How to get a confirmation when deleting images? I just bought the LG G4 (Android Lollipop) and I'm pretty concerned that there's no confirmation "dialog" or something when we delete images in the Gallery.

Something like "Are you sure?".
Because now when I press the trash button to delete image, I have like 2 seconds to press Cancel if I don't want my image to be permanently removed.

This can be problematic if I missclick on the screen or if I let someone use my phone...

My step-father used my phone quickly just to check-out, he took a picture then wanted to delete it.. Then I don't know what happened but my previous photos were removed. I think he deleted all the photos by tapping too fast?

Well, I searched everywhere and I didn't find anything to have more security at least.

I have a G4, and you're right. The Gallery app doesn't have a confirmation message, just a floating dialog that has an Undo button which disappears after a while.

I'd recommend using another app instead. I use QuickPic. When you click the delete button, a popup with a delete icon appears. It serves as sort of a confirmation message. If you click the button, the picture is deleted. Otherwise, you can just cancel the operation by clicking the soft-key back button.


OneNote app -> Save images from Notebook to local storage is there any way in the Android App to save an image from a notebook to local sdcard except for taking a screenshot which in fact gives me a quality loss, especially on detailed high-res pictures?

Thanks!

On my OnePlus 6 running latest OneNote from Play Store, when I long-press an image, Gallery is listed as an option. From Gallery you can really do virtually anything, specifically, "sharing" to another app. Then you can find a way to save the image.


How to disable WhatsApp notification from notification bar I have iVOOMi Me5 with Android 7.0. I have to stop WhatsApp notifications from the Notification Bar as following:

Try Settings --> Apps(or equivalent to what it is on your device) --> scroll down to whatsapp. You should find notification settings there.


Economist app stuck with old issues This has happened to me repeatedly with the Economist app on Android. Basically the app usually automatically downloads the weekly issue by push notification, but sometimes it simply doesn't do that. When I uninstall the app and reinstall it.. it's stuck at the December 19th issue of 2015.

I figured this may be a date problem, so I set the time manually on my phone.. no luck.

Any ideas? And if someone is to suggest this isn't the right stack exchange site for such questions please tell me which one I should use instead .

I basically connected my android device to the internet using a VPN service (unotelly.. I currently live in Lebanon although when I first registered with the economist.. I was living in Canada).

Connecting via the vpn solved the problem


How do I use a periodic trigger in Automagic? There's an app called Automagic which uses flow charts to create workflows that let you perform custom sequences of actions on your Android (essentially macros, but with an advanced interface for editing them).

Can somebody please explain how to use the periodic trigger?

I've tried using it to kick start a flow, but it never fires. I've ensured that the flow is enabled, I've checked the logs and there's nothing about any problems occurring with launching the flow.

You must enter the time. For example, if you want it to be every 5 seconds you need to write "5s".


How to adjust ringer volume while listening to music? When listening to music on my phone (running Android 4.0.4 ICS), I am unable to adjust the ringer volume with the hardware volume controls. Pushing either of them adjusts the music volume and not the ringer volume.

If I hold down the power button, a menu appears that provides me with the choice of turning off the ringer completely, enabling vibrate-only mode, and restoring the ringer volume to its previous level. However, there appears to be no way to actually adjust the ringer volume level.

Am I missing something?

When an app is playing sound, Android will only adjust the volume for what is actively playing the sound (in this case the media volume). You can manually adjust your sound volume under Settings -> Sound -> Volume

If your ROM supports it, you may be able to enable expanded mode for volume under Settings -> Sound -> Volume Panel Style -> Expandable. This will give you a button to the right of the onscreen volume indicator (when you press the volume buttons). Press that and it will show all the adjustable volume levels and you can change it through there.


RemoteDroid connection problem Has anyone tested the remotedroid app? I tried (on windows xp and samsung galaxy 2), installed both server app and android app, but nothing happens. Are there any more settings I should make? Thanks.

First, make sure you have Java Runtime Environment installed (version 1.5 or higher) and try running the server program from the .bat file instead of the .jar file. Then check your software firewalls if they have blocked the application from acting as a server, and finally check your router for port redirection (UDP, 57110) if you have a NAT setup between your Wi-Fi access point and the machine acting as a server. Also it could be worthwhile to check that the IP of the PC hasn't changed since you checked it last, or if you can make it static.


Cellular data not working since 5.1 Lollipop flash Cellular data stopped working immediately after "upgrading" to 5.1-lollipop OTA (from 5.0.2) on my Nexus-4.  I am seeing the exclamation point in the signal strength indicator at all times, except when Wifi is on and connected. Voice calls work fine. Wifi works fine. 2 hours on the phone with Simple Mobile, then 2 hours back and forth with Google support, and still no resolution. So far I have tried:

Erase and reprogram APN settings
Remove and reinstall existing SIM card (that was Simple Mobile's suggestion, although I think if voice is working SIM is probably OK. I don't have a spare to try right now.)
Turning phone off and on
Reboot in Safe Mode
Turning Cellular Data switch off and on
Turning Airplane mode off and on

The exclamation point on the cellular strength icon seems to follow the exclamation point on the Wifi icon, i.e., both go on and off at the same time--when a Wifi connection is made or broken.  Is it possible that this may be a bug related to an accidentally shared variable between the two?

