options section.

Or after the random reboot try

su
cat /proc/last_kmsg > /mnt/sdcard/last_kmsg

from a terminal window on your device. You can download terminal app from Play.

For the su command your device has to be rooted.


App for calling a list of contacts, one after another My daily commute is rather long, and I make lots of phone calls while driving. Dialing while driving is illegal, so I have to stop by, dial, and drive again, which is inefficient, time consuming and unsafe.

Is there a way to create a list of contacts in advance, so that my Android will dial all the contacts on the list one after another?

While it doesn't dial automatically, you can add contacts to your home screen for one click dialing.

Home Screen > Menu > Add > Shortcuts > Direct Dial

Now choose a contact.

You'll now have an icon on your home screen that will dial with one click. Do that for all of your contacts and you can have a homescreen of contacts.


Allow USB debugging popup does not come in my new PC I am using a Nexus 10 Tablet( Android 4.4.4) . I have 3 PCs where I was already doing android development and one new PC on which I started today. All are windows 7 64-bit Service Pack1. The only difference is that of the 3 older PCs, one is DELL and two HP whereas the newer PC is lenovo ThinkCentre

On the PC which I got today, I am using the same android-sdk, same google_usb_driver(version 11.0.0) and the same platform tools(for adb--adb version 1.0.32), however in my newer PC, I am not able to go into adb shell. The difference I see is that in my newer PC , I do not get the popup asking "Allow USB debugging" and when I do "adb devices", it shows the device as unauthorized. Also when I do "adb shell", it gives the error message "This adb server's $ADB_VENDOR_KEYS is not set".

I went through various forums and tried the following: 1) Turning OFF and ON usb debugging and trying. 2) Doing "Revoke USB debugging authorizations". 3) Restarting my PC. 4) Deleting the C:\Users\UserName.android folder

However none of these worked. Also as I mentioned, it works absolutely fine on all the other PCs with the same device. This would indicate that something is missing/wrong in my newer PC. One thing I was wondering is that when the dialog to "Allow USB debugging" comes up, it mentions that "The computers RSA key fingerprint is:xyz". Could it be that my new PC does not have some openssl or something like that which is causing some issue? Also in my older PC, the .android folder has "adbkey" file, which is not present in the .android folder for the newer PC, could this in anyway lead to the problems or is it just a symptom of the problem and not the cause?

Also please note that in the newer PC, I can connect devices with android version below 4.2 (that is the devices with do not require authorization). Therefore as I said earlier, I think the root cause for the problem is that in my newer PC, I do not get the popup asking for authorization

I also got the same issue in my lenovo mobile. But when i deleted the .android folder in the home directory, my problem is solved.

For me the issue is the adb don't have enough permission to read the rsa key to communicate with the device. When we run adb server it'll create a folder named .android(Linux - /home/--username--/.android, Windows - C:/Users/--username--/.android) in the home directory of the current user which contains the private and public rsa keys used to communicate between the devices.

When I check the .android folder, it is assigned with root permission(I am using Ubuntu 16.04 and I don't know how its assigned). So when I try to run adb start-server it is trying to create .android folder. But the current folder with root access is not allowing this to create the adb keys. That's why its failed.

So I deleted the folder using below command. Use a particular method to delete the folder based on your operating system. Below I mentioned for linux.

  sudo rm -rf .android

Then restarted the adb server using below command.

  adb start-server

Now It created the .android folder and the rsa keys with the current user permission. Once done this I got the Allow USB debugging dialog in my mobile.

I know its too late. But I'm mentioning here because it'll help someone in the future.


QR code printer/reader? I run a small business repairing computers.  Sometimes I have very similar looking computers, and shenanigans ensue if the customer labels fall off or the serial numbers I record become detached from the computer in the course of repair.

Is there an app I can use to print a qr code of plain text information about a computer/client/problem?  I believe my current printer is equipped with bluetooth, but I wouldn't be appalled if I needed to purchase a specialized printer (zebra, or whatever).

Check out an app in the Play store called 'Barcode Generator / Reader'.

And here's a link on how to use it: LINK


Samsung Galaxy S I900 Bootloop in Recovery after flashing custom ROM My friend gave me his old rooted Galaxy S running android 4.0.x (or 4.1.x probably) asking me to restore its official ROM on it.

Context

Downloaded and installed Odin
Downloaded Galaxy S stock ROM
Downloaded and installed Samsung USB drivers
Removed SIM and MicroSD cards from phone
Cleared cache and data
Put the phone in download mode using the Vol down/up + Home + Power key and connected it to PC
Although the phone had "Download" option in it's "shut down popup" (The phone was already rooted and had some sort of recovery installed, CWM probably?) but Odin won't recognize the phone while in _that_ download mode.
Flashed the ROM having only "Auto Reboot" and "F. Reset time" options checked
It apparently went OK, phone rebooted a couple times and finally I could see the OS configuration screen

The problem

Right after I started configuring the phone, a "com.android.acore" (or similar) error appeared which I "force closed".
I restarted the phone (just for a fresh start in configuration)
After the phone started I got "com.android.phone" error which I force closed.
At this point I felt that something was wrong with the phone, so I turned the phone off with intentions of clearing the cache
Then I booted into recovery (Vol up/down + Home + Power), navigated to "wipe cache..." option and pressed OK, but noting would happen. No matter what key I pressed, it was not the "OK" key.

Now

The phone only starts in recovery mode, no matter if I press power button alone or any key combination
There is no key that performs the "OK" function in recovery mode
I cannot reflash the stock ROM because Odin requires the phone to be in download mode (but my phone only starts in recovery mode)
If i connect the phone (running in recovery mode) with my PC, windows displays two removable devices in "My Computer" which show "please insert disk.." error on double click

It is a kind of deadlock situation which I've been unable to resolve. I would like to get to the bottom of this issue

Questions

What is this problem called in android dev. circles? (soft bricked?)
How can I resolve the problem?
Are there ways other than Odin to flash a ROM on Samsung Galaxy S?

I've tried to search through xda and other famous android forums but all solutions to similar problems I could find require the phone to be in download mode.

Any help would be greatly appreciated.

P.S. I'm not a regular android rooting guy so I'm not versed in its jargon but I can read instructions and am waiting anxiously for help.

Step 7: Don't have auto-reboot checked. (unless it says otherwise somewhere that I'm not aware of)

Can you get into download mode with power + volume down ?

power + volume up should go to recovery and if there is no OS to boot it likely defaults to recovery.

If you can get into download mode, try finding a different compatible recovery like TWRP. I find it preferable to CWM personally. There is an ODIN flashable file: http://teamw.in/project/twrp2/117 (I'm not sure if this is the exact right recovery - definitely verify yourself) If you can provide additional model details, I can help narrow it down. The worst that will happen if it isn't the correct recovery is that flashing roms will not work and you will have to find a working one and reflash with ODIN.

The soft-bricked term applies to a wide range of conditions but yes this does fall under that category since you cannot actually use your device as intended.
There's several ways to resolve this problem. First try some of what I mentioned already.
You should be able to flash new roms with TWRP. In your state, I would highly advise trying it as you have nothing to lose. (I'm not a fan of Samsung/ODIN myself but have worked with them before. While I can personally confirm that backup/restore works in TWRP, I can only say I would be very surprised to hear that installing a custom rom does not. That is to say that TWRP absolutely should by all accounts work just fine for installing custom roms on Samsung devices yet I have not personally done this.)


How do I use VR on my HTC 816? I installed Cardboard, now what to do next?

Now buy google cardboard and build it. Place the phone inside and launch the app. This will allow you to get VR effect.


