Galaxy can't boot up, stucked at Samsung logo I recently upgraded my stock ROM of my Galaxy GT-p1000 from Froyo 2.2 to Gingerbread 2.3.6 and got stucked. I used the Odin to flash the ROM, it was successful by indicating that the ROM has been flashed OK, it rebooted and hanged at Samsung logo there rebooting & loop back to restart rebooting again over and over. Someone told me something about flashing the boot image with ADB, I do not even know what's ADB talking less of where find. I'm stuck, what should I do for my tab to boot up?

Since you said you have aready use Odin to flash, I think you know how to get these necessary files: Bootloader, PDA, PHONE, CSC, PIT.

Then, let's start.

Force the device to the upload mode by this way: simultaneously press power button and down button.

When the device is in download mode, plug Odin software and flash ONLY bootloader file (normally bootloader file is like this: BOOTLOADER_DEVICECODE.tar.md5 ).
After that, flash again with all PDA, Bootloader, CSC, PHONE and it's ok without PIT.
You should use the lastest version of Odin, as I am now using ver. 3.07.

Please feel free if you need more help.


Android File Transfer cannot connect to device from Mac Trying to find a way to transfer a video file onto my new S7 Edge from my Mac and it seemed like Android File Transfer was the only way to do it, but no matter what I do, I can't get past an error message saying "Could not connect to device. Try reconnecting or restarting your device."

I've restarted my phone and my computer, used different USB ports, uninstalled and reinstalled the program itself, and still no luck :( I've heard that the Samsung program Kies can cause problems, but I've never installed it. Help?

Running OS 10.12.1

My MAC is running MacOS 10.12.2, and my phone is an S7 Edge running the UK release Nougat 7.0. With Android File Transfer (AFT) I was also getting the error "Could not connect to device. Try reconnecting or restarting your device.", until I uninstalled Kies on the MAC. Thereafter AFT connected to the device and I was able to transfer files from the phone simply by dragging them to a(ny) folder on the MAC.

I have USB debugging enabled, MTP mode selected in phone's settings, and I had to respond "Allow" to a pop-up on the phone.


Hide Whatapp message preview on the front screen On new Samsung A3 2017, I want to hide Whatapp message preview on the front screen but keep the sound.  Is this no longer possible?

Thanks

Did you check at Settings >  Lock Screen & Security > Notification on Lock Screen? There you can hide notification for specific apps.


SuperUser doesn't give/prompt root access I was trying to move GoogleMaps on SD-Cards using Link2SD.
When I tried to do so I got a message stating

  Link2SD could not obtain root access.
  if you have root access make sure you respond 'Allow' or 'Grant' to the superuser request

Then I opened SuperUser to check the application list. I was surprised to see that there were no apps there! The last time I have checked there were some apps there(Link2SD, BatteryDoctor, TerminalEmulator).

Searching through the net I read that if an app needs root access, it will ask for it. The next step was to see, SuperUser's settings/preferences.

The Automatic Response is set to Prompt
Notifications are ticked
Notification Type is set to Status Bar
Use Advanced Prompt isn't checked

Navigating through Link2SD, I've noticed that Link2SD was updated. The next thing to do was to uninstall it and install it again. The first time I run it, it never prompted me to give it root access.

What may be wrong? Is there a way to give apps root access(by "brutal force")?

Download Root Checker and see if phone is still rooted. If it isn't rooted anymore, re-root your phone.


Android: Cannot open apps on SDcard I accidently deleted some folders on the SDCard, and now I cannot open any apps that were installed on the sdcard like angry birds.. These apps are being shown in the Settings, but I cannot move it back to phone. Only thing I can do is uninstall it. Any idea how to get these apps working? I really dont wana play angry birds from the begining all over again :(

No idea about other apps but Angry Birds save data is stored to /data/data/com.rovio.angrybirds/files

If you copy over the contents to a separate location, then re-install Angry Birds and move back the old save data into the same location after re-installing Angry Birds, you should have the same save state.


Gmail notification on lock screen does not show subject On my new Samsung Galaxy S9 running Android Oreo, new email notifications (Gmail app) do not show the email subject. This happens even if I just have a single email notification. If I unlock the phone and check the notification shade, it has all the required details.

I am wondering if there is a setting on Samsung phones that causes notification details to be hidden on the lock screen for the sake of privacy.

This was working fine on my Pixel.

Found it! The setting to change is here:

Open the Gmail app. Go to Settings > (Email address) > Manage Notifications > Lock screen > Show content


How do I decrypt files on my SD card that I encrypted using the Settings? I have files that I used to copy from my SD card to my PC using the USB Mass Storage option under the "USB connection" pop-up.  I checked the flag under Settings->Location & Security->Data encryption->Storage encryption and now I can't read new files of these types (e.g., .jpg and .txt files). I tried unchecking the box -- a message appeared saying that future files will be decrypted, but existing files will remain encrypted.

How do I access the files that are currently encrypted and/or decrypt them?

I sent this question into Verizon Wireless as well.  Here is their reply:

  Thank you for contacting Verizon Wireless through our website...I
  understand that you've been having an issue trying to decrypt files on
  your handset.  At this time Motorola hasn't provided an update for
  your phone to be able to do this.  Without that, we're unable to
  assist you because this is a phone issue and not a network issue.

So it looks like Ryan was correct in his comment that this is an issue with a Motorola OS add-on, not vanilla Android.

Since originally asking my question, I experimented some more with my phone.  My phone has 2 check-boxes for setting encryption: one to encrypt the SD card (that I mentioned in my original question) and one to encrypt the main phone memory.  When I unchecked both boxes, my phone decrypted all files, both on the phone and on the SD card.  So, that is my solution for now.

Thank you Ryan for your comments -- they helped lead me to this answer.


What's a secure way to message/talk to someone in CM9? I'm using CM9 nightly (20120712 i.e. today).

I need to talk securely, without the chance of eavesdropping, to someone who also has CM9 nightly (not sure how up-to-date but not more than 1 month old).

What apps/webapps can I use to do this? Ideally I would like to be able to talk but messaging/email would be fine.

Are apps like Twitter/Gmail/Gtalk secure end-to-end? I do have HTTPS set up on my account but don't know how far it applies to the mobile version.

But really I am willing to use anything as long as it known to be secure enough to prevent MITM attacks and eavesdropping by unwanted parties.

I found the following but I don't think this is a definitive answer though it looks close to what I need, secure end-to-end encryption with no chance of snooping/sniffing/MITM.

I wasn't fully aware of OTR though I had heard the term used elsewhere but didn't know the full implications. I think OTR is what I'm looking for.

Still looking for further input though.


XXDMC3 update for Galaxy Note 2 What exactly does it fix? By googling I got to know that it fixes some bug related to the lock screen. Do any one know of that bug. Got to know regarding this as I got a notification regarding software update in the device.

The update is just a bug fix update, no new features. The lock screen bug that you mentioned allowed bypassing the lock screen for a short amount of time, details can be found for example on TheVerge or AndroidCentral.


How can I access my Galaxy S5 from a PC to retrieve all of my files? I broke the digitizer (LCD display/touch sensor underneath glass screen). The phone still turns on and can connect to computer but I can't access it because I have a passcode lock on it and it doesnt give me the option to type it in on my computer. The screen is completely blank and un responsive. Is there anything I can do to retrieve my files?

It's possible to backup or access your files from Kies 3 installed on your PC even if it is password protected.

I've also tried it on my Galaxy S4 GT-I9500 and it worked.


How exactly does "root" work? Do all applications run as root on my phone after rooting? I've been reading about rooting the phone, but I have some concept doubts: when you buy an Android phone from a carrier, you don't have "root" access. When you start your phone, does that mean a "user" account (like I have on at Linux/Mac, '/home/myself') is used? Does '/home/myself' or similar exists in Android phones?

If I "root" a phone, will I start the phone as root when I turn it on? Will all applications now run as root? Or when they try to be run as root, I will need to permit them so?

If Android is essentially a Linux, to backup my device, shouldn't I just be able to connect to root it, do a full tar -cvzf / and then scp to somewhere? Why would I need to have Nandroid and these full-blown solutions?

When you start your phone, does that mean a "user" account (like I
  have on at Linux/Mac, '/home/myself') is used? Does '/home/myself' or
  similar exists in Android phones?

No. Android was designed for a single-user system, and a lot of the design decisions were made such that /home/myself no longer exists. In Android, Linux kernel's multiuser capabilities is used to enhance security instead, by running each application as its own user; therefore isolating each application's data from each other.

  If I "root" a phone, will I start the phone as root when I turn it on?
  Will all applications now run as root? Or when they try to be run as
  root, I will need to permit them so?

No, No, Yes. In modern rooting methods (which is basically every rooting methods except for the earliest ones), there is an application called "Superuser" which is used to manage applications which are allowed to gain root access.

  Since Android is a Linux, I'm interested in having access to a
  terminal and some unix utilities (ssh, rsync, etc). I don't mind
  having to use a bluetooth keyboard and vi (to edit /etc/hosts for
  example) if needed. Is this possible? Can I have a terminal with a lot
  of unix utilities (I know busybox is available)?