Google 2nd level support has said they don't have an answer.  They want me to try a new SIM card, which I'm trying to get from Simple Mobile.  If that doesn't work they want to "discuss repair options for the phone."

I've seen some other people with similar problems but haven't seen any fixes or workarounds other than what I've already tried.  Does anyone have any ideas?

I'm back up and running.  Here's what I know at this point.  I'm posting it here because I think many people may experience the same behavior.

After much back and forth with Simple Mobile (note that they share some infrastructure with T-Mobile, Tracfone, etc., so users of those services may be affected as well) they found that my cellular data had been disabled on their end.  Nothing was wrong with my account, indeed, voice continued to work normally, it was just the data that had been disconnected.

I asked why this happened and the 2nd-level support person told me that they are still investigating but one thing that's possible is that a change in 5.1 Lollipop caused something to fail on their end.  She said they have been receiving numerous trouble calls with the same symptoms, all with phones recently upgraded to 5.1.

So, allowing for the typical misinformation that we all get from customer support, this actually seems like it's plausible.  I don't want to spread misinformation, but if anyone else is tearing out their hair with these symptoms, try leaning hard on your carrier to check your line.


S3 mini won't boot up after flashing twrp custom recovery with Odin After a successful root, I tried to install twrp custom recovery, so I downloaded the appropriate tar file and flashed it using Odin, but the device never entered recovery mode when I attempted to, it only showed the Samsung logo and freezed there, but it could boot up normally to the system, so I tried the adb command "reboot recovery", it rebooted and freezed at the Samsung logo again but this time it also did the same whenever I tried to boot up the system, I am sure this can be fixed but I don't know how, Please help.

I have solved my own problem, I downloaded the s3 mini stock rom from sammobile.com and extracted recovey.img from it and tried to convert it to .tar format using some batch that I found on the internet then flashed it using Odin, but the problem persisted, so i decided to flash the whole rom accepting the fact that I will be losing all of my data and messages, for my surprise, the device booted and nothing were lost but the root, everything was intact, sms, contacts. apps and everything!


Unlock your Chromebook with your Android phone I'm using following:

Huawei Nexus 6p with Android 7.1.2 (up-to-date).
ASUS Chromebook Flip with Google Chrome OS (58.0.3027.0 dev
(32-bit)) (up-to-date).

and I'm trying to follow: Unlock your Chromebook with your Android phone - Chromebook Help, however I'm unable to complete step #7 with following message on my Chromebook:

  Failed to connect to "Nexus 6P"

yet through "Notifications", I've got another message:

  Bluetooth device "Nexus 6P" has been paired and is now available for
  all users. You may remove this setting using Settings.

Please advise.

I apologize for not posting an answer in timely manner, however I'm doing it right now (that's the best I can do); As of now I'm using Google Chrome OS / Version 66.0.3359.43 (Official Build) dev (64-bit) and Pixel, (Phone by Google (1st generation)) w/ Android 8.1.0.

I went ahead and removed my Phone from Chromebook's Bluetooth devices and from Chromebook from Phone's Bluetooth devices, now that everything is tidy widy, you can proceed to next step:

under Settings, expand Screen lock (under People), click on Smart Lock for Chromebook (beta) and follow steps.


Lenovo Tablet A1 disable screen lock I have a Lenovo Tablet A1 and don't know how to configure the screen settings as I would like them. I want that after a certain timeout the screen dims, and/or goes black, but doesn't actually lock.

That is, right now if I choose a screen timeout the thing locks and I have to press the top power button and drag an icon across the screen -- extremely inconvenient.

I have disabled Screen Lock, but it doesn't change this aspect. I also installed No Lock, but it doesn't work on this device. So far my only half-success is to disable the screen timeout, but then it runs at maximum brightness the entire time.

I have checked many questions, and done searches, for disabling screen lock. Apparently none of these work on the Lenovo Tablet.


While on call, typing a digit on dial pad doesn't make any sound Since my Samsung Duos phone was upgraded to Android 5.0.2, during a call, when I dial some digits on the numeric pad, there is no keypad tone heard. As a consequence, when an answering machine asks my choice like "press one", "press two", I just cannot provide any choice.

I tried pretty much all settings (dialing keypad tone, touch sounds), with no luck, I can't even imagine why disabling this feature.

Any suggestions?

It is good to know that the problem has been resolved. After my suggestions including "cheat code" did not fix the problem yesterday, I discussed this with a Samsung ROM developer. You may like to consider options based on this discussion.

Firstly, the tones which failed are DTMF tones. These are NOT

User configurable
Affected by app misbehaviour
Custom ROM developers also do not tinker with this as it is a deep feature and they don't need to tweak it for user benefit
Stock ROMs/ upgrades will NOT disable it

As to how this happened is a mystery, but there is always an annoying possibility, that this may occur again. You have three options

Do nothing: If it happens again you can try using these kind of apps (bunch of them on Play Store, Google for "DTMF") DTMF Tone Generator

Any of next two options recommended

Device not rooted

Take backup using Kies
Factory reset
Do firmware upgrade/restore using Kies
Restore data using Kies

Or see this for other ways of taking back up  Full Backup of non-rooted devices

Device rooted

Take  nandroid backup using custom recovery backup
Factory reset
Flash upgraded Stock ROM

Can be downloaded from Sammobile after registration. Make sure you download the correct version and of your region

Photos "self deleted" off Galaxy 3 As I was trying to transfer photos from my galaxy 3 to my mac, one of my albums containing over 1500 pictures deleted itself.  I watched the album count slowly decrease.  Why did it do this and how do I get the pictures back?  The album isn't even in my gallery anymore.