S3 LTE keeps rebooting I bet this problem has been posted many times but my galaxy S3 keeps rebooting the samsung logo over and over again. I've tried entering recovery mode but just when I'm about to select an option it reboots again...I thought it could be the power button so I opened up the phone to see if it's not being pressed down but it looked fine, I even removed the button to make sure(using a toothpick as a replacement button hehe).

So where could the problem be?!

Have you put any custom rom's on your phone?

Could be a bad one which is causing this

Either way your best option is to download stock rom for your device and flash it over via Odin


If I install an aftermarket "Always on Display" app, will it cause excessive battery drain? I am shopping for a new phone and it seems that my beloved notification LED has fallen out of favor, so I am willing to settle with Always on Display (AoD) as a second best.

I have been reading some and I understand that AoD is linked to AMOLED screens because in those you can "turn on" individual pixels, making it an energy draw small enough for it to be reasonable.

Now, I am browsing through GsmArena and I find that for AMOLED phones, some of them are qualified as having the AoD characteristic yet others do not show it.

Is it just because of some AMOLED phones being shipped without having the software option to use that feature (meaning that it could be added through third party software) or there are some hardware/firmware specs that make AoD unusable (either because it does not work or uses too much energy) if they are not present?

In short, I would like to know if I could add an AoD app to any AMOLED phone without expecting to suffer significant problems.

Yes but also no.

Basically, AoD is purely software. It does not require special hardware (you can even use it on an LCD screen, although it will use significantly more power and does not make much sense). This is why there are plenty apps available that let you keep your screen on.

At the same time I would also answer the question with no, because even though it is purely software, it's not just an "app". If you use one of those AoD apps, they will keep your device awake. All the time. This will use a lot more power compared to a device with AoD out of the box, which still allows the device to go to sleep while keeping the screen on, which saves a lot of energy.

However, depending on the device and how aggressive the power management is, you might not notice much of a difference. On my OnePlus 5, with fairly aggressive energy saving options, an aftermarket AoD app does not use a whole lot of power (about 1% to 2% of the daily power draw - comparable to a couple of minutes of surfing with Google Chrome).


Getting albums on home screen Now to go to albums I need to open camera, then click the last saved image, then click the photos icon, then click the albums icon. Can I just have the icon on my home scrern to go to albums instead? Also how about going to a specific album or even a specific photo (like a subway map or my family picture)?

Yes, you can. The "albums app" is usually called "Gallery" or "Photos", so just place an icon of it on your home screen.

Depending on launcher it may also be possible to add a shortcut to a particular image to your home screen. Also, as far as I know, ES File Explorer can do that too.


Incorrect caller ID details One of the contacts in my galaxy s3 shows a small "hd" next to her name for incoming phone calls.  When this person, who also has a galaxy s3 (not linked or connected to my phone that I know of), calls or texts someone, the caller id on the receiver's phone looks like the call is coming from my phone, not hers.  It's not clear whether this is happening with everyone she calls or just some people. This is so wierd I don't even know if the question makes sense.  Can anyone help?

HD is for sound quality and says that the contact person's phone supports HD sound, whereas the caller ID issue can be because of the error of contacts app or truecaller if it is installed.


Where can i find the HTC EVO native camera apk? A while back I put a Gingerbread [Deck] rom on my HTC EVO, and it came with another camera app (apparently the one that ships with the new Nexus S). While it does have some fun little features, I don't like it nearly as much as my original one, the main feature being spot focus on a touch to the screen. I have checked out third party camera apps, but none have quite done it for me. Does anyone know how I can get my stock camera app back?

Did you take a Nandroid backup or a Titanium backup before flashing? If you have a Titanium backup, you can try restoring the Camera app from there (app only, data can be incompatible). If you didn't backup with Titanium, you could do a new Nandroid backup, restore to the previous one, create the Titanium backup and then restore the new Nandroid backup. After this restore the app from the Titanium backup.

Since this is a system app I can't guarantee the compatibility of the app, but you can try and if it fails/is buggy, you can revert with Nandroid.


How to remove the picture next to my name in gmail here is my problem. I recently bought an samsung s4 Active. When I started using it I noticed that there was a random picture next to my name on all my outgoing emails from my phone. The picture is a random screen shot from a youtube video I uploaded years ago. I come to find out that google has taken it upon themselves to somehow link all my stuff together and now assign this picture as my "profile picture"

After some internet searching i find that I need to delete the album inside of Picasa that is labled "profile pictures" that i never created. That didnt work.

Now im told to create a google+ account and then turn around and delete it to remove this picure association. That didnt work either.

So my question is:
If I dont have a google+ account, have deleted any folder that is called "profile picture", and gone into my gmail settings to select "no picture"...what else do I need to do to remove this random picture that appears next to my name on all my outgoing emails from my phone???

The picture is linked to the google+ profile. When YouTube switched to g+ for comments, existing YouTube accounts were basically converted to a limited g+ profile. So, you may actually have more than one g+ profile.

Go to Google+ on the computer. Trust me it will be easier than the mobile site or the app. In the upper right corner, click on the picture or icon that is there. You should see the g+ profile you created and below it your YouTube profile.

If you are already on the profile with the picture, click on the "change photo" banner that appears over the profile photo.

If you aren't on the profile with the picture, click it to switch to that profile. Then click the picture in the upper right again and click the "change photo" ribbon over the picture.

Now you can change the photo to whatever you want or just upload a generic or even solid color picture. I don't know of a way to completely delete it, so maybe just upload an all white box instead.


How can I use a Chinese Samsung Galaxy Note 3 SM-N9008S in Iran? I bought a Samsung Galaxy Note 3 SM-N9008S in China. I can not install Google Play Services and there are only Chinese and Korean languages built in. I did not know Samsung manufacture mobiles according to region; I think this a disadvantage in Samsung product management.

I am living in Iran I would like to install Google Play Services, as well as add the Persian and English languages. How can I do this?

Sammobile only lists the Chinese ROM for your device, so it's unlikely you'll be able to use different languages with an official Samsung ROM: to get other languages and Google apps support, you'll need to use a third-party custom-rom. Similarly, it doesn't appear that the N9008S is an officially supported device for Cyanogenmod, likely because none of the developers have one.

There's a thread on the XDA Developers forum, but it doesn't make your prospects look good. Googling for cyanogenmod N9008S produces a lot of noise (rooting guides, and pages that mention N9008S but are actually about other devices), as well as one or two pages that might have unofficial ROMs but are in Chinese, so you'll have to trawl through them with Google Translate to see if any are actually helpful. You might find that as they're in Chinese, they've only ported a Chinese build of Cyanogenmod, which would leave you no better off.

In any case, you should be very wary of unofficial ROM builds, since they could backdoor your device or contain other malware, and you should be extra-careful about following flashing instructions in a language you don't understand. Only try something out if you're willing to risk bricking your phone.


How do I get the GPS icon to show in the status bar in CM7? Just did a fresh install of CM7 in my Incredible, it's fantastic, but whenever I turn on my GPS, it does not show in the status bar that it's on, like it does in the stock 2.2 OS.

Is there a way to enable this show it shows when it's active?

It will only show up if you open up an application that will use the GPS for something. For example just open up Google Maps. If you want to know if you left the GPS activated, just slide the notification panel and at the top you will have the toggle buttons, one of them is the GPS.


Android 4 slows down over year without reason I have LG-P760 with Android 4.0.4, not rooted.

I have about 500MB free space on phone and for last year I haven't really install much apps and so on. Despite that, my Android started to work slower, than slower and now it's ultra-slow.

I don't recall installing anything, using it extensively, mess with rooting or anything like that.

But even simple loading web browser or backing too home screen to see the pinned applications takes enormous amount of time now.