Yes, a shell exists (but it's not the bash shell). You may need to install Terminal Emulator to access it (some custom ROM installs it by default) or use it as a remote shell using ADB. Because it doesn't use bash, the terminal will be slightly different from what you're used to seeing in regular Linux distros (notably it doesn't have autocompletion) and most shell commands that you consider "standard" does not exist or only exists in extremely barebone form.

If you're using the terminal a lot, it is possible to install busybox and bash for a more familiar terminal experience; you can also install GNU userspace utilities, but you'll need a fairly high-end phone with heaps of disk space for it.

In short, what you want is possible; although a lot of the tools aren't installed by default on manufacturer ROMs. It takes a fair bit of work to install all those tools yourself, the easiest and fastest route is to install a custom ROM that provides those tools like CyanogenMod.

  If Android is essentially a Linux

Android uses Linux kernel, but it is not a GNU/Linux and does not use the typical GNU userspace programs. Instead it uses the toolbox userspace, which is a very minimalist userspace (even smaller than busybox, toolbox doesn't even have a cp, you have to use cat instead to copy files). Some custom Android ROMs installs busybox by default.

  to backup my device, shouldn't I just be able to connect to root it,
  do a full tar -cvzf / and them a scp to somewhere? Why would I need to
  have Nandroid and these full blowns solutions?

which is essentially what Nandroid does (strictly speaking, Nandroid backup is more like backup with dd rather than tar though), except with a much more convenient GUI. Most people, even power users, don't like typing complex commands on the small keyboard or having to connect an external keyboard every time they want to backup (and 99% of the world has a Terminal-phobia). It's much easier to just start an app and click a button and have all those done for you.


Where do I download HBOOT 2.16? I need HBOOT 2.16 to flash my preferred ROM on a HTC One S.

I can't figure out where to download the firmware itself. The only page I've found which even vaguely resembles clear instructions is this one but the download link for the firmware is broken. The other pages I've seen present a very muddled picture and no links through which to download the actual firmware.

I have a rooted device, S-OFF, super CID 11111111, formerly H3G__001 I believe.

I'm going round in circles trying to figure this out. How do I upgrade my firmware?

Assuming you have an S4 variant.

Check this XDA-Developers thread out - latest official (but unofficially obtained) firmware at version 4.05.401.1, with HBOOT 2.16. Link is hosted on AFH and is pretty good in quality.


Unable to download apps from Play Store using mobile data I have Mi4i mobile. I am trying to download  applications from Google Play Store- when I click on Install it  displays  "Waiting for WIFI...".

I am on mobile data, but it is not downloading through mobile data.

How can I download through mobile data?

For MIUI 8(previous versions also).
Check your 'Security' app's -> Data usage -> Restrict data usage -> System tab. Within system check Downloads is allowed to use Mobile data.


How to change default video player app inside Hangouts A video appeared inside a Hangouts chat stream and when I clicked it, it asked me which installed app I intend to use for playing that video.

I accidentally picked some casting app, but apparently (and surprisingly) the Use as default app was also checked, so whenever I click a video inside a Hangouts chat stream it tries to cast to a non-existing device and fails.

The system-wide video app is set to a normal video player app, but I can't find out how to set the default app for playing videos inside Hangouts.

Any idea how to reset it without uninstalling either app?

So far it is not Hangouts that need to be cleared in this case but the app which got registered as a default player.

Goto Settings -> Apps -> [Select the App that open when you play video inside Hangouts] -> Click Set as Default -> CLEAR DEFAULTS


What does "no visual interruption" for notification importance mean? When configuring notification categories, you can change the Importance to Urgent, High, Medium, and Low. The description for Low says "No sound or visual interruption." What does no visual interruption mean? I want to set certain notifications to the lowest possible, but I still want them showing in the notification bar, so if no visual interruption means that it will disappear from my notification bar, then I'll leave it at Medium.

No visual interruption means that the notification won't peak at the top of your screen. It will still show up in the notification bar.

https://www.androidcentral.com/notification-channels - This article further confirms that setting notification importance to Low just means you will not be getting any indication that you have received a notification, the notification will still show up in the Notification Bar though.

The only way a notification would not show up in the Notification Bar would be if you completely disabled notifications for an app.


How can i run Wifi direct in my andrioid ICS tablet? i have an android ICS tablet (no bluetooth) , I want to share files wirelessly...
but in ICS wifi direct is not there.I heard that wifi direct is not any hardware plugin - it is based on OS and can be run in android ICS.
So please if u know tell me step by step instruction.
...

Install and run ES File explorer on both Android devices and connect them both to one Wi-Fi access point. Long press on the file and use Send option and choose scan. After some lag the target device will be listed and just selecting it will prompt for confirmation on the target device. Once confirmation is accepted, the transfer will take place.

You can see ES File Explorer's help page for more info.


deleted the google shortcut widget which shows all the google apps I accidentally deleted the google shortcut widget which shows all the google apps on my x play android lollipop how do i get it back?

It isn't a widget, but just a folder where app shortcuts are put together by default. You can create them by just "drag and drop" an icon over another icon and create a folder. Then you can rename it to "Google" or an app category or whatever you like. Look at the screenshots for a more clear understanding on how to bring back the Folder,

Screenshots - Click to enlarge image:

Here's the default folder named Google with Google apps inside it,

Pull Google apps from your Menu drawer by long pressing it and pasting on your home screen. Now merge these two app icons to create a folder.

After merging the two icons it will be displayed as a folder named "Unnamed folder". You can press and edit it's name to "Google".

Finally, after you put all your Google apps into the folder, it would look like this,


Why does Phone storage get full with ambiguous "Other" storage that wont let me use more than one GB of the supposed four that i have My HTC keeps running out of phone storage, there is supposed to be four GB of storage but it always gets full at one GB of app data and 3 gigs of "Other" data which isn't cache and I can't even see what it is, I've had this problem with previous HTC phones, I've done what I can to move as many apps to my SD card but most can be moved there. What is this Other, is it important data, and can i move it or get rid of it.

Screenshot (click it for larger variant)

"Other" is just anything that doesn't fall into one of the other categories.  If you install a file-manager app (such as OI File Manager) you can browse through the actual files and see exactly what's there.


Stop automatically setting apps as default I have an AT&T Samsung Note4 currently running Marshmallow 6.0.1.

In the past it and all other Android phones used to prompt me for and app
to open files or links with. The menu wold have a sellection of apps and 'Once' and 'Always' buttons. An app would only become default for a given link/file type by pressing 'Always'. Otherwise I would get prompted each time.

Not too long ago this behavior changed. The 'Once' and 'Always' buttons are gone and apps automatically become default after the first choice. This is fine for some files/links but not others.

There are many different kinds of things I want to do with some file types (eg pdfs) and I use different apps for each. Now I either have to unset the default each time or open the file in whatever the current default is and than 'share' it to the app I actually want. This is a pain and not all apps are equally good at sharing to other apps.

How can I get the old behaviour back? Or at least select some file/link types to not have a default associated with them? I know how to unset default apps in settings; I am after a way to avoid needing to do that for files/links I open with multiple apps.

I am not sure if this change is due to some update or if it is something I enabled unintentionally
FWIW, I also have a Huawei running Android 4.4.4 that still has the old behavior

This question is about the same problem in a specific context, but i am after a solution to the general problem that none of the commants & answers there address.

I'm having the same problem but it looks like it's corrected in later updates of marshmallow according to https://www.greenbot.com/article/2991086/how-to-change-your-default-browser-and-phone-apps-in-android-marshmallow.html
So I'm going to try updating and hope it works for both of us.


How to remove app shortcuts from default opening types? I like to remove some of my app shortcuts from default opening types, such as some app I already removed like browsers (some Chinese browsers I downloaded when my Chrome had some issue in China) but still would show up when I click on a web shortcut (and it prevent me from selecting Chrome as my default browser). And some duplicated shortcuts like wifi assistance (when I want to open wifi setting it will show two of them). And some shortcuts I don't even think they are in the correct category like Taobao (a Chinese shopping app) would want to be open when I open a web link or a photo.

P.S., looks like Chinese app makers really mess up your Android system with tons of random default app shortcuts.

You normally cannot adjust default applications individually once they have been set. The best option would be to navigate to the app in the Application Manager and press they Clear Defaults button. You will need to set other default for the app again, but it will clear out the defaults you don't want as well.


Can't boot to recovery neither rom I made a mistake while trying to flash an stock rom in my XT1644. While unlocking bootloader, I didn't realize I had to check the "allow OEM unlock" in developer options. When I thought unlocking had gone good, I started flashing manually a stock update, and everything failed. Now, I can't boot into recovery nor flash a recover nor unlock correctly bootloader, since "allow OEM unlock" still appears on screen.

Tried using RSD Lite, but doesn't work.

How can I unlock my device without checking the "allow OEM unlock" since I have no OS nor recovery?

It's bricked. Happed to me also.

Can I launch a shell script from home screen? There's one tweak of my phone I'm applying/removing through two some pretty simple shell scripts. But going to terminal emulator and typing the script names each time aside, the tweak actually makes on-screen keyboard unusable and may necessitate adb access to start deactivate.sh

Is there a way to launch the scripts from the home screen - just place them as icons, the way you can just double-click a .bat file on your desktop on Windows?

YES,
Download terminal emulator app from playstore.it gives the access to commands directly by using Widgets.through this you can place the widget in homescreen and launch a command in a 'click'.