Recover images using Data Recovery for Mac
Step 1: Connect SD Card to Mac and Open Data Recovery for Mac
Connect your SD card to your Mac either with a card reader or without pulling out from your device. And then run iSkysoft Recovery on your Mac from Application folder or any folder you've installed it to. This SD card recovery application supports all popular files systems on SD cards, including FAT16, FAT32, exFAT, NTFS, HFS+, and HFSX.
Step 2: Scan lost SD card files
In the "Lost Data Recovery" window, choose the drive of your Mac OS X system and click "Scan" on top to start scanning removed files from Trash as well as other locations.
Step 3: Preview and recover SD card files
When scanning complete, you will see the window below. On the left is the folder tree, with which you can quickly find lost SD card file if you know the folder name. In the bottom list, click the file to preview and find out whether the file is what you want to recover.
Note : This is paid app there are also also free apps available like mac photo recovery free


Do cache cleaner (or "phone booster") apps actually work? Do apps that clean junk files actually work? For example, an app like Super Cleaner.
It promises to clean residual files and junk files.
My main debate is similar to "Does Android need an antivirus?" I can tell that some cleaners make my phone seemingly fast, I just don't know if it's needed, funcitonal or even safe. I've heard that some delete important files, while some don't.

I can say, in my experience that it is truly contingent on the tool you choose to use.

I am very happy with SDMaid, which i have used for years. It seems to clean everything it says it will.

If you read through my other postings here, you will find I usually recommend it for the "CorpseFinder" functionality to clear remnants of older, non-fully uninstalled apps, though the AppControl, SystemCleaner, and Databases functionality are useful, too.

I am satisfied each time I use it that the cleared item were non-critical, yielding back space I can use. I have not encountered a problem with either my phone, or my tablets, where files were improperly deleted, that I would attribute to some actions of this software.

DISCLAIMER - I am not the developer, or attached to the product in any way, except as a satisfied user.


How do I back up SMS without using (broken) touchscreen on Nexus 4? I have a rooted n4 with USB debugging enabled. The touchscreen is smashed, totally. There is an image on the screen, but it is not possible to enter any commands via the touchscreen. The device otherwise works normally. I can see what's on the screen, it connects to the wifi, etc.

So, for example Ritesh SMS backup won't work, because it needs me to tap commands on the phone. I tried the following solution
https://stackoverflow.com/questions/12266374/backup-full-sms-mms-contents-via-adb

but it won't work because the phone pops up saying 'do you want to give adb shell su permissions', I can't tap yes as I can't tap anything...

Note for Non-Nexus 4 users: if your device supports OTG, buy an OTG cable (comes very cheap) connect  a standard PC mouse  and the device to it and use the mouse to navigate the device.

Since the USB debugging is enabled and authorized, you can make good use of KeyEvents. Use input command to simulate up, down, left, and right navigational turns and enter.

Command:

adb shell input keyevent KEYCODE          # adb shell input: give further options

Examples:

adb shell input keyevent 22                # navigates one block rightward
adb shell input keyevent KEYCODE_DPAD_DOWN # navigates one block downward
adb shell input keyevent DPAD_LEFT         # navigates one block leftward

Relevant key codes:

19 -->  "KEYCODE_DPAD_UP"
20 -->  "KEYCODE_DPAD_DOWN"
21 -->  "KEYCODE_DPAD_LEFT"
22 -->  "KEYCODE_DPAD_RIGHT"
23 -->  "KEYCODE_DPAD_CENTER"

(See more key codes here - by Rene Barbosa)

To simulate ENTER, use key code 66. 23 works too.

Use the key codes in combination. For example, when SuperSU app asks me to allow or deny root privileges to an app, I use the key codes 19, 20, 22 and 66 to simulate a tap on OK.

You can always use adb shell input tap X Y but you need the correct X and Y coordinates for the tap. You'll have to enable Pointer location under Developer settings as first step. Since the touchscreen is not working, finding the right coordinates is a hit and miss here. You would succeed with trial and error, should you choose this method.


Factory reset doesn't delete everything I tried to perform a factory reset on my phone to give it to a friend of mine. However, I realised that when I installed Whatsapp, I can still have my chats, my photos and songs aren't deleted as well. What is wrong with this?

It looks like your /sdcard partion is not getting wiped. You need to specify more information but I'm assuming you're using a Custom Rom or at least, a Custom recovery. A stock recovery will as far as I know wipe /sdcard too. Only a Custom ROM by default wouldn't do so. So there's nothing unordinary here. Boot into recovery (I can't tell how since you didn't mention your phone's model) and you can use the options there to wipe any partion you want.


How to use 2 sim cards & SD Card? I have xiaomi redmi note 5 pro, and the sim tray has a hybrid configuration, Either using 2 sim cards or 1 sim and one micro sd card.
Is it anyway to use 2 sim cards and a micro SD card in the same time?

It is not really possible to do all of this in the phone, but you could insert both sim cards to the phone and use an SD to USB adapter.


Update to 4.1.2 on a Nexus S with CWM and broken USB port I have a Nexus S, rooted, with CWM and a stock 4.0.4 ROM. The USB port is broken(only charging works), so how do I go to stock 4.1.2 update?