I've already tried clearing cache of applications and restarting phone several times during last month.

What may cause such behavior and how to get back to normal?
I know one year ago this phone with virtually the same set of applications and amount of stored pictures/music/etc. was capable of running very smoothly.
It looks almost as it was programmed to get slow after year ;)

Try a factory reset. After a while, things get gunked up with tons of unnecessary files that aren't always deleted and a lot of other stuff.

However, your phone will always slow down over time because apps become more demanding as technology progresses. There isn't much that can be done about this.


Android suddenly pops up ad Suddenly my Android always pops up this ad that always in that position, even sometimes a video ad, when I wake my phone from sleep. Anyone has idea?

When I open the recent used app, it displays the correct recent used app.

I have tried uninstall my but no luck:

  FF Record Keeper
  3rd party theme

I advice you to try and find which applications are running by using a program that displays your current processes. One of those will be the adware. You could also try and install some android anti-adware blocker, or even cut out the banner with an image editing program, make an image search and find which program or advertisiment the image matches, then you will know which program it is and you can find instructions how to remove it.

If you install termux you can run the command ps -al|more and paste the output, then we will see which processes are running.


TF300t bricked, no fastboot, wrong recovery I've been running CM11 on my Asus TF300t for a while now. A while ago, an (automatic) update broke my rom. From there on, matters have gotten worse. Right now, my tablet is a brick without an OS. Here's what I experience

No OS, tablet automatically boots into recovery.
Wrong recovery. Probably the Teamwin for the TF300Tg? It opens with 'Please enter password', and I can't access most of the features (E: Unable to find partition size for ... / E: Unable to mount ...). I've got a CM11 zip on my SD card, but I can't flash it. The recovery works, but most of the actions fail.
I cannot access FastBoot. If I press volume down + power, it just boots into recovery. Because of this, I can't flash the right recovery .blob.
A physical reset (with a paperclip) didn't change anything.

I'd be really grateful if anybody has anymore ideas / things I could try.

Thanks in advance

Autoupdates brick a lot of Transformers when on CM.  Bad sounding situation, in my opinion.  Fastboot and ADB are the only ways you could recover your device if you have a bad bootloader and recovery.  Have you tried holding Vol-Down while resetting with a paperclip?  That should force fastboot.  If not, we can try adb.

Do you have adb access while your tablet is plugged in to your computer?  Turn on your tablet so it is in recovery, and on your computer, run adb devices to see if your tablet is available. If so, adb -d reboot-bootloader should force your device to reboot into fastboot.  From there, run fastboot erase x where x is:

system
recovery
userdata
boot
misc
cache

and then after that, you can flash your files and/or restore your .blob files.


Better way to connect Galaxy Nexus (ICS) to Linux I can connect my Galaxy Nexus to my Kubuntu machine using the PTP protocol, but it's really slow.  I've read this interview about why Galaxy Nexus doesn't support USB Mass storage, and I've gone to http://www.android.com/filetransfer/ as instructed but there's no way I can see which will allow me to connect to the device using a linux machine and MTP.

Does anyone know how to get MTP, or any other protocol, working?

You could also try mtpfs or gMTP. mtpfs allows to mount the MTP device as a filesystem, while gMTP is a standalone program.

Over at AskUbuntu there's an answer that shows how to use mtpfs.


How can I find my phone when it's on silent/vibrate mode? Sometimes when I can't find my phone, I call it from my wife's phone or my landline. (There's also online service which provides a free call to your phone, it's a handy way to find a missing phone).

Unfortunately, it doesn't work very well if the phone is set to vibrate, and not at all if it's set to silent. Can I configure my phone to ignore the vibrate or silent setting and always ring for a specific number?

My old phone was a Blackberry, and it had a couple of features that made it obvious how to do this: 1) it had very flexible distinctive ring features, 2) it had a feature called "ringer profiles" that allowed users to create additional conditions where special distinctive ring conditions applied. (I mostly used its distinctive ring features to set an annoying person to always silent). Do we have anything similar on Android?

Alternatively, is there another good way to configure the phone to reveal itself even if it's set to silence? (Play music when it receives the word "sing" by text, for example.) If not as a native feature, are there apps that do this?

Finally, I know that nothing will work if the phone is out of charge, turned off, or set to airplane mode. The only solution there is "Don't misplace the phone when it's set to airplane mode."

If you have a Google account associated with the device, you can use Google Device Manager to send an alert to your phone.

  Sign in to your Google Account on android.com/devicemanager.
  If you have more than one device, click the arrow next to the device name to select a different device.
  Select any of the following options in the top left corner of the screen:

  Ring: Rings your device at full volume for 5 minutes - even if it's set to silent or vibrate.
  Lock: Locks your device with a new password.
  Erase: Permanently deletes all of your data.

You can also use the Device Manager Android app for this.

  Download and install the Android Device Manager app from the Google Play store on your device.
  Open the Device Manager app on your device.
  Sign in to your Google Account.
  If you have more than one device, click the arrow next to the device name to select a different device.
  Select any of the following options in the top left corner of the screen:

  Ring: Rings your device at full volume for 5 minutes - even if it's set to silent or vibrate.
  Lock: Locks your device with a new password.
  Erase: Permanently deletes all of your data.

Xperia Z3 DRM Restore I unlocked my Xperia Z3 without read risks (I'm in shame). Now I can't update phone with Sony Bridge, also read that I lost DRM licences.

So If some of my friends who has Z3 and still have bootlock, can take a TA partition backup for my device ? Can I restore this partition to my device ?

I couldn't update phone cause of bootlock. I relocked it and updates are working... But keys are gone forever.


What do the values in "Running Services" mean? When I go to following path

Settings : Applications : Running Services

I see:

Other: 78MB in 4

Avail: 109MB + 58MB in 8

What does above mean?

Specially, [78MB in 4], [109MB + 58MB] and [8]

As far as I know, it breaks down into this:

Other: This is RAM that is unavailable right now because it's in use by services that are actually running (it might be ones that can't be killed, in fact). Using your example, there's 78 MB of RAM in use by 4 processes, hence "78 in 4".
Avail: The first number here is the amount of RAM that is completely free and not allocated to any process (the 109 MB in your example). The second number is allocated but the process is in a state where it can be deallocated. Thus, "58 MB in 8" means there are 8 processes that are currently holding 58 MB of memory, but they are paused/frozen in the background and that 58 MB can be reclaimed by the OS if an active process needs it.

Edit: As Jake pointed out in the comment below, you can find a description in this entry on the Android Developers Blog (scroll all the way to the bottom).


Android tablet very laggy and freezing for 3 minutes (slow internal storage?) I have Pipo M9 Pro with Android 4.2.2

OS is quite laggy and to use Chrome is almost impossible... it is so very slow and sometimes I cannot do anything for 3-5 min because of freezing.

I made some tests with AndroBench and it looks like the internal storate is very slow.

Could this be the main and only problem? Also for the freezes?

Should I just get a fast SD card and link everything to there? With which app? How can I then take the card out and copy something to it?

From the specs about your tablet on       http://forum.xda-developers.com/wiki/PiPo_M9_Pro
They look good.

You should check how many apps that you have running at one time, too many apps running  can slow down your device. You should check how many apps you have installed, and check that your storage isn't completely full.

I also believe that you do have a slow internal storage on that device.

As far as linking everything to SD , there is a program called Link2sd in Google Play.
In order to use this , you will have to be rooted, as well as have a kernel that supports
mounting an external partition.

If you want to copy something to the card manually from a pc, you would need to find the microsd card slot , take out the micro sd and then plug it into a microsd to sd adapter, or a microsd to usb adapter. Then you will be able to transfer files.