How to disable Notifications for Github Emails on Google Inbox? I turned the data synchronization on, and I get the notifications of Google Inbox. It works fine for "important" or "primary" emails, but it notifies me for Github emails too. How do I disable it -just because it is not really important/primary-?

You can't do it from within the app as you can read in Google Product Forums , open since last two years

Alternatively, you can try automation.  I prefer Macrodroid, being easy to learn and free (upto 5 macros)

Create a macro

Trigger: Notification → Notification received  → Select Application  → Inbox  → Text content contains  → Enter here the text common to GitHub mails like maybe yourname@ GitHub.com? ( Check your notifications to see what easily identifies these )

Actions:

Clear Notifications  → Clear all
Optional if you don't want notification sound Volume Change  → Set notification on slider scale to zero

Constraints : Leave blank


Opening links from app in Google Chrome Incognito or Firefox Private Browsing mode When I tap on a link in any app it shows me installed browsers on my HTC One X. The list includes Opera, Internet, Chrome and Firefox. Is there a way by which I can include options of Chrome (Incognito) or Firefox (Private Browsing) in that list so that I can open links in Incognito / Private Browsing mode?

Unfortunately I don't think there's any way for a user of an app to do that, I'm pretty sure it would require the developer to add that extra "intent" as an option to their app before it could appear in that app chooser box.

There are apps that specialize in this behaviour though, and should appear as options in the app chooser box for web links:

InBrowser is "a fully featured incognito/private browsing experience", which should appear in that list of browsers and work as an incognito browser.

Incognito Browser "automatically operates in incognito or private browsing mode"


Screen turns off during call with Tecno F7 Why does my screen go off during a call? It doesn't turn on even when I press the power button. It only comes back after the call.

Disclaimer: I have a Samsung Galaxy S4

Just giving this a shot in case it works. Are you using the stock Phone app? Maybe you have the Turn off screen during calls checked.


Wi-fi immediately disables I have a Samsung Captivate.

This week, it's wi-fi stopped working.

To be more precise, it's wi-fi recognizes there is a wi-fi router nearby (my home's), and tries to connect.  But it immediately disables and tries again in an unending loop.

I have not tried connecting on another hotspot.
I have installed a couple of programs this week, but I don't remember any of them being wi-fi related.
I recently put JuiceDefender on aggresive mode, but now I've disabled it, and wi-fi still doesn't work.
Tried enabling/disabling Flight Mode, but no success.
I've restarted my phone a couple of times.

UPDATE (04/15/2011)

I managed to connect to a nearby hotspot, so I'm guessing the router is the problem.  It is a 5yrs+ old router (linksys).  What's strange is that my PC is connected to the router by LAN cable, and still works.  Also, I was able to enter it's configuration page (192.168.1.1).  Probably some hardware is damaged.

UPDATE (04/16/2011)

NOW I´m confused.  I connected to my router with an old low-grade tablet I forgot I had, with no problems.  I'm guessing now that the problem must be some app I installed on my phone.

CONCLUSION (04/16/2011)

I just had to press the router's reset button on the back, and now my phone is connecting.  Thanks to all who commented!

Delete the saved network from the phone, then reboot both the phone and the router and try again.  If that doesn't fix it you'll need to test with another network to see if it's a phone issue or not.


Why must my device be compatible with a certain ROM before I flash it to my device? This it the explanation telling me not to install a custom ROM without checking the device's compatibility. "Now, be careful as each custom ROM comes with a version that is suitable only with one device; you can’t install the same variant of firmware on all the Android devices as the same is not compatible."

But, I'm using a HP Slate 7, there isn't an official thread for this device on XDA Developers, and the furthest I can go is to root my tablet. Other than that, there are no custom ROMs specifically for this device.

My question is, why can't I install a custom ROM if I follow all the correct processes for flashing a custom ROM, even if my device is unsupported? Is it purely because of the bootloader? Or the kernel? I'm fairly new to Android, but I've been reading up on new terms, so can I have some guidance?

No long explanation needed, the reason is quite simple: Different devices come with different hardware components, such as the camera or sound "chips". Those require special drivers, which are in most cases proprietary and not part of AOSP (which is the "Android base code").

This means, each ROM must include device specific code, and thus is specific to the device it is created for.


Can I use my bootloader-locked phone with a different network? I just bought an Xperia Z and the bootloader is locked. Do I need to unlock it in order to run it on a new SIM card and can I switch to Virgin? It's OK if I can't: I will just buy a Bell SIM for $10, but will the phone be able to be switched to Bell pay as you go? It was previously on the prev. owner plan with Bell.

The bootloader being locked has nothing to do with whether it's SIM-locked to a particular network. It just means you can't flash a custom ROM to the device (without unlocking the bootloader). You don't need to unlock the bootloader to change SIM to a different network, but if it's SIM-locked to a particular network, you need to unlock it from that network.

Whether you can switch to a PAYG SIM is entirely up to the carrier, and nothing to do with Android. You should check with the carrier.


Reverse polarity damage I need help. I was using a generic usb charger to charge my android phone and it was charging fine but somehow the polarity was reversed. After being plugged in for some time, the phone became very hot and can't power on now. How badly is it damaged and how can it be fixed?

If really damaged - only by re-soldering broken components by new components.

But HOW? USB polarity is declared in standard, cable is impossible to insert at wrong position without break of connector.


Cannot connect to Network - EMERGENCY CALLS ONLY I was trying out some ROMs which I downloaded from needrom.com. At first it was fine. Then when I flashed a particular ROM, I started getting "INVALID IMEI" and could not connect to the network anymore.

Luckily I had a full backup of the phone taken with TWRP. I could not see my backup listed in the TWRP that came with the present ROM. So I flashed the Recovery with which I backed up the phone. Then I could see the Backups listed.

When I tried to restore it, it failed with this error:

Unable to mount '/data'

I guess the partitioning changed. Anyways, I could restore 'Nvram' alone and the INVALID IMEI got replaced by "EMERGENCY CALLS ONLY".

How do I fix this? Can I somehow restore the backup (by fixing Unable to mount /data)?

Microphone not working properly during call (LG G2) I have an LG G2 (d802) with a rooted Lollipop rom installed. During any call the person I'm speaking with has difficulties hearing my voice due to stuttering and distorted sound. Sometimes they stop hearing me altogether and I found out that if I mute and unmute the microphone it starts working again for a very brief period of time. Before dispatching it to the repair shop, is there anything I can do to try and fix the problem? To rule out any (possible?) software bugs. Thanks

Give Microphone Guard app a try.

My Mobile was working only on Loud-speaker (software issue) and it helped me.


Got 220 MB space free but still not able to download apps I have a second gen MOTO -E . I have 220 MB free in internal storage but I can't download apps of even 3 MB What should I do ?

To be able to download apps in the Play Store you will need at least 510mb available or 10% of the internal memory. Also depends on the size of the app you download. The Android OS uses the internal memory also to RAM purposes so is very relative the available space. Try to clear cache and data from GPStore, GPServices, Reset Apps Defaults and also remove some unused apps.

How to prevent my Google account from acting like it's from the US? I'm from the Czech Republic and via some proxy I made my Google account look like a US-based one to try Google music etc. Now Google music with all access arrived in my country and it's cheaper than in the US! But Google remembers my account as being US-based so I still see the US price of $9.99.

Do you know how to change it back?

Try accessing via Czech Republic - proxy and then try again. Good luck.

edit: Login with your credentials via proxy from Czech Republic and hope that the price will be different from the US price.


Connect android tablet to internet via ethernet I am using an android tablet at my work place. For some weird reason, WIFI has been disabled in the tablet. The only way to connect to the internet is via ethernet.
At this point, I have a USB-Ethernet adapter. I am able to enable ethernet and connect. I even get an IP address assigned to my tablet.

But, the problem is, I am unable to access the internet on the tablet. When I try to open any application that requires connectivity to internet, I just get the error message "This application requires a working data connection".

Not sure if this is relevant, but I checked the file "sys/class/net/eth0" and it says "up".

Can someone help me out here?

Thank you ..

i had the same problem. EBay app told me the solution. My date and time were set manually in 2011. I set the good time and date automaticly and now my apps have access to internet.


3G Radio Always on When Screen On? According to JuicePlotter, my HTC Evo's 3G radio is always on when the screen is on -- even when doing absolutely nothing.  I tested this by turning the brightness down to 1 and opening the settings menu and just leaving it there.  The screen was set to never shut off.  I got pretty significant battery drain.

I ask because I want to improve my battery life when reading downloaded books with the Kindle app.  It seems to me that the radio should be in sleep mode when not in use.  I'd rather not switch to airplane mode because I'd still like to receive calls/texts.

To clarify:

I have a strong signal at all times
When the screen is off, JuicePlotter says the radio is off (and the battery lasts practically forever)
When in airplane mode with the screen on, JuicePlotter says the radio is off (duh) and the battery life is much better.
Android reports that my display only consumes between 5 and 10% of power
Android reports that Cell Standby consumes 30% (and that's with great signal)

I think these tests demonstrate that the display itself is not the problem, the radio is.  So again the question is:  why does the radio use so much power when the screen is on but it's not being used?

With cdma phones the data and voice use the same radio. Its going to run all the time anyway because its constantly syncing data, towers, location... If you want to stop it without turning off voice you should turn off the apn. Doing this will not put your radio to sleep but it will reduce your power consumption.  Check into apndroid or quick settings, and tasker to set triggers and automation.