If there is a way to manually apply OTA, that'd be great. Or a way to fix the USB port, but I think that's widely reported and not really fixed.

I tried the system > updates (and clearing Google services framework trick) and it shows upto date, ie. no new OTA. Perhaps because I have a custom recovery?

If you can find someone else with an unlocked Nexus S, you can use nandroid backups to do everything on their device and then duplicate efforts to your device, like so:
Let's call your phone Device A and theirs Device B.
Boot into recovery on both devices, then make a nandroid backup of each device, which I will call Nandroid A and Nandroid B, for each phone.  Using some sort of wireless file-transfer application (AirDroid, Samba Server, etc), transfer the nandroid backups to a computer for safekeeping, and then put Nandroid A onto Device B and boot into recovery on Device B. Wipe the cache, dalvik cache, system partition, and data partition, then restore Nandroid A onto Device B. Once the restore is complete, boot Device B normally and perform the OTA update as you would under normal conditions.
Reboot into Recovery on Device B after installing the update, and make a new nandroid backup which I will call Nandroid A2. Then, move files around wirelessly as outlined above and wipe Device A and restore Nandroid A2 to Device A. Finally, wipe Device B and restore Nandroid B to Device B and give it back to your much-indebted-to friend.

Be careful when you wipe before a restore /not/ to wipe the internal storage on the device. The Nexus S doesn't have an SD card slot, otherwise I'd just advise you remove the SD card altogether while restoring... But TWRP has a pretty straightforward checkbox that will help you make sure you aren't wiping your internal storage.

Yes, this method is roundabout and long-winded, and yes, it does require access to hardware that you may not be able to get your hands on. But it will work.


How can I make new/separate folders in the gallery? I recently had some issues with my LG Marquee and had to copy the SD Card's contents to my PC, then put those contents onto a new SD Card to salvage my media content(photos, videos, apps, etc.) When I inserted the new SD Card with my content on it, my phone took the content but it all (all 3,548 items) were placed into one single folder in my Gallery.

My question is: How can I separate/organize these items into new and separate folders in the Gallery?

Is there a specific way on my phone that I can do this, or do I need to download a photo organizing app? If so, what photo organizing apps are safe and secure?

Thank You!

My work-around is connect my phone via USB mode, where it comes up as a folder (or volume for you Mac fans) that you can see contents in. Create folders you'd like to have in your gallery, like "Favorite Piks" or "Stuff I found in my pockets" - whatever. Put these in that folder.
Now use your computer to organize the images between folders within that main volume, save on your home computer, delete, so forth.
When you detach from the USB link, your gallery on the phone should show those new folders you created and the images you transferred over.
Please note that any NEW images, photos you download or take with the phone will likely be placed in one of any generic folders like "Downloads" or "Pictures".
t0mm13b's Edit
Pre-requisites:

ADB is installed.
comfortable with Command line.

By going onto the command line, and issue this command:
adb shell am start -n com.android.development/.MediaScannerActivity
The above command line will force Android to re-read the SDCard and quickly re-index all the just transferred pictures into the Gallery.


Fast way to update custom ROM on encrypted phone? If I add corporate (exchange) account to my phone I am forced to use PIN and now it even forces me to encrypt the phone. I have not done it yet but I need to.

I udate my ROM - cyanogenmod - quite often. Now I have no idea if I am going to be able to do so and if it process of updating is going to take longer.

HTC One XL phone - no external SD card
TWRP recovery
I use Titanium Backup to do backup before update and then restore after update.
Currently I am running CM11.2 but want to try cm12 soon.
Q1) can I still use Titanium Backup to backup/restore?
Q2) How to quickly update cm in future if the phone is encrypted?
Q3) enything else I need to know before I encrypt the phone?

It depends a bit on the recovery you use. But if your device has enough RAM, you could try to install the update via adb sideload.

If you encrypt "your phone", actually only the data partition gets encrypted. You can use Titanium Backup to back things up, but you will be out of luck regarding the data partition (and possibly internal sdcard, see below). If you use TWRP, it offers the option to unlock your encrypted /data when entering recovery, making a full backup possible. Also, using such a USB-OTG device allows you to update via ZIP directly from there!

Depending on your device, also the internal sdcard (and/or external - but you don't seem to have one) will get encrypted. In this case, your recovery will be unable to store the backup anywhere, but if you encrypt your phone you certainly don't want to store your backup unencrypted somewhere on the phone. Therefore, if your device supports USB-OTG, you could just connect an unencrypted usb stick for this purpose - this would be my recommendation.

Apart from that, you can always do "raw" backups directly via ADB by backup up unmounted partitions or even complete block devices. You should be familiar with the partition layout of your device in this case, or simply backup the complete flash (which might take a while). You would typically achieve this (just an example, you might have to use a different device name!):

adb pull /dev/block/mmcblk0

And to restore the backup:

adb push your-backupfile-of-mmcblk0 /dev/block/mmcblk0

But of course you can do this also just for individual partitions, e.g. /system:

adb pull /dev/block/sd.whatever/by-name/System

Check out the fstab.VENDOR file for your device (typically resides in your root directory), you should be able to find the proper device names in there.


samsung galaxy s duos s7562 update is not installing I have Samsung Galaxy S Duos S7562 and recently received a notification about Software Update so that i proceed to install but update is not installing my mobile.