Stop cursor from moving to end of word when touching text The default android behaviour when interacting with editable text seems to be to move the cursor to the end of the word you've touched, regardless of your touch location.

This is undesirable in many situations, e.g. if you have a stylus or a precise hand or a big screen and big text, or custom left and right arrows on your navigation bar, or a very long string without spaces.

Is there any way to prevent android from moving your cursor?

Future captain me here with an answer! Apparently this tap on word + cursor placement thing is not managed by the OS but by the keyboard app you use.

So here's a config that works great:

Use Swiftkey keyboard.

The problem is Swiftkey sucks big time:

it doesn't solve the question's problem, which is a crime against human competence.
it always inserts a space after a period, making urls or "e.g." impossible to write.
it doesn't let you capitalize the next letter after space only after pressing space after the dot, ie if you weren't writing a url.
you keep accidentally tapping on dot instead of space while typing quickly and you can't change the layout.

The following steps will de-suck Swiftkey and solve all your keyboard problems:

Root your device. Don't listen to your "parents". Best security is on rooted phones unless you're really unsavvy in which case it's just as bad as not rooting. (but for this you can unroot afterwards)

If you're concerned about Swiftkey privacy now you can install a firewall that blocks or monitors its internet access.

Install the Android Xposed Framework and Xposed Installer (may not work (yet) on the latest version(s) of android) (needs root, but you can unroot after the install if you must).
Download and install the "Exi for Swiftkey" Xposed module (github).

Just crawl through Exi's settings and you'll find the right checkboxes. It magically changes swiftkey's tap on words and other behaviours.

Where does Opera Mini save its "Saved pages"? When you save a web page in Opera Mini, it must be saved somewhere.

I want to know where can I find these pages, specific path or anything?

Users of Opera mini can Save web pages for later viewing, by Tapping the + button on the search bar to save a page.

Once pages is Saved, one can actually access the Saved pages from Opera mini browser app itself.

Once you Save web pages for offline viewing, these Saved pages are added to a Speed Dial group named Saved pages

This can be accessed by clicking on the Saved pages tab as shown in screen shot below.


Video-out solution for an analog input I just got a Galaxy Nexus and love it. My current debacle is trying to figure out how to hook up my phone the display in my car which only has analog inputs (composite.) That worked perfectly with my old Droid Incredible as it did video out with composite through the microusb port. So i've been looking around for a solution and have found two viable options:

Get a digital to analog converter box which is around $50 off amazon and I already have the TV out cable for the Galaxy Nexus which works fine.
Find a product like apple TV for android where I can push the video to screen through an independent device but I'm not about to install a wireless router in the car.

Right now I feel the only real option seems the converter box but that seems far to cumbersome of a solution for what I'm trying to do. Anyone have a better idea or cheaper idea?

I'm not sure about the Galaxy Nexus, but the older Galaxy models can output analog video through the headphone jack. The cable is similar to Nokia CA-75U. Since the phone is a Google reference model without Samsung's addons, I'm not sure if this works, but I'd say it's worth a try.


Toggle between dark and light theme in Google Maps Can we toggle between light and dark theme in Maps?
Maps has shown a message after a new update asking to choose between dark and light theme. After selection (dark, which was illegibly dark under daylight and especially sunlight, or maybe it's my presbyopia) the way to switch out of that without changing the whole system theme was to uninstall (downgrade) the app, update it and then chose the light theme when aforementioned message popped up again. My system theme is dark, and I want it that way, but I don't want dark for Maps, except maybe when it's really dark outside.
Maps 10.62.1
Android 10

You can change it from settings (to access settings, tap on the icon with user initial/user profile icon, next to microphone), then theme, wherein the same dialogue pops up, that you had initially to choose a theme.

Tested on Android 10 & 11, Maps version 10.62.1


Zenfone 2 Deluxe custom rom - question about model variants My phone went dead and a friend gave me his old Zenfone 2 Deluxe, which comes with the terrible ZenUI and a million asus apps that are a pain in the ass. I wanna throw it away and install a custom rom, something as clean as possible.

When googling, however, I find a lot of custom roms for Zenfone 2 laser, and for Zenfone 2 Z00A. According to Google, Zenfone 2 Deluxe is ZE551ML, however in the settings it says the model number is Z00AD. I'm very confused about this.

Of everything posted on xda's zenfone 2 forum, it's very hard for me to understand which roms I can install and which I can't\shouldn't. Please advise, how do I proceed?

ZE551ML, Z00A, Z00AD and Z00AD* (A/B/C) refers to the same device, as evident on ASUS' support page:

The custom ROM community would refer to this device as Z00A. Look for ROMs targeting this codename.

On a side note, the "Laser" variants have Qualcomm SoCs (SD410/SD615), vastly different from the regular/Deluxe variants.


Internal storage is used up by Android My Xperia J has 756 MB of internal storage. After 2 months of use I hardly can install anything as my system directory is 600 MB. It seems that in system/apps I have 200 MB of not used apk files (system apps that could be activated I guess), and 400 MB of the system with its core and its installed apps. So basically 756 MB is around 200 MB at the first instant of starting the using of my phone.

I use Clean Master to delete 10-20 MB of cached data now and then but as my phone is not rooted, I am stuck. I moved every application to the internal SD card (I can't use the external SD card - because it is not listed in the application settings as an option)

What can I do to install more apps?

Unfortunately this is a common problem for all xperia J users, including myself. I have installed many recommended apps for moving stuff from internal to external SD card but after doing this, pictures, music, videos etc I have moved cannot be played/viewed meaning you have to move them back in order for them to be viewed/ played again, however adter moving them back my files still didn't work. I have not yet come across the answer to solving this problem but I can recommend not downloading apps that move stuff to SD card as they won't work, just clear your cache as much as possible to relieve it of some memory. Hope this helps a little bit


How to "fetch v8" on Android phone? I have installed Termux on my phone(Android 7), then I installed git then git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git, then export PATH=$PATH:/data/data/com.termux/files/home/depot_tools But when I try fetch v8 it says:

bash: /data/data/com.termux/files/home/depot_tools/fetch: /usr/bin/env: bad interpreter: No such file or directory

There is no such thing as /usr/bin on Android. Those scripts are obviously intended to run on Linux/Unix systems – but Android uses a different directory structure (e.g. env can be found in /system/bin/env).

You could try adjusting those scripts – but it seems quite likely this will not be the only thing failing, so be prepared for having to adjust a lot …


How to put Google Store on Chinese Samsung Note10+ I'm currently living in China and decided to buy the Samsung Note10+ (has Android 9 installed) (had an iPhone from America beforehand), I did not know the headache that awaited me. I know no Chinese (Mandarin) and I can't keep asking my Chinese relatives for translations on my phone, so while I set the phone's system language to English, I still have no access to Google services at all.

I had tried installing Google Play store (ver. 17.5.16), Google Play Services (ver. 19.8.29), and Google Account Manager (ver. 6.0.1) from the AndroidAPKsBox site (used this site since apkmirror and other apk sites are blocked), all apks installed EXCEPT for Google Play Services which says the app did not install but with no error code. Is this the incorrect Services apk that I need?

Right now, VPNs are being blocked, even ExpressVPN so I'm not able to visit a lot of other helpful sites except this one. I know Google Play can't be fully utilized until the VPN starts working but I wanted to at least have all that I need on my phone so I can start using Google Play right away when available.

Edit: I just realized that there are a lot of differnt variants of Services that have different architecture and screen DPI. My Note has a Qualcomm so I assume I should choose the download that's made for ARMx64 chips with nodpi, correct?

I found a Google Play Services for Arm64 nodpi download here, I installed it along with my current Google Play store and Google profile manager and now I'm able to download Google Play store apps without issue. The biggest obstacle was getting the right Google Play Services download.