How do I connect to PPPoE based broadband? I found same question in stackexchange, but it did not work out for me as mine is not an WiFi PPPoE issue. So I am posting this question here.I have installed Phoenix OS in my laptop. I don't connect to the internet with an WiFi router, but with a directly Ethernet port. Now how do I connect my android installation to this PPPoE broadband?

You need to know username and password to connect to the Internet using Ethernet port if you are using an Ethernet modem which is not configured.
Ask your ISP for the username and password.


Setting ethernet proxy settings without WiFi I'm playing around with the latest android-x86 (4.4) in virtualbox. The setup can connect to the external network only through a NAT ethernet device that is emulated by virtual box. This gets autoconfigured just fine and i can ping computers on my LAN.

If I export http_proxy=<host>:<port> in a terminal, I can wget web pages. However I am unable to set the proxy settings globally for all apps.

The proxy settings are displayed only after a wifi network is connected, and I lack any wifi devices in the virtual machine.

I have tried the following in the root terminal accesible from alt+f1:

setprop global_http_proxy_host <host>
setprop global_http_proxy_port <port>
setprop net.gprs.http-proxy http://<host>:<port>

But this fails to have any effect. Even new terminals lack the env variable for the proxy. These settings appear to be set when I check it by executing getprop

I found this link to the fragment that seems to display the proxys selector for the wifi.

Is there any way that I can manually set all the settings that are affected by this fragment?

This solution worked for me.

Just enter the following command in a terminal (change PROXYIP:PROXYPORT )

iptables -t nat -A OUTPUT -o eth0 -p tcp --dport 80 -j DNAT --to PROXYIP:PROXYPORT

Source: https://groups.google.com/forum/#!topic/android-x86/XfIRyHQ5nmk

I had too tried all your commands without success. I was stuck behind a proxy trying to setup Android x86 with a VirtualBox VM which only had eth0. I was stuck at the activation screen not resolving the needed webpages to continue into the OS. After running the above command, I was able to reach the web and continue. Results may vary per proxy environment.

Edit: This didn't get me too far, but it got me somewhere. The same trick didn't work for 443.


Can't download apps from Google Play store via mobile network I have a Sony Xperia sola in Egypt. I bought it with Gingerbread, then I upgraded to ICS 4.0.4. After the upgrade, I became unable to download any apps from Google Play using my mobile network, and while using Wi-Fi the download is slower than before the upgrade.

I tried all available solutions like clearing cache or clearing data from Google Play or Google Services Framework, in Settings -> Apps -> All. How can I fix this problem? As it is very serious, many times I'm at places without Wi-fi and I need to download a missing app, or upgrade another one.

This really sounds stupid, but when the time and date are wrong, most Google apps won't work.


My Samsung Galaxy S 2 indicates it is charging but doesn't My Samsung Galaxy S 2 indicates charging but is not adding charge to the battery. I have changed my charger many times but the problem continues. What's the solution?

There might be a problem with your micro-USB connector i.e the place where you connect the charger to the phone. Some times the pins present there bend out of place and so this can happen.

Take your phone for a repair.


Transfer files from recovery on a Nexus 10 My Nexus 10 won't boot, so I need to copy a ROM from my computer to the device. Since it won't boot, I need to copy it via recovery. I can flash recoveries as needed and install software on my computer as needed, but I need to get the ROM on there!

Use ADB on a computer while your device is in recovery. To copy a file from the computer via usb, use this:

adb push /path/to/local/ROM.zip /sdcard/

This will copy the local file to the device in the specified location.  Directories can be created on the device via the shell:

adb shell

and using the usual shell commands to navigate around and create directories. This beginners guide may also help you.

You might also consider getting a USB OTG adapter. This way you'd be able to put the files you need on a USB drive, plug it into your N10, and flash the files you need. I do it this way on my N7 with TWRP all the time so that I can erase everything on it without worrying.

How to keep Hangouts from adding a "1" before SMS shortcode? I frequently use SMS shortcodes to get my account balance from my bank.  I send a text message to the bank's short code (in this case, 728464), and my bank replies with a text message containing my current account balance.  I've been doing this for a while now with no issues.

I recently switched phones (to a Nexus 6 running Android 5.0.1), and now when I send my text to 728464, I get an error (from my phone, not from the bank) saying that the short code I am texting is not valid.  I noticed in the error that either Hangouts or Android seem to be prepending a "1" to the short code (see the screenshot).  I'm guessing that this has something to do with it.

How can I prevent Hangouts from adding this "1" to my short code (which seems to be preventing me from sending the SMS)?

In case it's pertinent, I have imported all of my SMS conversations from my old phone using SMS Backup Restore app, and have selected Hangouts as my default SMS application.

Save the shortcode number as +728464. Hangouts all think that +7 is the prefix, so it won't prepend the +1.


Corrupt Internal Storage File System I am using an original RAZR that is partitioned using Safestrap running stock 4.1 on one partition and CM10.1 on the other.

My problem is the internal storage (internal SD card I believe) partition running CM10.1 has a corrupt file system and I am having trouble running a check and repair. The internal storage always shows 0.0b available and no files can be saved to that disk space. The OS restores to default on every reboot, I'm guessing the config files are failing to save when I get through the setup.

Troubleshooting steps/questions so far...

Using Safestrap I have tried to wipe the system and all caches, then reinstall CM10.1 but no luck. The version I have of SS does not provide a file system check.
I can connect using shell and ADB, just not sure exactly what commands to run from there. Specifically how do I find out what file system to mount and how do I type that out as an argument?

Do I use the fsck_msdos program that I have available in the /system/xbin folder?
If so how do I find the file system information to complete the syntax for running the fsck?

If fsck is the correct method to repair where do I run it from? Stock or CM installation? ADB shell or terminal from a running droid OS?

I once tried to Format my microsd card in my razr with a safestrapped rom. My phone rebooted and I ended up having to reinstall my rom. buy a microsd card reader and format with your pc. If you have a friend that has a digital camera, you could ask them to format it for you. You would need a microsd to sdcard converter tho.


Hangouts application not always suggesting my contacts when searching I store all of my contacts under Google Contacts, which my Android phone uses/syncs (i.e., the Contacts application lists these, and only these, contacts).

I recently searched for "sergio" under the 2nd tab of Hangouts by clicking the "+" button to generate a new SMS message. I have at least one contact with this matching first name, yet Hangouts only suggests random strangers with this name, none of which are my contact.

After this failed, I used my Contacts application to find his record, where I clicked the sms/message icon. This redirected me back to Hangouts where an existing SMS conversation was loaded.  Subsequently when searching for "sergio", Hangouts now lists my contact under Phone Contacts, ahead of the random strangers it lists below that.

For other contacts, they just show up when I search. I can't find any difference between those contacts that don't show up and those that do.  Any ideas if this is a bug or a feature?  If it is a feature, how can I get all my phone contacts to always show up before random strangers when searching?

For those asking for a clearer, illustrated answer:

Click on the (+) New conversation
On the right hand of the search box, click on the really-nonobviously-a-modality-switch phone icon:

Search will now be limited to your Google contacts.

Presumably some designer made a bizarre choice to use a phone call icon to represent the phone address book.

Note:  When texting rather than calling, be careful not to click on the contact name rather than the small SMS icon on the far right as this will immediately initiate a phone call.  (credit to Dan Csharpster)


Is it possible to have my Android device see hand gestures to turn on the screen and scroll? While I am cooking with dirty and wet hands, I want to see the recipe on my smartphone without dirtying it.

How may I turn on the display and scroll without touching the phone?

Is there a setting or application that makes my device react on hand gestures to turn on the screen and scroll?

(I do not know how to categorize this question with the available tags if you know a better tag please feel free to improve the categorization)

I recommend getting Air Swiper with which you can turn on your device just by swiping above the sensor  (which is located with your front camera), and you can also turn it off by swiping as well.


Missing some of the applications while updating existing apps in my galaxy s3 While updating the existing applications like Google maps, Play Music etc from the play store in my Galaxy S3, some applications like Navigation & 2 more disappeared from my phone. why is this happened? What can I do to restore them?

Google maps new version is all rounder application for your navigation and maps, You can find that feature inside your new google map application itself, That's the reason why your applications has been some applications are replaced with brand new application which offer all features of replaced applications.


Is there a hands free way to manipulate pandora while driving? I was wondering if anyone knew of a handsfree way to manipulate pandora while driving.

(On Linux, there is an app available known as PianoBar, which is open source and can interact with Pandora servers without using an official client; this includes BASH integration, which allows you to....)

Well, that's neither here nor there, I'm in engineering school and I hardly have time to program any apps.

I have a Galaxy S4, and what I really want is a way to manipulate Pandora Radio while driving.  (They don't seem to have an disabled accessibility, either >.<)  It certainly does not have to be complete, but it should at least let me like and dislike songs without using my hands.

I'm really just looking for a way to listen to my music without having to look away from the road.

I've tried S-voice, and it can start Pandora, but after that you appear to be on your own..

Thanks for any help!

PS: Assume I have no more than an aux jack to use in the car, so the answer can't be "install something"... it's an integrated head unit.

This would really have to be enabled by the developers of the app, unfortunately. An always listening app would be very risky to distribute, as it would generate many complaints about battery life...