I tried using Kies also and getting the same result.

Note: I rooted my mobile and i disabled few services.

so i need to know, Is there any service should be running to install updates?

Generally, official over-the-air (OTA) updates from Google/carriers/manufacturers will not install on rooted devices, especially if you've changed something on the /system partition.  The update usually checks if the device is in a given state, and won't proceed with installation if it detects tampering.

If you want to accept the OTA update, you will first need to bring the phone back to its original state.  This means undoing whatever modifications you performed, and un-rooting it.  After updating you should be able to re-root.


Samsung S4 and Kies error I am trying to connect my Samsung galaxy S4 to Samsung Kies, yet it says it is not compatible and to download Kies 3 - which I did and then it says the device isn't supported - so both versions of Kies won't work - any ideas its driving me mad :( I have uninstalled and re-installed several times.

thank you

Is the phone in Odin download mode? If you connect the phone when it's in Odin mode, Kies detects it, but gives you exactly those messages. You can't use Kies with Odin, it only works when the device is booted. To use Odin, you need the Odin desktop app for Windows.


How can I monitor bandwidth capacity over time? I know that I can use some applications such as Speedtest to check my current bandwidth capacity. However, I would like to monitor bandwidth capacity over time as I would like to assess the quality of the wifi connection around me throughout the day. Is there anyway to do so on Android?

I use Samsung Galaxy S3 with Android 4.1.2 and Nexus 7 with Android 4.4.2.

That's a pre-destined case for apps like OpenSignal, which are designed for mapping signals around you. Network Signal Info offers it as well. Both tools can be used to get a coverage map for WiFi and mobile signal, and also offer you to log signal strength.

Video streaming from PC to Android? I just installed Opera Unite's video streaming service. I can access my video files through my phones web browser (Galaxy S), but it starts to download instead of playing.

Is there a player I can use to watch streamed videos from my PC?

Non-root Option

Subsonic

Subsonic is a free, open source, web-based media server in Java. It is easy to install and runs on various platforms. There is also a Subsonic Android App, which allows you to stream audio and video from the server. Video streaming is done with Flash. You should disable transcoding for MP4 files, since Android's Flash Player can play MP4 native.

VLC Remote

Use VLC Remote. Instructions are on he homepage. While this is mainly a remote control app for VLC it's also able to start a stream which you can receive either also with VLC Remote or with any other streaming capable player. I suggest RockPlayer.
To start the streaming, open VLC Remote, connect to the VLC instance on you streaming server, browser the files and press long on the file that you want to stream. A context menu should appear, from where you can choose stream.

Root Option

One option, that needs root, is to use cifs manager to mount the windows share with you video data, which enables other players to play the video as it was stored locally on your device.

Paid Option

This would be Plex.


How can I make my HTC One stop vibrating on notifications, but still make noise? My HTC One vibrates every darn time the notification sound comes on, and I cannot for the life of me figure out how to get it to stop. I have "vibrate on calls" unticked in the setting, under sound, and it still does it. This was never a problem before that system update a little while ago.

I am seriously so mad right now.

Help?

Yes, I too went in to Settings > Accessibility and turn off for reminder of notifications. That fixed it for me. (For HTC 826)


How can I change the data usage cycle day for Wi-Fi? Changing the starting day for Mobile data was already non-obvious as shown in this answer.

Now, how can I change the day of month for Wi-Fi usage as well? Currently, I have the following cycles cycles:

Jun 6 - Jul 4
May 9 - Jun 6
Apr 11 - May 9
Mar 14 - Apr 11

I would like to change these to:

Jul 1 - Jul 4
Jun 1 - Jun 30
Etc.

How can I do that? I am running Android 4.2.2, Cyanogenmod 10.1 from git. This is a longstanding issue that I experienced with ICS too.

I wouldn't use a stock app to do this. I have tried using the stock app to do data managing and it's really not that great. My Data Manager - Data Usage is a great app that will do fine for your situation. It is free of course, so nothing to lose.

Here is their YouTube video if you want to just check it out.


How do I open a used notification in Android? Does it have someway to "re-use" the push notifications? I know that exists a way to create a shortcut to only view the used and past notifications. I want something that gives me the oportunity to use again some notification that was gone.

Example:

I have some Instagram Notification:

Fulano liked your photo.(When I touch in this notification, Instagram opens directly in that pho)

So that notification disapear.

I want to see again this notification and I can touch again and see the photo from instagram.

Someone know some application about it?

You can't put a notification back in your notification list natively, but there is a native settings shortcut to let you see your notification history. New shortcut > Settings shortcut > Notifications


Home screen icon for terminal program? I'm using terminal-ide http://code.google.com/p/terminal-ide/ which is basically a terminal for android with all sorts of utilities. One is able to create bash scripts for example. Is there a way to create an icon on the home screen that will launch one of these scripts?

Is there a way to create an icon on the home screen that will launch one of these scripts?

There is another way (other than this one) if you happen to use Terminal Emulator for Android app. It allows a widget which can be used to execute a script.

Install that app, choose Term Shortcut widget in your current launcher.
Corresponding to Arguments enter:

sh <FILEPATH>

In my case, the query was:

sh  /sdcard/airdroid/dd.sh

As for the root access, you can either provide su access from inside the script and use the aforesaid command for execution, or do:

su -c "sh  /sdcard/airdroid/dd.sh"

Choice is yours!