For anyone else in the same position, APK Mirror is a Godsend as long as you know which version you need (this article helped greatly) and make sure you download the compatible gapps.


How to fix sdcard empty under root with Kingoroot? My sdcard is empty when I use su. I have gained root using Kingoroot.
This answer shows the SuperSU solution (mount namespace separation).

How to mount an sdcard to su? What additional information should I provide to get help?

It's a MTK device with Android 4.4.

I never used Kingoroot, so can't be sure if it provides and option for master mount (su mm) or not. You can switch to Magisk or SuperSU once the device is rooted. If you can't or don't want to, you can use:

su -c 'nsenter -t 1 -m /system/bin/sh'

from commandline instead of simple su. This will make you switch to root mount namespace. For details see this answer.
nsenter is usually available as busybox applet.

Since mount namesapce was implemented in Android 6, this might not be the problem with your KK device.

PS:
If Kingoroot works for you, it indicates that your device has some serious security flaw(s). Do consider an upgrade.


Is it possible to view detailed GSM information on my Android phone? I'm trying to find such an app, but I can't, which leads me to suspect that it's not possible, either because of software or hardware limitations. What I'd like to see is a list of cell towers that my phone can reach (both from my carrier and other carriers); signal strengths from each; perhaps an option to lock on to a specific tower or forbid the use of some tower. And, generally, the more data available, the better. So - have I just missed the right app; is there no such thing out there (and I'm free to write the first one); or is such data simply unavailable and I can just give up?

There is this app called Antennas. It can't do everything you have asked for. But it can show you the tower you are connected to, the signal level, and other towers from you carrier that your phone can see/connect to and their signal level.

  Map the GSM/CDMA antennas in your neighborhood. This app monitors the
  GSM/CDMA cellular network connection; displays a map of approximate
  cellular antenna locations and their RF signal strength; and can log
  the data to a text or KML file.

  Does not work on Verizon 3G & CDMA Support is limited by Android, not by the application CDMA requires Eclair Works
  best with 2G GSM. 3G/CDMA support is very limited.


Does Samsung Galaxy S2 Plus supports Miracast? Since Android 4.2 there should be support vor Miracast. Also the Samsung Galaxy S2 Plus has Wifi Direct. But I can't find any option.

Does Samsung Galasy S2 Plus supports Miracast? If yes, where can I find the option in the menu?

No, I don't believe the SGS2 Plus supports Miracast.  This feature comparison shows the other phone having it but not the S2.

However, from my understanding, since Wi-Fi Direct is supported it shouldn't be extremely hard for someone to get Miracast working on the device.  This has been done for the regular SGS2, though I do not completely understand those posts.

Talk to Android Device via UDP via a wired connection I have an application that can be controlled via Open Sound Control, a UDP based protocol. Now this works fine via wifi but I NEED a wired connection because wifi will not be available to me later for this project.

I'm using a Galaxy Note 3. I tried to attach a Ethernet->USB adapter that worked on an Android TV stick but it doesn't seem to work with the Note 3 and pretty much any other android phone I tried.

Now is it possible to either get Ethernet working or use a standard USB connection to the Host PC? It doesn't have to be available in the whole LAN, just the PC connected to it via USB needs to be able to send OSC messages to the Note 3.

This was WAY simpler than I thought it was. I was trying to get this working for days now but it's actually really simple.
My first approach was using reverse tethering, having the idea that I would need the Android device to get its Internet/LAN connection from the PC and not the other way around.
Though that is not the case, just enable USB Tethering on your android device and thats all you need.

After you did that, open a terminal emulator window on the device or open an adb shell session with the command adb shell. Enter netcfg to print out all the IPs and look for a device named rndis0 or usb0 or maybe another name, depending on your ROM or device. Simply look at all the devices that are "UP" and make sure its not Wifi or Mobile data connection, you can recognize them by the device name.

If you think you found the correct adapter (it shouldn't show more than 2-3 devices that are listed as UP and have an valid IP next to it) simply send your OSC messages to that IP adress and it will work just fine. This should work with about any network protocol.

You should be able to access the device over another computer aswell by setting up some port forwarding on the host PC to the android device IP and sending your messages to the PCs IP. Or maybe using the Android IP adress works aswell though I somewhat doubt your Router is aware of the device.

Double check the IP if its not working, it will not be the same sub network as your LAN. I made that mistake with my first try and blindly entered the first 3 number blocks without having a closer look.

how to pass google play games data to another user My son is playing games on a tablet configured with my gmail. He is now old enough to get an account of his own. The only problem is that he plays a lot of games via google play games and I wouldn't like all his data to be deleted. Is there a way to transfer all the data to the new account?

No. google is going to be bringing a feature soon that lets you share your apps with up to 6 peoeple. besides that the only option is the illegal option which requires root and to know where the game data is and copy it from one device to another.


How to revert to android 7 on Xiaomi A1 phone The phone has some bugs in this new update I have tried doing a factory reset but it still has the android 8.

It applies the same concept as this video https://www.youtube.com/watch?v=06rlFAwGJYM

you will need to download the ROM of android 7 and flash the device

its an easy process that take less than 5 minutes


Moto G 1st gen getting "unfortunately google play services has stopped" message even in safe mode I hope you can help.
I have a Moto G 1st gen phone and for the last two days I have had the dreaded "Unfortunately google play services has stopped" message.
I cannot "force stop" the app as suggested elsewhere, since the only buttons still working are "disable" and "manage space".
The "force stop" and "uninstall updates" buttons are greyed out.
The "clear cache" button is not greyed out but doesn't do anything when pressed.
I have tried changing to "safe mode" and even then I still get the same "unfortunately...." message.  Apparently that means it isn't a problem with any of my many installed apps (?)
I cannot update the app manually as it doesn't exist on "play store".
I did have an incident yesterday where Norton closed down internet access for a time, having discovered "malware" in an app which I then had to delete to reinstate the internet connection and continue using the phone.  I can't remember if the play services message was appearing before that incident or not.
Please advise in straightforward terms what I can do next - is a factory reset my only option or could you suggest something else?  If you can suggest something else, please advise in simple terms what I need to do and where to find what I need, if you can.
The version of Google play services I have on my phone is
Version 9.4.52 and obviously it isn't running the latest operating system as there was never an upgrade available for my phone.
Thank you !

If I'm correct, the best way to handle this is usually this: Tediously, navigate to settings. Once in there, go to accounts and remove all your accounts. Once this is done, back out of that to the main settings. Then navigate to apps. Look for Google Play Services. Force stop it, then clear cache and data. Do the same with Google Play Store. Once this is done, go open up the Play Store. If done correctly, usually it'll ask you to accept the Terms of Service. If you get that, then you can sign in and it should be fixed. Sometimes you have to repeat this a couple times because sometimes it doesn't trigger whatever it is that fixes it.


Is it safe to use launchers? I am new to android OS.I recently purchased nexus 5 and came to know about several launchers.They are just mind blowing experience.But one of my friends suggested me not to use launchers as they override native os or something like that.

My question is that is it really safe to use launchers? I don't want to make any harm to phone OS or anything.

Does it clear all data and clean up everything when I uninstall it?

Kindly provide me knowledge of launchers and what are the disadvantages of using it.

Thanks

As with any app:  look at the permissions it requests and think about whether the app legitimately needs those permissions.  There's nothing inherently unsafe about using a custom launcher, but if it requests permissions that shouldn't be needed just to display a home screen, it may have hidden malicious functionality.  (Or it may use them for legitimate purposes:  for example, some popular launchers request permission to "directly call phone numbers" so that they can provide the ability to put direct-dial icons on your home screen.)