I have an Android Wear watch, which makes interaction minimal and on your wrist as you drive. This is my best suggestion, though this also would depend on the developers, if they have implemented Wear functionality.

I know this is a more costly solution than an app, but there's more to it than just this functionality. Wear apps can also implement voice functionality, so those developers better get working...


how do I know the time involved in updating the firmware of my samsung I5801 phone via KIES The official update for samsung I5801 is available now.

Has anyone done it before (using KIES, any samsung phone)?
How long it will take to update the firmware via Samsung Kies pc suite?
What are the additional things to do before and after I update my firmware?
(* I have taken backup of my contacts, messages and applications on the phone's memory card * I will reset my phone before and after updating the firmware using the settings -> factory reset option)

If something goes wrong then what can be done to revert.

Please help me as I don't want to fall in trouble after attempting an update.

Thanks

The actual update should take at very most half an hour, the download time may vary though.  Other than a backup, I don't see what else you'd need to do.

If you have trouble, come back and post a separate question with details.  The update usually either fails entirely (in which case you can try again) or works fine, you shouldn't end up in some half-updated broken state.


Use an Android tablet as a Wacom drawing tablet for a PC? Since a nice Wacom tablet is a bit pricey, especially for someone like me who doesn't do much graphic editing, I was wondering if it is possible to use a tablet (i.e. my Nexus 7) as a Wacom-esque drawing tablet when connected to a Linux computer?

I did a bit of searching, however most of the info I found is for using a Wacom tablet on an Android device. I've never used a Wacom device, however I have been doing some graphic editing in Gimp, and think it would be much easier than just using a mouse. And since I have a Nexus 7, it seemed like the logical place to start. I would have to use the Nexus as a USB peripheral for the computer, and I don't know if it is possible to transmit the touch screen coordinates to the PC.

If anyone can point me in the right direction, I'd appreciate it!

The GfxTablet project should allow you to do this.  It's network-based rather than USB though.


What are the custom roms available in market for android and ios for micromax funbook P 300? I am working to add custom rom that are available for ios and android,I need to add add custom rom in my android phones, I was using "androios" rom that is featured for both  ios and android, but its not rebooting properly in

  micromax funbook p300

Can any one please help me, Regarding Custom Roms that have features of both ios and android, to add in micromax funbook p300.

Firstly you can't install iOS on your Funbook. Any ROM(s) that claim in doing so are actually just running Android with a launcher that looks like iOS.

For information about ROMs for the P300 I suggest you read this thread. The number of working ROMs as is seems pretty scarce.

Also, when you root, unlock your bootloader or flash a custom ROM you void any warranty of your device.


What is the difference between Tesla, Tipsy and Validus builds? I want to flash Validus ROM on my OnePlus One. I looked up at the website of Validus ROM and they have not mentioned the difference between those three builds. When I checked some XDA threads I found that at least Tipsy and Validus builds  seem to have Status: Stable.

So what is the idea behind the naming scheme? They don't seem to be like nightly, milestone and stable which CM follows.

I want to download and flash a build but I'm confused which one to download.

The difference is in the project they are based on (i.e., their parent ROM).

Validus is based on CyanogenMod, Tesla is based on Slim(Kat/LP), Tipsy is based mostly Android Open Source Project (AOSP) with some Slim(Kat/LP).


My Samsung Galaxy Note won't charge but will turn on for 1 second I got my Samsung Galaxy Note about 5 months ago and three months into having it I dropped it and cracked the screen. The actual touch screen works it is just the glass that is broken. About a month or so after having dropped it I started using my mum's phone for a while, as the size was starting to be a problem and I was about to go to a festival. I have come to want to use my Note again and it hasn't let me charge it. Is this because of how long it has been since it was last charged or the strength of the charger that came with it? Or could be be something to do with the screen?

Yes, it can be because of so long time of charging. You must go for service center so that problem can be solved systematically.


Root Nexus 7 with 4.2.2 I'm trying to root a Nexus 7 with Android 4.2.2 (1st generation). I am following instructions here:
http://honai-android.blogspot.com/2013/06/how-to-root-nexus-7-on-android-422.html?showComment=1377379346836#c8791363668077143555
I get to Step 4 in which it says to wait until windows has finished installing drivers. I am on OS X. The Nexus 7 is in fast boot mode. It has an image of the green Android lying on its back with a panel open, in the upper right is "Start > corresponding to the on/off button" and just below that up and down arrows corresponding to the up/down volume buttons. I plugged in the USB and nothing happens, ie no indication of drivers being installed.

I watched this video:
http://www.youtube.com/watch?v=V0MyTvgfO7s
Which was somewhat helpful. Following the instructions enable me to see that the Nexus 7 was connected to the Mac in fastboot mode.
So I continued on to step 5, Running root-mac.sh resulted in this error in the terminal window:
... FAILED (remote: (Nv3pBadReceiveLength))
downloading 'boot.img'... FAILED (unknown status code)

Then from here [GUIDE][MAC/PC/LINUX][4.2] Unlock, Root and Flash Recovery at Android Central (sorry it won't let me put 2 links), I did the commands:
./fastboot-mac oem unlock
./fastboot-mac oem reboot

It did a clean install and reboot, but it is not rooted. When it was rebooting, the padlock icon was showing that it was unlocked. I test for root by trying to run the app Z-ScreenRecorder, which required root access.

I got it. After the unlock and reboot commands, then I went back to the original instructions and ran CF-Auto-Root-grouper-nakasi-nexus7/root-mac.sh.
Now the Z-ScreenRecorder app starts.

If you want to unlock the bootloader, root and add a custom/stock ROM, then you want to use Wugs Toolkit for Nexus. (Try to borrow or use a Windows PC or laptop, its not for OS X)

Here is XDA forum link:
http://forum.xda-developers.com/showthread.php?t=1766475

Here is the download link (this is for Windows, not OS X)
http://www.wugfresh.com/nrt/

Its pretty self explanatory, but try to read it all anyway.

As far as I know there isn't a version for OS X

I have used this method on my 2 Nexus 7s and my friends Nexus 4 & 5!!!

Happy rooting everyone!!!!


Do refunded Google Play purchases show up on credit card bill? When you purchase an app that costs money on Google Play but then refund it within the 15 minute leniency period, does any record of the purchase and subsequent refund show up on the bill from the credit card you used to make the purchase? If so, what would show up on the bill?

I don't get any refund on my credit card statement. Nor do I get a debit to begin with for the initial purchase.

The payment is probably held for the fifteen minute refund window. Chances are the actual payment run from Google to the financial institution is done in a batch or a few batches throughout the day. The specifics of the transaction run is down to Google and their bank(s).  I'd imagine they send the debit leg of it after the fifteen minutes from your account and credit an internal suspense account and then send out the batch during the day as I said.

That's only a rough guess but I have worked in software testing similar payments in financial institutions for a long time. It may vary in different countries, I'm in Ireland but I would like to see how it works in other regions.

If, hypothetically you did see a refund for any purchase like this you would see a debit for the purchase and a corresponding credit to your account for the refund with some reference to the app, music or whatever you have purchased.

On the Sony Xperia Z5 Compact, seems to be this file SD-Card/Android/data/SonyBnR/Backup


Samsung Galaxy S in boot loop after following cyanogen mod's full update guide I have been following this guide to root my Samsung Galaxy S smartphone. I've followed it to the letter, but after I load the new kernel to the phone, the phone gets stuck in a boot loop. The phone restarts after the kernel is loaded, it gets to the "Galaxy S" splashscreen, and then it goes off and restarts. Nothing else happens.

I have tried to get in to the recovery mode by holding the power, home and volume up button, and all this seems to do is hang the phone when it displays the same splashscreen. It does nothing else.

I'm really stuck, I've tried reloading the kernel several times since but nothing happens (I can get in to Download mode). I've also read on another forum that you can press the power button and the volume up and down buttons, but these don't do anything.

Many thanks for the help!

Edit
Honestly, I am not 100% sure that this was really a problem related to the kernel. I think that the "problem" could be also caused by the fact that pressing the home key in recovery mode results in a reboot. The correct way to select a recovery item is to press the power button.
Original post
I had the same issue two days ago. The problem was the kernel. After switching to the kernel that was mentioned a few wiki changes before it worked like a charm.
Kernel: http://cmw.22aaf3.com/aries/gt-i9000/root/Hardcore-speedmod-i9000.zip

wifi issue on samsung- galaxy-s-duos My mobile device doesn't detect any Wi-fi signal even though there is an active network available in the area.
Can anyone help me to find a solution to this problem??
Device: Samsung galaxy-s-duos.

The best thing to do is to try to restart your phone. Check your settings and make sure everything is on in the wifi settings.

Keep in mind that if the wifi network is hidden, it won't show up - you have to manually enter its name and password to be able to connect.

Switch off the tablet
Press the volume up key and power key at the same time
After 15 seconds, the screen will turn on, showing "no command" and the Android logo
Press the power key, and then the screen will show some options
After keeping mind instruction given on the screen, go down and click on format and wipe all data, then it will show the process
Reboot the tablet
Complete the tablet's profile
If there's a problem of entering a wrong email address, enter the email address which was entered the first time in the tablet, and then you will be able to get access to the tablet.