Choose icon or shortcut label as per your needs, tap OK and an icon would be placed on the home screen.
Tap the icon, the Terminal Emulator app window would open and the script would execute, just like in Desktop GNU/Linux.

We're good to go!


Is Android FAT / FAT32 implementation power failure resilient? Does the android FAT/32 implementation handle sudden battery removal?

I know that Symbian's 'Rugged FAT' (efat32.fsy) and Microsoft's T-Fat implement this, but I've not been able to find any information regarding Android.

Fat32 in Android usually only applies to the External SD card, no longer supported by Google. AFAIK it was a fairly generic implementation as it was only for the card.

Since most of the newer devices use eMMC,the file system android uses is ext4 except for firmware, which is vFat. Example below is from a Galaxy S4

It depends on what filesystem, for example /system and /data are yaffs2 while /sdcard is vfat. This is the output of mount:

How can I sort, filter and tag files/images in Android ICS 4.0? A little background

Im a bit into graphic design, digital painting etc, and I like to draw on the run, away from my desktop. For drawing, I often need reference materials - some pictures of things I would like to draw. While drawing/designing a futuristic car, Id like to be able to look at pictures of some modern cars, planes, helicopters, materials etc.

Looking for reference on the Internet on my android tablet is cumbersome, and I dont have Internet access everywhere. I do have a big library of reference pictures on my SD card tho.

I cant really use it as reference yet, because looking manually for pictures of things I want to draw is a LOT of work. Designign something, say a cyborg, Id have to dig through the files searching for "human", "metal", "machine" and "mechanism" pictures.

So, what do I want?

I would like to tag and sort for pictures/files with tags similar to those I mentioned ("human", "machine", "engine" etc), but i dont want to upload it anywhere or use it online. I dont want to share and want to keep it local, usable without Internet access.

If I could display all the chosen pictures on one screen, it would be a big bonus.

How could I do that on my Android tablet? I'm using ICS 4.0.

As long as pictures/videos are involved, you might want to take a look at Monte Gallery. This app offers you a.o. the feature to add descriptions and tags to pictures, and then lets you browse them by tags. It also offers browsing by location, and (as you can see by the screenshots on its market page), a nice "calendar view", grouping pictures by "date taken". Only thing missing is to combine those using a search mask, like "show me all pictures tagged foobar taken between [dates] on [location]" :)


Samsung Galaxy S3 Aux Cord I drive a 2007 Saab 93 without any bluetooth capabilities. I tried to play music with an aux cord and the car senses that my phone is connected but when I try to play any music my phone plays it through the built in speaker and not through the car stereo. I'm just wondering if there is a setting or anything that I need to do in order to play music?

Thanks.

I have found that the auxiliary jack on my S3 is pretty tight and even when the phone senses I've plugged something into it, I have to press it just a little harder, until I hear a "click" and the plug is flush to the phone (you should not be able to see any metal from the plug showing).  Once I do that, the sound stops playing through the phone's speaker.


How can I use another phone's camera in place of my camera? Ok, the problem is my camera's protective glass cover has wore down and now some dust has entered, causing the camera's output to become blurred. This is causing me a lot of issues currently, especially when I need to scan some QR code. For example, now I can't login to WhatsApp on my PC, cuz I need to scan their QR code with my phone.
What I want is, use another phone's camera instead of my phone's camera, just like the DroidCam functionality, where you use your phone's camera instead of your PC's camera. Are there any apps designed for this purpose?

Here's my suggestions:

Firstly: If your phone has a front-facing camera, use that.
Secondly: grab a can of air duster and spray the rear-facing camera out( if this clears it up, then find a crystal clear tape and cover it. Or get a case that covers it.)
Lastly: I'm taking the assumption that you do have another phone. If so, just take the photo and transfer(via bluetooth, text, cloud, etc.) it.

Hope something helps.

Find application size on Google Play Store Google Play site on PC doesn't show application size. Additionally, after last update, Play Store application doesn't show application size either.

Is there a way to find application size without downloading/installing it?

In the app and in the website, you can only get the size of the APK.

But for additional downloads (extensions), it's usually not documented, but they can go to as much as 4GB. See this SO question: https://stackoverflow.com/questions/21330911/max-size-of-an-android-application

In some cases, it just says "Varies with device".


How do you turn off developer mode on an s5? I turned developer options 'off', but is there anything else that needs to be done? Not my phone so don't want to mess anything up :-)

You can actually hide the Developer options permanently from the menu until someone enables it again. Just follow this -

Menu > Settings > Apps > All apps > (find) Settings > Clear data > Confirm

Developers options will be turned off automatically although they are enabled by following the above step.


Can prolonged use of the GPS cause adverse affects? What happens when the GPS runs continuously (more than 5 hours) in an Android device? Can it cause the battery or GPS receiver to overheat? Will it be able to keep determining my location correctly the entire time?

Mainly there should not be any hardware problems if the unit was tested correctly.

For other information you can use this application that has also power monitoring for GPS.


Prevent Notifcations stopping Music Playback On a Note 2, if I am listening to music or a video, whenever a notification comes in, the audio from the music or video is stopped to play the notification sound.  This happens in any app I have tried, though I don't use the stock samsung apps much.  MX Player for video, Pandora for music, as examples.