To see the permissions of an app you've already installed, go to Settings -> Apps, find the app, and scroll down to the bottom of its info page.  You can also see an app's permissions in the Play store before you install it:  scroll down to the bottom of the app's page in the Play store and tap on "Permission details".

Note that a launcher app will (naturally) know which other apps you launch with it.  That's generally not a problem, but if the launcher app has Internet permission, it could potentially send information about which apps you use to a third party, which would be a privacy violation.

When you uninstall an app, any data stored with the app itself is removed; this generally includes things like customization settings.  But if the app has "modify USB storage" permission, it may have also created files in your phone's shared storage area — the files you see when you plug the phone into your computer with a USB cable.  Those aren't deleted when you uninstall an app, but you can delete them yourself, either with a USB connection or a file-manager app on the phone itself.

A custom launcher doesn't "override the native OS" in any unsafe way.  It's really just a normal app that happens to respond to the phone's Home button.


Is it possible to modify files on sd from PC without unmounting? Motivation:

As I currently got started to put some media (music,ebook,etc..) I need to organize (add,modify,move,rename) files often but also see if the android apps are still recognizing my files properly.

As file transfer and organization is much faster on PC I plug in the USB cable and do what I want. Unfortunately android unmounts the sd memory so my apps e.g. Gallery wont be able to see the data. So I have to unmount on my PC and then nasty long media scanning takes places, and finally I can see the files within android. What me disturbs is the tedious mounting/unmounting process.

Question:

Can't I just simply alter files on sd memory over USB/Wifi or whatsoever while leaving the sd memory mounted? That would be awesome.

Ahh, I should have known, ssh is the solution. Therefore install an ssh server e.g. SSHDroid then you should usually have sftp and ssh to your phone. As command line tools like sed echo and basename are available even renaming is really easy :D.

The really great thing is you even don't need a wifi around, you can make your own with wifi thetering and SSHDroid will still work, though you have to disable the presence of a network in its options first.

You don't need to root the phone.


Bulk manage Google Contacts with dual SIM card I have a Archos NEON 45 with a dual sim option. Never had a use for it until my business phone stopped working. So I transferred the business SIM-card to my Archos NEON.
I also added by Google Business accounts in order to have the business contacts available on my phone. Now I have to choose which SIM-card to use when making a phone call.
There is the possibility to link a contact to a specific SIM-card. By now I have to edit all the business contacts manually to specify this link to the correct SIM Card. Is there a desktop app or Android app that can do this based on the groups I have specified in each contact?

Accidentally stumbled upon a useable solution. In the Settings menu on the top is a menu item 'Manage SIM". This is meant for setting up names and defaults for the SIM cards. At te very bottom there is a menu item 'Link contacts' (translated from the dutch 'Contact verbinden'.
Next step is to select the SIM card and then you can select contacts to link to the selected SIM card. (Don't forget to press the 'Add contact' icon at the top-right after selecting the correct contacts, instead of the checkmark at the top-left.......)


Network storage application I have android device eGreat U9 with attached external HDD. I'd like to use this device also as a NAS and mount it's drive as a network disk on my linux desktop. Here is what I've already tried:

SMB/CIFS server - transfer rates low and significant delay when mounted
SSHFS - even worse than the previous one (probably because of encryption overhead)
FTP - transfer rate over 8-10MB/s, so problem is not in my network at all, but when I tried to use ftp mount, it was really unusable

Is there any other way I can use it as a network storage? I tried more than one app for every solution above, but if you know about some certain application, that works for you, I would appreciate your advice.

On the device is rooted Android 4.2.

Maybe you could try webdav with apache, and davfs2 on the client side. This should be about the same speed as FTP.

NFS is also an option, if your kernel supports it. However, if you want some security (neither of these options has encryption (ok, webdav can run over http), but at least authentication), nfs authentication is pretty hard to set up compared to webdav.

If you want some real security, you can use SFTP/sshfs, and fiddle with the SFTP's encryption settings, namely the set the Ciphers and MACs options (you have to set these client-side). There is probably a combination that is significantly faster, and any is still much more secure than nothing.

And for any of these, I would use some chroot-ed linux with native code, e.g. debian (it's quite easy to install with Lil'debi).


Where does the movie downloaded from "Play Movies & TV" get stored in external SD card? I recently bought and downloaded a movie from "Play Movies & TV" application. It is not automatically detected by any other video player. So, where does the movie downloaded from "Play Movies & TV" get stored in external SD card?

I just bought and downloaded the 90 minute Google "AlphaGo" documentary movie in HD. It was about 2 GB in size.

It was saved on the SD card in this folder (I obscured the exact name with *):

  Android/data/com.google.android.videos/files/Movies/YXJh******NvbQ/ylEP****BE/

In that folder were 156 files with names like this made-up format:

  0.163253726153.23764387642386.v3.exo

Each *.v3.exo file was about 2-25 MB in size. There was also a single file called

  cached_content_index.exi

So I imagine the download was made into smaller chunks.

The "*.v3.exo" format is a YouTube format.


How could I view that Android Screen on a computer or larger screen How can I display my Android ICS Samsung Galxy S3 Screen on a Laptop or Monitor Screen? Are there any fast quick programs which do this?

There are lot of apps to do that. One is droid@screen; you need to have access to Android development toolkit for that though.

Extremely sorry for not providing the links, here are the links

droid@screen http://droid-at-screen.ribomation.com/ please install the USB drivers of you phone, instructions about how to use it is given there on the site.

If it asks for ADB you need to download Android SDK from here http://developer.android.com/sdk/index.html (Got to other platforms, download SDK. ) ADB will be present in platforms tools inside the SDK


Executing ADB commands while running scrcpy I am using the program scrcpy in order for me to control my Android phone from my PC.
It all works just fine with showing the Android screen, but I want to open an app from within the scrcpy console box.

I have not seen anything on Github about a feature like this - just the ability to add or remove an app.
Am I overlooking something?

You can open up a new command prompt window and issue whatever adb commands you want. They would work.
You can also put scrcpy in background if you want to use the same command prompt window to do something else there. Head over to Superuser to know more about this.


SD Maid on Rooted Roger's Galaxy S3 hanging on "System Cleanup" and "Duplicate" My phone is a rooted Canadian Samsung Galaxy S3 (SGH-I747M) running stock 4.4.2. I've had SD Maid installed for a very long time and it's worked great up until now. I've never had any issues with it. I hadn't used SD Maid in a couple of months due to carelessness so a couple of days ago I figured I'd give it a run.

Well, most of the scans to run as per usual but for some reason both "System Cleanup" and "Duplicate" seem to start but then shortly after hang and not complete. For example, I notice System Cleaner will start with a full 600 op/s but then it reaches the "cache" portion of the scan and then the op/s seem to drop steadily, all the way down to 5 op/s. I even let the phone sit for an hour or something, assuming for whatever reason, that the cache was massive but that doesn't seem to be the case. Shortly after, if you try to do anything, SD Maid crashes.

Something similar with the "Duplicate Finder" function happens as well. Start fast at around 120 op/s, gets to scan about 380-480 files and then the op/s drop to 2 op/s but the scanned files aren't moving at all.

I'm not sure if this is a bug with SD Maid, a problem with my phone or something else? I was curious about installing a older or beta version of SD Maid to see if that would help but I've been reluctant to do so. I've noticed my phone has also been somewhat more sluggish lately and that the battery has been dying much faster. I've been using Greenify for a year or 2 now and that always seemed to help. I added Hipmunk and Snapchat to the Greenify list a few days ago, thinking that they might be the culprits to the battery loss but it hasn't helped much.

How do I diagnose or fix SD Maid?