Keep in mind that the whole tablet's data will be deleted when following this process – so first, back up all data after connecting the tablet with any secure PC.


Why root makes phone fast I have heard many sites saying that  rooting makes phone faster but in technical detail it just increase process and more process = slow phone so why people say it

Example : we have phone   A  and phone  B   A  is rooted and  B  is not but   A  runs without any root apps so which will be fast (according to sites A will be fast)

There are several ways that having root may improve performance. But just rooting won't make a phone faster.

One common thing to do with a rooted phone is to remove "bloat" apps. These are apps that are installed by default. In recent versions of android, you can "freeze" or "Turn Off" more built-in apps, making root less of a requirement for de-bloating. Here's a guide for those without without root. With root, your best bet is to find a guide in the specific forum for your phone on XDA Developers or a similar site. These will include other users' experience about what is safe to remove or disable.
There used to be a lot of types of apps that could tune the memory management with the goal of improved performance or longer battery life, but I haven't seen them recently. Modern phones often have a lot more ram (2 or more GB) than they used to.
Another thing that a rooted phone with a specific kernel can do is overclock the processor. This is complex and potentially dangerous (could crash or cause physical damage to the phone by overheating), but may be useful for older phones with slower processors.
Installing a custom ROM may also make the phone run faster, depending on a lot of factors about the specific phone and the specific ROM.
There are also many specific fixes for individual phones that can improve performance.
Ad blockers can speed up web browsing (as well as make the phone more secure). Most of these require root as they install hosts redirects, although there are some that appear as a VPN and should work without root.


Contacts synchronisation I synchronized my Samsung S2 with mail Exchange account, and downloaded my contacts from Exchange server, but now I want to upload my contacts to my Gmail account. In my Gmail mail app I created new account but when I click sync my contact, nothing happens, no contact were uploaded to my Gmail acoount.

What to do ?

There are many ways to sync your Exchange contacts to Gmail.  The easiest way is to do this on your computer.  This involves exporting your contacts from Outlook into a CSV file, and then importing that file on https://mail.google.com site.

Export your Outlook contacts to a CSV (Comma Separated Value) file.  Steps to do this vary for different Outlook versions, so search your Outlook's help for exact instructions pertaining to your particular version (e.g. Outlook 2010 instructions are here.)
In your browser open Gmail, and navigate to "Contacts" section (click on the "Gmail" to reveal the drop-down.)
On the main Contacts screen click on More button and select the Import... option.
Click the "Browse" button in the "Choose FIle to Upload" window, and navigate to the folder where you saved the CSV file from step 1.
Click the "Open" button, then select the "Import Contacts", and the contents of the CSV file should import to your Gmail account.
Either wait a bit, or manually force a sync via Settings -> Accounts & sync screen on your phone.


Are Foxfi and PdaNet+ simple usb tethering enablers? I Was just thinking why the FoxFi on play store is a little bit expensive.Does  it just enables the USB tethering from  settings does it have something special or a simple USB tethering?

FoxFi enables WiFi Hotspot on your Android phone, with no tethering plan or rooting required.

Recently FoxFi has been merged with PdaNet+ and still offers extended features to enhance tethering. it is also equipped with additional features such as Bluetooth mode and Wi-Fi direct options in addition to USB tether.

The reason its unique is that it enables users to bypass tethering block especially with certain ISPs such as Sprint Boost Mobile or AT&T without needing root or complex workarounds and such features don't come out cheap.

  You can connect your tablets, computers or game console with WPA2
  security. FoxFi usage is covered under your phone's existing data plan
  and secured with WPA2.

If you don't have any tethering block, I guess there is no need to purchase it, rather use the built-in option to tether, or find some alternative gratis software

Media Player starts playing when I unplug headphones The stock media player on my phone has an annoying behaviour. Whenever I unplug the headphones, if the media player is paused or not running, it immediately starts running and playing my playlist. This is very annoying because everyone in the room is forced to listen to my songs until I manage to tap (twice) the Music Widget.

Has this been happening to anyone else? And what did you do to fix it?

Note: I'm not sure if it's Android's stock player or if it's Motorola's stock player, it's just called "Music".
Note 2: From the comments, it seems this is Android's stock music app.

Motorola-Milestone, firmware 2.1-update1.

This is a known bug in Android (even in certain Eclair systems).

There's a widget called Headset Blocker that when added to any of your homescreens and activated prevents the music player from playing whenever you unplug your headest. Freeware and it works. See if it helps.


Connection Timeout on Google Play I have a brand new ASUS Transformer Prime tablet running ICS which I have been using for the first time over the last few days.

I can access the internet without issue using the email, Gmail, browser, YouTube apps, but not Google Play. When I try to use the Google Play Store app it shows a "loading..." message for a few minutes and then stops with a "No Connection" message.

Any ideas how I can fix this?

I was on the verge of packing the tablet up and returning it to Amazon and thought I would try one last thing. I took the tablet to a friends house and tried it on their WIFI just to double check it was not my network. The table worked first time and I used Google Play to install a number of apps.

I then took the tablet back to my house and Google Play continued to work and I installed some more apps.

I have no idea what my router was blocking that prevented Google Play from working but it seems fine now. If the problem returns I know the issue is with my router now, not the tablet.


Metered wi-fi connection on Android tablet? I have a non-rooted Nexus 7 (2013), and connect to the internet via a Mi-Fi hotspot.

I have a low data cap, so I need to track usage closely. I'd like to be able to mark my connection as metered, but since this is a tablet, those options don't exist in Data Usage.

Is there any app or alternative method to enable that functionality?

At least on my Nexus 10:

Settings → Data Usage → ⋮ menu → Network Restrictions

brings up a screen where you can set whether each WiFi network is metered or not.

What's causing the pictures copied to my HTC Desire to disappear? I'm currently running CyanogenMod 7.0.3 on my HTC Desire, and pictures copied to the SD card disappear!

If I copy an image from my computer to the phone using USB Mass Storage mode, it disappears as soon as the copy is finished.

Pictures taken with the Camera app disappear too.

Pictures copied with adb push some_pic.jpg /mnt/sdcard/DCIM/100MEDIA don't show up in the Gallery app.

I noticed a similar problem on my HTC G2 recently after I migrated phones.  Deleting the thumbnails folder fixed the problem.

Music playback stops when the phone sleeps I got a new Sony Xperia V (LT25i). When listening to music on the phone it stops playing music as soon as the phone goes into sleep. I have tried both Walkman player and 3 and both give the same problem.

Clarifications:

I play from SD card and internal storage.
It is a new phone, there is no app killers running that I know of.

If you're streaming music via your WiFi connection, you might wish to check your WiFi settings, and there go to "Advanced settings". Here is defined how WiFi should behave when the phone goes to "standby". The default usually is to disable WiFi, so you might want to set it to be kept alive:

While screens might look a little different depending on the device being used, these screenshots should help you identifying the settings :)


How do I connect my Galaxy Y GT-S5360 via USB to my Mac? I cannot connect my Galaxy Y phone to my MacBook for mass storage using a USB cable. I have installed Android File Transfer software but it does not detect my phone when I connect it. I believe I have to change the USB / Mass Storage settings on my phone but cannot find them in the Settings. I have disabled USB Debugging in Settings > Applications > Development but there is no USB setting in Wireless and Networks. Where do I find the USB Mass Storage settings in my Galaxy Y phone?

Any time if you connect your android mobile device to a laptop/desktop, you just switch over to "Notifications" and select the option which is for Connecting your mobile phone to devices. Click on the 'Connect to Storage' option.


Can't find settings for restricted profiles I have a new Asus Memo Pad 7 with Android 4.3 installed and I want to add a restricted profile, though I can't find the menu to do it. On the Google Support page it says it's located in Settings > Users > Add user or profile but I don't even have a Users section in the settings app.

What am I missing?

The reason I want restricted profile is that I want to restrict the tablet to a single app and require a password to exit the app and after some searching it seems like restricted profile does just that, right?

I presume that you have root and got a terminal emulator installed. These are the steps you need to do:

Su
pm get-max-users
setprop fw.max_users 8

Now the users section should be visible, if it isn't make a user account like this:

pm create-user user_name

Hope my answer helped.


Is it possible to get my headset to initiate a recording app and record my voice? I have a set of Sony headphones with a single button and microphone. I also have a Samsung SC-04F running Android 5.0, unrooted.

I want to be able to press the button on my headset once and record my voice. When I press the button again, the recording stops.

Ideally this can happen regardless of what ever other app I happen to be using. So, if I'm listening to music, pressing the button will start the recording app. I guess it should probably pause the music, and then ideally return to music playing when I stop.

I've looked at options for apps that claim to allow recording via the headset microphone. But, this one for example, seems to require that the app already be running. I've also looked at headset button control apps, and I can get it to open a voice recorder app, but not actually start recording.

Is what I'm trying to achieve possible?

I can't say too much here, but this thing may be achieved by an app called Tasker. Many users say it god of android. To function on every aspect of requirement, it needs root access. In your case, it does not require root access.

You can use its capability to achieve that certainly. This is wiki page of that app.