If watching a video, this means skipping back to rewatch the portion that had no audio.

Is it possible to have sounds from different sources mixed, rather than have the notifications take over the whole channel?

You can turn off notifications or if you have access to an app like SmartActions, you can create a rule that does that.  But if you are using WiFi or mobile data, your best bet is to turn off notifications....annoying yes, but it is but necessary


How to root an Android emulator My application required to use some system command such as wm size and wm size reset to change the screen size so an application supposed be running on Portrait only mode will be displayed as portrait in a landscape screen.

I have gone through many of the answer in stack overflow but still can't get an idea of how to do it.

Somebody can give me a step by step guide how to achieve this thanks. I've tried the Andydroid emulator but still not work.

I know the emulator is rooted when using adb console but looks like if I test it with my program, it was not.

I have found the way to root. Only work on certain API Level stated in their answer.

My Galaxy mini having trouble with charging Today I noticed that my Galaxy Mini is not charging properly.

In morning it was switched off even after charging for the whole night. Some weeks ago the same problem had occured, but some time after when I plugged it in with the USB cable it was getting charged. When I connected the charger, it was working fine.

Well, my problems don't stop there. Today I did all the possible tricks, but it doesn't charge. In fact it is showing the charging symbol, but its not increasing. It's not even showing the charging percentage. When I connect it with the PC via USB cable it is charging and battery level increasing too, but it again suddenly decreases or again increases.

What is the problem? And how can it be solved?

The battery may be ok.

I had this problem and fixed it.

1) Plug the phone into a charger.

2) The pins get loose, so press the battery towards the pins and press the on button.

3) Once the phone starts to boot up, you can take the pressure off and replace the back onto the phone.

Whoolahhh!


Is it possible to Unlock bootloader at phone with MIUI without registration? Is it possible to Unlock bootloader at phone with MIUI without registration at:

No, it is not possible. You must register.


Contact names not showing for the calls and messages My Galaxy S3 was working great until I installed a firmware update on 26/11/12. Immediately after, the names dropped off the calls and messages and it is now showing phone numbers only. When I dial somebody or receive an incoming call, only the numbers are displayed not the contact name.

Please help....

Had the same problem with GF's phone. The problem was caused by an update. There are talks of a possible fix on Vodafone.com.au forum via upgrade but the simplest solution, instead of waiting for fix (which may never come to all carriers), is to do a factory reset.

Make sure to make a backup of your phone before doing it because everything will be gone.
Step-by-step for factory reset is available here.


Installation in system/app without root I know I can install my application in the /system/app folder with root access. But is there any way to do it without root access?

No.

Users are not allowed to write to the /system folder/partition. Any sort of exploit or method that would allow this partition to be writable is equivalent to root access on the device.

Some other examples besides root are: "Rooted recovery" which is a recovery partition that has more features than the standard Android recovery; an "Engineering" (HTC) or Unlocked (everyone else) bootloader; or a file-permissions exploit, which at that point you might as well put su and SuperUser.apk on the phone anyway...


Chromium: Option to save passwords and change encryption greyed out I am using Chromium build 353428 on PacROM 5.1. After signing in with my Google account,  I tried to set a separate sync passphrase (using instructions given here). However, when I click on my account name second time (with caption "Please update your sign in details"), the next screen has entries for "Password" as well as "Encryption" greyed out. Curiously, in Settings → Save Passwords, the options to save passwords is active.

Do Chromium builds support saving passwords and encrypting them with separate passphrase? If yes, what might be causing the above mentioned behavior?

A reboot might fix the issue (it did in my case). No idea what caused it though.


How can I list all files in a directory with timestamps (in a touch compatible format) on Android For starters, I am on a Nexus 5, on Android 6.0.1 and I am rooted.

Normally, I'd just do this

find /path -maxdepth 1 -type f -printf '%TY%Tm%Td%TH%TM%Ts %p\n'

However, it appears that busybox, though it gives a lot of functionality, does not include the printf feature of find.

Is there any way I can do this, or possibly even get a fully functional version of Find?

I found a version of findutils compiled for Android here

http://forum.xda-developers.com/showthread.php?t=1268589

I did the following.

I copied the find binary to my phone
I moved it to /data/local/tmp/find
chmod +x /data/local/tmp/find
Ran the find command I wished to run

(I am rooted, but I did not use the su command here, so I'm not certain if this requires root or not.  I have an unrooted phone I can test this on later to see if it's still possible in those circumstances.)

I made a shell script to assist with my ultimate goal.

cp /sdcard/find.bin /data/local/tmp/find.bin > /dev/null 2>&1
chmod +x /data/local/tmp/find.bin > /dev/null 2>&1
/data/local/tmp/find.bin "$1" -type f -printf 'touch -t %TY%Tm%Td%TH%TM '"'"'%p'"'"'\n'
rm /data/local/tmp/find.bin > /dev/null 2>&1

EDIT: This appears to work on an unrooted phone as well!!!!

EDIT2: While this step works, you need to be rooted to change the modification time with touch, so this isn't useful for what would come next.


What is the difference between CMDA, GSM, P1000L. and P1000N? I'm looking to root (cyanogenmod) a Galaxy Tab I have lying around. Looking on the CMG site, I see that there are 4 different versions: GSM, CDMA, P1000L, and P1000N.

What are the differences between these? And how can I tell what version my tablet has?