Do you have an external sdcard in your device? If so, remove it and try again.
When sdcards start throwing errors and have to remap sectors it kills their performance. As this is usually an indicator for a dying sdcard i would suggest to backup any important data you have on it.


Will the HTC Thunderbolt be able to use AT&T's network? I'm speaking from a hardware perspective. It supports the 850 and 1900 network bands that AT&T uses, but will it work? The phone is amazing, absolutely destroys the Inspire 4G (which is a complete joke in my opinion).

No.  It's a CDMA phone using 800 and 1900 mhz bands. CDMA phones can't be used on GSM networks (AT&T, Tmobile...). GSM and CDMA are completely different technologies.


Samsung Note 8 GT-N5110 restarts by itself My Note 8 (stock android 4.4.2) worked perfectly until one day it decided that it would restart by itself every time after I shut it down. To make a long story short, if I reset the device to the factory settings and leave the battery disconnected for a few days the table will work fine after reconnecting the battery. However, if I connect the device to the internet it updates untold thousands of applications and the problem reappears. I have repeated this process about four times and have concluded that there is an update that is causing the problem, but have no idea of how to identify the problem application(s). I have also decided that there are applications like Allshare Controlshare Service that will update themselves once they see the internet even if you tell the device not to update anything. They will also reinstall the update even if you roll it back to the factory default. I would appreciate any ideas on how to safely reconnect this tablet to the internet.

Following esQmo's suggestion, I followed the general instructions given at
Install Original Factory Rom on Samsung Galaxy Tab 2 10.1 and reinstalled the stock firmware. Never did anything like that before, but to my surprise it worked and the tablet now is behaving itself.


What are good Android headphones with Play/Pause and volume controls? I've had an iPod Touch for a while and am used  to controlling the music player without having to take the device from my pocket. I've had a look around for headphones that will work with the Samsung Galaxy S's TRRS connector and for players that would work with those headphones but haven't seen any combination that looks like it would work. Is this achievable? I'm also happy to consider alternatives like Bluetooth if that would work.

I've found a few Bluetooth headsets that would do this. for example the MOTOROKR S9:

  Works with any brand of Bluetooth®-enabled compatible phone or music device that supports Advanced Audio Distribution Profile (A2DP) and Audio Video Remote Control Profile (AVRCP).

However this is a bit offputting:

  For optimal outdoor performance, position music device in close proximity to and in line of sight with the S9's internal antenna, which is located in the base behind the user's head. Placement of the music device in a front pocket is not recommended.

So they'd be fine as long as I strap my phone to my back or hold the phone like the model in the photo on the linked page is. Hmm.

A few other Bluetooth headsets I've looked at include:

Motorola HT820 (a bit bulky, but does have a wired option)
Nokia BH-503 (my current favourite).

I would still prefer a wired solution if possible so will keep looking. I have found that the Samsung Galaxy's TRRS connector is Left-Right-Mic-Ground, so it definitely won't work with iPhone headphones (which are Left-Right-Ground-Mic). However this does mean it may work with headphones from other vendors that have the same connection order, like Nokia, perhaps.


How to create a newline on keyboard I would like to know how to create a newline on the current android keyboard (for example in a sms).
And if it could be entered - would it be displayed?

Edit:
If you've got Android 4.1.

It is just below the delete button.

Edit2 :
For Android 2.X it still is the question, where to find it.

Simply press the enter/return button in your key board. It is located at the right botton corner of your keyboard.

In some cases, this button sends the SMS (or submit applications, in cases of forms in websites) If your device does that, simply hit enter/return button while holding the shift  button or the upside arrow

Hope this helps.


Notification icon that looks like 2 arrows inside a circle with leaf on Huawei device I have a Huawei Mate 9. The notification icon looks like this:

  2 arrows inside a circle with leaf

Things that I have done:

Tried to find this on Google but returned no results
Checked my apps icons, nothing matches

First, I thought it belonged to Snapseed, but it's not theirs.

That's a notification originating from the Data Saver feature in Huawei ROMs (EMUI 5.0).

Data saver helps to reduce data usage by preventing background apps from sending or receiving data and limiting the data access frequency of running apps.

  When data saver is active, a data icon with a leaf will appear in the
  status bar. This may prevent users from receiving updates from emails,
  chat and other social media apps, and images will only be displayed
  when you touch them. To enable the data saver mode, go to Settings ->
  Mobile data -> Data saver.

How to root LG K7 (MS330)? I have a cleaning program on my phone and one of the program functions is to optimize CPU.When I try this, it says I do not have root privileges.

How can I get root privileges on my android LG MS330 ?

I'm suggesting something similar to what @Gokul NC has suggested. I'm assuming you have a computer, so this is a better option with a higher chance of successfully rooting.

Access your computer, go to the browser, and download Kingo root from https://www.kingoapp.com. Once it's downloaded, install the program, connect your device, and you'll be given further instructions within the app.
I have tested this method more than 10 times, you should experience satisfying results.


How can I stop Samsung Galaxy Spica restarting itself in a loop? I recently bought a used galaxy spica its in really good condition and etc..but when i launched it up there is something fishy going on...

It restarts in a loop...

As in, it boots up, i can use the phone for around minute or so, then it restarts...then again i can use it for a minute or so...and it restarts...i cant call or anything cause it restarts all the time.

It has been updates from the original 1.5 to 2.1 eclare, if you know a fix, please do tell.

If it was working before, try uninstalling the app(s) you put on it most recently.  They might be the problem.  After that, the first thing to try is probably a factory reset.

Edit: OK, so basically your ROM is totally screwed up.  I would just replace it.

Some official firmware is linked in this XDA post.  Download whichever you prefer, then use Odin as described below.

Download Odin for Windows (search for "Heimdall" if you are on Linux).  Then do the following:

Put your phone into Download mode

Remove the battery
Hold the VolumeDown, Camera, and End Call buttons:

Reinsert the battery.
After a few seconds a yellow triangle with an android in it should appear, you can let go of the keys since this is download mode.

Start up Odin.
Attach the phone to USB so that Odin recognizes it.
Load the .tar file you downloaded (the ROM) into the PDA field of Odin.  (If you got a .rar or .zip instead of a .tar, you need to extract the .tar inside the archive.  A .tar.md5 file is fine.)
Optional: Load the 512 .pit file into the PIT field of Odin and check "Re-partition".  You should only do this if you screwed up the partitions or perhaps if flashing without this doesn't work.  Make sure you have the appropriate .pit file for your device variant.
Hit Start.  Odin will tell you when it's done; if it fails, reboot your phone and try again.  (This happens occasionally).

Note that you do this at your own risk; Odin is very powerful and misusing it can damage your phone.  I've used it dozens of times myself safely.


How to root my Motorola Flipside? I am a relatively new Android user, but I have a bit of experience with Linux.

My new Motorola Flipside MB508 has quite a few unwanted preinstalled applications on it, which I would like to remove. However, I need to root the device to do this.

What is the easiest way to root a Motorola Flipside on Linux?

*edit* I tried using SuperOneClick, but I am running Fedora (17) and it doesn't work in Wine.

AndroidEvolved has guides for rooting your Motorola Flipside.

The easiest solution is to use SuperOneClick.

Download SuperOneClick, and extract it.
Connect your device to the computer. Ensure that SD card is not mounted. If it is mounted, unmount it.
Enable USB Debugging from Phone –> Settings –> Application Development –> Development.
Open SuperOneClick.exe.
Click on Universal tab if you are going to root any Android device like Nexus One, Galaxy S, Droid etc. Click on Samsung Captivate if that's your phone.
Click on Root tab and wait for the process to finish. [this will take some time]
Once completd, you would get a popup box that would confirm that rooting has been successful.
Restart your phone.