Edit :
As OP said that he has hands on Headset Button Controller. This app is also supports tasks created by Tasker app.
Steps to Achieve this ->

  Open Tasker App. Go to Tasks tab. Click Plus(+) to add a task Record. Now edit the task to get it function what you want.
  Click +, then click on Media , then Record Audio.
  Give the file name of your recorded file. Select your source ( In this case Microphone). You can select format on your choice.
  Now link this task with that app. Open app. Click on one of interaction that you want (Single click is your choice in question).
  Now choose Tasker task and select the task (Record) as you created in Tasker app.
  You are good to go. Try it.

I tested it by myself. So, it must work. On more out of Tasker, use WiKi as posted above.


Data Recovery on non-rooted Samsung Galaxy Tab 10.1v a friend has deleted some photos from her Samsung Galaxy Tab 10.1v (GT-P7100) using the Gallery app. While the app's automatic backups were activated, she had never used the Google+ app before, so my understanding is nothing was saved in her Google account.

I tried to use a data recovery utility, namely PhotoRec, but from what I have gathered it is unable to see the device's internal memory (no SD card in the GT-P7100) as a disk, as the Galaxy Tab 10.1v does not connect as USB Mass Storage but uses the MTP Protocol. So, no luck using such a tool directly.

I found a guide on XDA-Developers that deals with this problem: here. It extracts a full disk image from the device, which could then be analyzed. However, the guide requires your device to be rooted (it is not atm), and rooting on this particular device requires the bootloader to be unlocked: galaxy tab 10.1v rooting. Bootloader unlocking requires internal memory wipe, and I'm worried that this operation could undermine the data recovery.

My questions are:

Does anyone have any experience using data recovery tools with a MTP-only device? How would you go about it?
Will wiping the Galaxy Tab's internal memory undermine the recovery operation? My guess is yes, and I'd rather not root the device at all if my chances to recover anything are grim.

Thanks everyone!

This might or might not work. Insert an SD Card, preferably more than 4GB.

Boot into android stock recovery.

Power + Home + Vol. Up

Scroll down to backup internal data.

Remove the SD card.

Go through the steps of unlocking the boot loader but don't flash a custom recovery yet.

Reboot into recovery(stock) after unlocking the boot loader. Restore user data.

Flash a custom recovery. Root your device. Then go about what you we're trying to do.

How to flash Samsung devices from a GNU/Linux host running on ARM architecture? To flash a Samsung Galaxy S (where do not have root access in the currently running OS, and with a stock recovery) with a new firmware (OS), I need to connect it with a USB cable to another computer and flash it from there.

There is a further problem if the other computer (which runs a GNU/Linux, Ubuntu) is ARM (it's a Toshiba AC100). So to flash a new OS onto the Samsung Galaxy S through the USB cable from the other computer, I'd need something like heimdall for ARM. It's not among the available pre-built downloads for heimdall. Perhaps, I will have to try to build it for ARM then...

Is obtaining heimdall for Linux on ARM possible?

ARM is currently not supported officially by heimdall.
You might have luck compiling it yourself:

https://github.com/Benjamin-Dobell/Heimdall/

My advice however:
Use a supported platform once (Win/Mac/Linux-x86/x64) and enjoy on-device updates from then on via ClockWorkMod recovery (CWM) or RomManager.

Reason: Heimdall is only needed to install a bootstrap CWM once. After that you use the regular CWM.

Here's the guide from cyanogenmod:
http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide

CyanogenMod releases for CM7/9/10 in various flavours (stable, release candidate, nightly build) can be found here (Galaxy S i9000):

No system updates for Galaxy Nexus (maguro) with Cyanogenmod 11 after 20140225-SNAPSHOT-Installer I have a Galaxy Nexus (maguro) and some time back I got an OTA udpate after I installed Cyanogenmod on on the phone using the installer. I'm not sure which 'M' release this OTA update is. All it says in Settings >  About phone > Cyanogenmod statistics > Preview data is the following:

  11-20140225-SNAPSHOT-InstallerXNPQ09P-maguro

I'm assuming this is an update added on 25-Feb-2014.

But in the Cyanogenmod download page for maguro (https://download.cyanogenmod.org/?device=maguro), it shows 'M' releases that were added way after that, like M6 added on 04-May-2014.

So, 1) Why am I not getting these updates through Settings >  About phone > System updates and 2) Why doesn't the above mentioned snapshot show up in the Cyanogenmod download page for maguro?

Many thanks!

The answer to 1) is:
The installer doesn't use the same releases as you see on the download page, it has separately signed releases so they're not directly comparable. Sorry I don't know how you can predict when you might next get an update when you've used the installer.

The answer to 2) is:
Latest release for installer devices are here: http://wiki.cyanogenmod.org/w/CyanogenMod_Installer#Supported_Devices

For the galaxy nexus that is:

  11.0-InstallerXNPQ09P

Further info:
On that same wiki page it says:

  How do I get updates?
  Updates are done via Settings > About phone > System Updates. When a new snapshot build is >available, your will also receive a notification. Devices flashed via the installer will only get updates when a new stable snapshot build is available.

I suspect that might be out of date however.

The following seems to be the most recent up to date information:
http://www.cyanogenmod.org/blog/cm-11-m4-post-release-items

  Installer builds are those served via the CM Installer applications (Windows, Mac). These >builds are specially signed and named separately – there is no concept of an ‘M’ build for >this release channel – so saying ‘Installer skipped M#’ is an incorrect interpretation. >This channel only ever receives specially created Stable builds – they even come with their >own naming structure (eg XNPQ02R).

There is an additional blog post that rehashes some of the information on the m4 blog post above with a bit of extra clarification here: http://www.cyanogenmod.org/blog/cyanogenmod-11-0-m6-release

How do I separate contacts from work and personal Google accounts? I have two Google accounts, one for work and a personal one for my Android phone.

I have both accounts synced to my phone because I often have work to do on the road. I recently noticed while logged in to my work account in GMail that all of my personal account's phone contacts appear in my work account's contacts. I never asked to have the contact lists merged together, nor did I add one to the other.

They may have been logged in together on a computer at one point before, but I can't remember. My personal account is not currently logged in on the same computer as the work account, so I'll be able to delete them from the list now. I just don't want this to happen again.

Is there a setting to suppress this behavior?

You can download Google Contacts app.

When you want to switch accounts, just tap the profile picture thumbnail on the top right, and select the desired account.

You can select either Google account, or view an unified list (for whatever reason, or if you later change your mind)

When adding a new contact, make sure that you are selecting the correct account. (you can view it at the top as Save to)

Of course, both accounts need to be connected to the device, and sync should be enabled.

And if you mixed up your contacts...

From your comment:

  [...] it seems that the phone's contacts are syncing to both accounts. [...]

You can switch accounts to confirm, and if it happened, you may want to delete the duplicated contacts, and then switch to the other account and move your contacts to the right place.

Select the contacts you want to move (tap and hold)
Press the menu button (or the three dot menu at the top)
Select your desired action:

Select all
Delete
Move to another account
Add label (Group using tags)

For more details, you can visit the google contacts support site.


Is there a fitness app which can record my workouts across multiple activities? I've been using MyTracks for tracking my running, and another app (which I forget the name) to record my cycling routes.

I also do gym, swimming and karate, is there an app which lets me keep track of my fitness workouts across multiple activities? I.e, I don't want to have an app for each one, its annoying.

I'd like to record things like time spent training, lengths/laps (for swimming), possibly bike/rowing/treadmill times/speeds/distances for the gym etc.

This will allow me to track myself over a period of time and see how much I've increased the duration/effort in my training.

Any suggestions?

Try out Cardio Trainer.

It is able to record many types of workouts including walking, running, weight lifting, swimming (do you rely on your water-proof case?), yoga. You can also prepare your own custom routine (never tried that, but in your case, it might come handy).

Phone evicting inactive applications from ram, despite plenty of memory free The phone (Jiayu G4S) is running Android 4.4.2, 2GB of ram, stock jiayu.es rom (kernel 3.4.67)

Stock configuration also sets up some swap in zram, I disabled it, does not seem to make a difference.

Task manager shows at any time at least 0.92GB free or more. It shows at most 12-13 cached inactive apps that are still in ram, a bit more if process limit is manually set to a high value (just for kicks I choose 100).

According to dumpsys meminfo, this is how it looks now:

Total RAM: 2016644 kB
 Free RAM: 883420 kB (230000 cached pss + 131652 cached + 521768 free)
 Used RAM: 852001 kB (805401 used pss + 1684 buffers + 8972 shmem + 35944 slab)
 Lost RAM: 281223 kB
     ZRAM: 4 kB physical used for 0 kB in swap (0 kB total swap)
   Tuning: 256 (large 512), oom 122880 kB, restore limit 40960 kB (high-end-gfx)

And yet, frequently used applications get periodically thrown out from memory (shown in task manager with 0.00b allocated), which results in a small delay at next launch.

oomkiller parameters seem sane

shell@G4:/ $ cat /sys/module/lowmemorykiller/parameters/minfree
12288,15360,18432,21504,24576,30720

Why are frequently used programs kicked out, despite all that free memory? Is there anything I can configure (I have root access)?

And now to answer myself. Looking at Android 4.4.2 (KOT39H) sources, in ProcessList.java we have defined a maximum number of cached apps, set to an arbitrary value of 24:

static final int MAX_CACHED_APPS = 24;

This value is further split as follows by computeEmptyProcessLimit function: 2/3 goes to empty process limit and 1/3 goes to cached process limit.