Restoring /system but not /data within TWRP I want to restore a TWRP backup on my Samsung Galaxy S6 (SM-G920F), to get back from a custom ROM (9.0) to Stock (7.0).

Restoring /system goes fine, but TWRP throws an error when it comes to restore /data : "extractTarFork() process ended with ERROR: 255
My question is : can I restore only /system and boot my original ROM ? If that doesn't work, how can I fix this error ? (I don't have a sdcard)

[Can] I restore only /system and boot my original ROM ?

It depends upon what lies in the backup. If you took the backup of your stock ROM and you're referring to the same backup, then yes, restoring /system using that particular backup would restore stock ROM. But you would need to restore /boot as well since that is part of stock ROM too.

However, if you must restore a different ROM, even if it is a stock ROM, it is a good practice to do a clean flash or atleast overwrite existing /data and /cache files with the ones in the backup to avoid conflict between various versions of files/apps which can cause bootloop or battery drain or whatnot.

In your case, since you cannot restore /data from the backup, I advise you to take a complete backup of your current ROM (including userdata), then reset /data (except /data/media) and /cache, and then restore /system and /boot from stock ROM backup. In this way, you would end up with a pristine stock ROM and can always restore /data when you manage to fix that error you mentioned. This is the path of least problems.


What is this lockscreen app? So sometimes when I try to unlock my phone I am greeted with this:

When I swipe up I am greeted with my regular lockscreen. Why exactly am I seeing this lockscreen? It appears randomly, does not appear every time. I dont have any lockscreen app installed. I am using Android 5.1 with stock launcher.

it looks like the Go Launcher locker app.... Just by the four petal clover  ...

Also King root makes a lock screen like that


UDP multicast with reverse tethering We are using a Wi-Fi network to communicate with other devices running our applications. And, we are using UDP multicasting.

However, due to some new restrictions we are no longer allowed to use wifi.

Is there a way to connect all the devices (via USB) to different computers (connected to the same local network) and have them all receive and send data with UDP multicasting?

We don't need internet, just the LAN. This is only used for testing purposes.

I am looking at this post about reverse tethering. Has anyone used UDP multicasting with this setup? Will the mentioned method solve my problem?

We do not currently have a linux machine setup and it would take us a while to get one setup. So if anyone could confirm this, from experience, before we start doing down that road, that would be fantastic.

Instead of going the whole "multicast over reverse tethering" way, which to me, doesn't make any sense at all, you should evaluate if a VPN setup with multicast enabled (plus optionally reverse tethering) may be a solution to your problem.

On a second thought: VPN + reverse tethering is basically "multicast over reverse tethering"


Samsung Galaxy Buds immense RAM requirement I was about to buy some Samsung Galaxy Buds but then saw in the system requirements that they required 1.5GB of ram to operate!

"Compatibility" section under "specifications"
https://checkout.telstra.com.au/consumer/rewards/headphones-speakers/145

I'm using an old S7 Android Galaxy phone. Right now it is using 2.9GB out of it's available 3.5GB of RAM just with the apps I have open.

I'm worried that my phone doesn't have enough ram to use the headphones.

Do the ear buds really require 1.5GB of RAM to operate?

I think this is just a misunderstanding:

The Galaxy Buds don't need 1.5 GB RAM free (nor do they use 1.5 GB RAM). The requirement means that your Android device needs to have at least 1.5 GB RAM installed in total. How much is free at the moment is of no concern (this is managed by Android).

Therefore older devices and low-cost devices with 1.0 GB or even 512MB RAM are officially not supported.

Your Galaxy S7 has 4GB RAM in total, hence you are fully compliant with the requirements.


Mirror/push Android notifications to iOS device I have found an interesting app named Klone. Basically it mirrors the notifications from Android to iOS, but it is no more supported and the iOS app instantly crashes.

I know that there is a bunch of services allowing the transfer from Android or iOS to Windows or Mac, but I was unsuccessful in finding a working alternative to Klone.

Is there any alternative way to achieve this feature?

Okay, I found an answer by myself.
First we need to download Pushbullet on the App Store.
After all authorization and stuff, we go to our android device and buy Tasker. Then we download Notification Listener and Push Tasker.
We create a profile by choosing plugin-notification listener-posted and select the applications.
Then we make a task where we choose plugin-push tasker and choose the desired notification.
Now we just have to keep Notification Listener running.

Not receiving WhatsApp messages unless I open the app when on 3G (on WiFi there is no delay) I have recently bought a Samsung Galaxy S4, Android version 4.4.2, and for some reason I only receive my WhatsApp messages when I open the app. This only happens when I am on 3G. When connected to a WiFi network, there is no delay at all.

I have uninstalled and re-installed, I have checked the restricted data setting (it is not ticked).

What did I miss?

Samsung phones have an option to sync data in the background, disabling it, saves data, as updates are only checked for when an app is open (email/im/whatsapp etc). You need to enable that (see green icon in image below) to let your apps periodically check for data.

Is it normal that more than half of RAM use can't be accounted for? I have a Samsung Galaxy phone and it typically says something like 705MB used 101MB free. This is a phone with like no apps except what sprint put on there. I've added up the running services and it comes to 279MB of RAM use. I can't figure out where the extra 400MB usage is coming from.

Pretty much. As Lie Ryan mentioned in his post:

Most smart phones are designed as a System-on-Chip; which means that
the CPU, RAM, GPU, device controllers, etc are all in a single chip.

The physical memory chip capacity is shared between different parts of the hardware (SoC). So the amount of memory available to your applications is what's left from the original allocation.
In addition, just like any Linux system, Android is optimised to use  as much RAM as possible, because that's how it was designed to work.
Furthermore, android system has a built in memory management system called Minifree. Basically operations like memory allocations to applications are done for example instructing the system how much RAM to leave free and available, cacheing 'often used' apps in memory, etc.
Here is the basic categories of minifree memory allocation to applications:

Foreground App: This is the application currently on the screen, and
running
Visible App: This is an application that is open, and running in the
background because it's still doing something
Secondary Server: This is a process (a service that an application
needs) this is alive and ready in case it's needed to do something e.g
launcher, UI etc.
Hidden Application: This is a process that sits idle (but still alive)
in case it's needed by an app that's alive and running
Content Provider: This is apps that provide data (content) to the
system. If they are alive, they can refresh and provide the content
they are supposed to at the set interval. If you kill them, they can't
of course. e.g Contacts, calender etc.
Empty App: These are apps that you have opened, but are done with
them. When an activity is ended, instead of killing it off Android
keeps the application in memory so that opening them again is a faster
process.

Given this whole range of minifree allocations, its possible the application may not be visible but busy carrying out useful tasks requiring RAM, also even when you've killed a given app, there are high chances is stored as an 'empty app' (meaning its lodaded into RAM so that executing the same app again will be fast).
All this occurs at the expense of overall RAM on board and as a result you always get a lower RAM reading than anticipated, since mostly is is cached as explained above.
While you can reset or tweak default minifree values, I believe seeing lower RAM readings when not using lots of applications is good since you are guaranteed execution will always be fast than starting to load an application into memory every time.
Basic notes

some RAM is shared between hardware
some RAM is allocated to hidden apps, content providers, empty apps which may not be visible in usage statistics, but its still important for improving device performance.

Change the date and time of one app I have installed a 7 day trial app. Changing the date and time in the phone can "evade" the version and trial and continue to use it. But this privates the fact that I've busted in every app. I wanted to know if it was possible to change the date of a single app even by changing the source code of 'App. I hope someone helps me and thank you in advance

AFAIK this is possible only if you have Xposed framework (hooking another app).