So now we have an arbitrary limit of 16 for empty and 8 for cached processes. (But go buy a 3GB ram phone, to see how much unused memory you'll have)

In stock android, the only way to change this limit is at runtime, via setProcessLimit(), which requires rooted phone, an application manually installed in /system/priv-app and the SET_PROCESS_LIMIT permission granted.

(In CM11 for example it can also be set in build.prop, but this code is not present in stock 4.4.2)

Luckily there already is such an application on github, called SetAndroidProcessLimit, which, installed correctly, works (my thanks to the author)

Now I have 20 cached apps in ram, that's about all apps I frequently use, and any of them will start instantly, zero delay.

I also figured out how to modify MAX_CACHED_APPS directly in /system/framework/services.jar

download the jar to your pc, unpack the jar
decompile classes.dex with baksmali (or via apktool)
modify in ProcessList.smali and in ActivityManagerService.smali - because this is bytecode, you have to replace not only declaration of MAX_CACHED_APPS but every occurence of it with new desired value
recompile classes.dex
repack the jar
download to phone, replacing original jar (you have to remount rw /system)
reboot the phone; mine automatically will regenerate dalvik cache


Unlocking an HTC desire 510 phone In this tutorial is the method I am currently following to unlock the bootloader.

Just before Step Four there is a paragraph that says:

"The Command Prompt will spit out a token in the form of a very long string of characters. Select it, copy it, and paste it into the applicable box on your manufacturer’s website–make sure there are no spaces!–and submit the form...."

This is the stage I reached. I cannot however find that "applicable box" after numerous searches! Could someone help me find it? Or suggest a better way altogether to unlock the bootloader?

Have you done the process via DevHTC ? ...

Htc offers a original unlock method here official unlock at HTC site for developers


Email app with HTC mail feel? Is there email app that has the HTC mail feel? HTC mail blocks cryptographically signed messages, which I finally figured out today. Is there some replacement besides K9?

It is for phones that are always on and receive floods of emails for multiple accounts.

I only care about IMAP(s) connections, not MS exchange.

There are email replacement apps, but unfortunately the few that act similar to HTC Mail will cost money.

Touchdown by Nitrodesk: Touchdown is my preferred email replacement as I use the exchange functionality, and imap protocol. It can tie into most major email services, and also offers some premium features for business users.

Enhanced Email: A more powerful revamp of the stock Email app that is starting to become popular.  It offers some premium features and the developer is very responsive if you have run into issues.

Moxier Mail (free trial): Offers support for all major protocols, its user interface is probably the closest to the HTC Mailapp.

Maildroid (free): Never used MailDroid, but it is yet another email replacement.  The upside is there is a free Ad supported version.

Hope those help!


4.2.2 update error on Samsung Galaxy s2 plus GT - I9105P i got a Over The Air update for 4.2.2 on my Samsung Galaxy S2 Plus. I'm in India.
After installing the update my phone rebooted and now it doesn't start. it only loads and shows the samsung's logo.
What should i do now?

I don't think you have installed update provided by samsung.
I am Samsung S II plus owner in India and I didnt get any OTA update yet.

This problem might be due to corrupted ROM. Roll up to the previous ROM it'll work

Cheers!


Move applications to SD card in Samsung Exhibit? I have just acquired my first Android phone -- a Samsung Galaxy Exhibit (SGH-T599N) running Android version 4.1.2 (Jelly Bean).  Because the internal storage is fairly small (only 1.34 GB) I've inserted a 16 GB SD card.  I downloaded the program AppMgr III (formerly app2sd) and attempted to move applications to the SD card; however, when I click on the "On SD Card" tab, I see the following message:

  This device doesn't enable users moving apps to the SD card.  Usually, it's because of the manufacturer removes [sic] the function of moving apps to SD from Android, or a SD card is not inserted.

I see there are many similar threads for other devices, but none explicitly address the Exhibit.  Is there a way (preferably without rooting) to override the manufacturer's removal of this function?

It's impossible to move apps without root if this function is not supported natively. And 'overriding manufacturer's removal of this function' means you are trying to have extra access apart from native support. And that's possible only when you have root access

If you are willing to root your device, you may check this link:

Phone is plugged into computer via USB, charging but not entering adb mode I am on Linux, so this is not a driver problem. I have a Huawei Union, USB Debugging is enabled in developer options, and I have previously been able to use ADB when the device is plugged in via USB. The phone displays, "USB debugging is on" in the notification tray, and ADB just works. Now, when I plug in the phone, the phone does not show this notification and adb devices shows nothing. Is this a problem with my USB cord or one of the ports on the devices? Because it worked just fine when I got all three parts (the laptop, the phone, and the cord) two weeks ago.

Are you using the usb cable that came with your device? Check another usb port on the laptop, reboot the laptop if another port doesnt work either. If that does not help, check another usb cable. Good luck.


My data is wiped out after a battery service I hit my Nexus 7 with Android 4.2 on it, into a glass bottle. Somehow, internally the battery got disconnected so it didn't turn on. It was only flickering a black screen when attached to a power cord. I didn't want to fix it myself so I brought it to a certified service for mobile devices. I received it back but it had installed Android 4.4 and all of the data was wiped out.

What did the people from the service do to my Nexus 7?

Sounds like they just replaced the device and gave you a new/refurbished one. Your original device will be fixed (if possible), and then it will be wiped and turned into a refurbished unit.

If you didn't back up any of your data, it is gone. Hopefully you did; I'm pretty sure anytime you send in a device for service, they warn you that it could be completely wiped.


Xperia play bootloader locked? Hi guys i've been trying for quite a while to unlock the bootloader of the phone i've bought. It's from hong kong and branded to vodafone it's not sim locked as I tried an optus sim and it worked.

I press and hold the search button and plug the usb in and I get a blue light but when I try to check if fastboot can find it, it can't.

Any ideas what the problem is?

If fastboot from your computer can't find it, try following these steps exactly, beginning with installing the Requirements below. The most likely problem is some sort of driver missing, disallowing the computer from reading the phone in while it's in the bootloader.

This guide can be found on addictivetips.com, and uses a fastboot program from your computer to unlock the bootloader:

Requirements:

Fastboot package.
Sony Ericsson USB drivers (32bit & 64bit).
A functioning internet connection.

Steps:

To begin, navigate to this website: http://unlockbootloader.sonyericsson.com/instructions.
Click Continue at the bottom of the page and enter your device’s IMEI code, name and email address in the relevant fields.
Your unique unlock key will now be mailed to you.
Now unzip fastboot.rar and open the folder extracted.
Within that folder, hold the Shift key and press the right Mouse button. Now select Open command window here.
Now we need to connect the phone to the pc in fastboot mode. Do so by turning the phone off, holding the menu button (search button for the Xperia Play) and plugging in the USB Cable.
Now in the command prompt, enter the following command:

fastboot.exe -i 0x0fce getvar version

Now enter the command, replacing KEY in the string with the unlock key mailed to you:

fastboot.exe -i 0x0fce oem unlock 0xKEY

That is it! The bootloader is now unlocked.


Still stuck in download after uninstalling the app and hard reboot My Android phone (4.4.2) is stuck in downloading an app. I uninstalled the app and removed the battery and rebooted and when it restarts, it's still trying to download the app!

Can you allow certain contacts to bypass the silent mode on Huawei P20 pro? is there a way you can allow certain contacts to bypass the silent mode on a Huawei P20 pro? I like my phone on silent through the night but need to have a certain contact to be able to ring (elderly relative) Not a problem when I had an iPhone but can't find a way on this new phone. Thanks in advance!

You can find that in Settings → Sound → Do not disturb → Advanced parameters.

You will need to define a Priority Interrupt. Use 'Only contacts on whitelist', and add that contact to the whitelist.

My P20 pro is in French. I translated the menu words, though, not sure my wording is 100% identical to the original.


Merge Skype and Gmail contacts I recently installed Skype on my phone, and so all of my Skype contacts are added to the full list of contacts in my phone. However, most of these contacts are redundant. A few of the redundancies were automatically detected by Skype, and so the two versions of the contact are merged together.

But many weren't, and I need to way to manually do that. Right now, I have many contacts that show up double on my contacts list (once for gmail+phone info, and once for skype info). I've been poking around but I can't find a way to manually merge these two contacts. Skype contacts don't show up at my desktop Gmail contacts list. Is there a way to do this?

I'm not positive when it was added, but if you open one of the duplicate contacts and edit it, you can press Menu>Join to collapse two entries into one.


Android Engineering Mode Is there a way to change between User and Eng mode on android devices? More specificity the Motorola Defy (2.2.2) and the Acer Iconia A500 (4.0.3) I need access to tools like dev tools. I dont mind if I have to root the DEFY.

No you cannot, that is done at build/compile of the source of the said Android version whatever that may be.

When the source gets compiled via

. build/envsetup.sh

This is setting up the environment, and that reads in the potential devices via BoardConfig.mk within each device/product directory.

Its when lunch gets executed, the menu shows like this

$ lunch

You're building on Linux

Lunch menu... pick a combo:
     1. full-eng
     2. full_x86-eng
     3. simulator
     4. zte_blade-eng
     5. zte_blade-userdebug

Which would you like? [full-eng]

The above is the example of building the ROM for the Zte Blade, notice how userdebug and eng is prefixed!