GSM and CDMA refer to the 2G/3G cellular technologies used by phones and tablets.  In USA, AT&T and T-Mobile use GSM, while Sprint and Verizon use CDMA.

GT-P1000L and GT-P1000N are variants of the international Galaxy Tab GT-P1000 version that were released by Samsung for Latin America markets.  Both P1000L and P1000N models have GSM connectivity.  You can find the exact version you have in Settings -> About under the Model number section.

In terms of rooting and installing CyanogenMod, you will need to refer to the CyanogenMod wiki for the respective model (P1000L or P1000N).


It the any map app which is using google maps APIs but work perfectly without GPS? As I have searched - everybody asking about OFFLINE maps, but I am asking about maps which can use just simple google maps, but does not ask any permissions to GPS.

Currently original goolge maps are without GPS location permission, but they are not working until I turn ON the GPS. Maybe there is any option to force google maps working without asking any location data.

Usually, I know my exact location (when I am walking) or I can determine it very fast - just go to the road cross and you know your position +/- 50 meters. Then I just want to find the shortest way to location I choose.
I don't need any offline map - it won't save battery. But turning the GPS off - does.

Edited:
Turn on the battery saving is not an option - the vibration will be turned off. I don't use sound for calls (I even don't know what is the current ringtone). But you gave the nice idea - just turn ON the GPS, launch maps (without any permission) and after that turn off GPS.

If your goal is to save battery life by disabling GPS, then simply disable GPS. In Settings, set location mode to "Battery saving" (WiFi + Bluetooth, but no GPS). This leaves location services on, but disables GPS. Android will still locate your device using WiFi techniques, but not using orbiting satellites, which takes more power.

Further, I can use Google Maps without location services enabled, at least on Android 8.1. Google Maps asks you to enable location services, but you can just say no.


HTC one M8 won't flash RUU or unlock Bootloader I hope u r havin a good day

-I just found out that model on the back of the phone is 0P6B100 while it's 0P6B700 in getvar, I found that out after trying all the x.xx.651.x RUUs flashed down below cuz i thought it needed sprint RUU

first of all everytime i reboot i find the same apps installed , pics and missed calls no matter how many times i erase all that and if i installed new apps every reboot it's not there, I wanted to get it back to stock as new but i couldn't and here what i have tried :-

1-couldn't flash stock or custom recovery [failed (Remote : Not allowed)] cuz bootloader is locked, And i couldn't unlock bootloader .

-(after getting unlock code from HTCdev.com and installing it and after selecting yes on the phone to unlock bootloader, phone just reboots)

2-tried to flash RUU (3.30.651.2 & 4.25.651.14) Wizard while phone was on fastboot mode

https://onedrive.live.com/?cid=AC7BF...d=root&o=OneUp

-Phone couldn't boot into bootloader while on fastboot mode so it reboots regularly.

3-tried to flash RUU (3.30.651.2 & 4.25.651.14) wizard while phone was on

https://onedrive.live.com/?cid=AC7BF...%21341&o=OneUp

-did the first steps ok but again when wizard is waiting for bootloader while phone was in fastboot mode, it just reboot regularly.

4-tried renaming another (4.25.651.14) RUU to 0P6BIMG.zip and put it on sd-card and went to Hboot.

https://onedrive.live.com/?cid=AC7BF...%21341&o=OneUp

-after clicking yes to confirm the update, Phone rebooted in the middle of the steps .

5-tried flashing same 0P6BIMG.zip from recovery mode.

https://onedrive.live.com/?cid=AC7BF...%21341&o=OneUp

-after 3 mins of hope crushed by verifying update package.... - Installation aborted....

-I want to erase everything and start over with any rom or any recovery.

-Thanks in advance...

You will need to unlock the bootloader of your m8 before being able to flash any RUU or custom ROM on it.

In order to do that, I suggest you to visit the XDA forum for the m8 - bootloader threads (XDA is clearly the best site for anything phone related), and try to find one of the many ways to do it that suits your phone and its current state (you might have to change the bootmode - it is now on fastboot).

Best of luck.


The back, home and menu buttons are not lit but they work. How can I make them backlit again?
I have an ALCATEL ONETOUCH IDOL 2plus
Thanks and regards

Please check through these steps.

Just reboot and see whether it functions or not.
Goto recovery mode and clear cache data and check.
Do a factory reset and check.

After all these if no response, it may be a hardware issue, take the device to manufacturer's service center and check.


What are the consequences of flashing a modified rom with Knox enabled bootloader on a Knox enabled samsung phone? For instance I want to flash OmegaROM v21 on my Samsung Galaxy S4 GT-i9505. OmegaROM v21 is a modified Samsung edition of Android 4.4.2 Kit Kat.

According to the information in the xda-developers forum, the ROM contains a new Knox enabled bootloader. As what I understand by reading the related related research thread in the xda-developers forum and the information provided by Samsung, this will have the following consequences:

The bootloader will detect the unsigned Android kernel and because of that,
The Knox warranty flag will be set to 1.
On the boot screen it will be visible that the Knox warranty is void.
It is not possible to reset the Knox warranty flag
It is unlikely, that there will be a hack for resetting the Knox warranty flag because it is stored at a very low level, maybe in an eFuse or in the TrustZone of the ARM processor.
I will not be able to flash an older ROM. (Why? Because it will need an old bootloader and the new one disallows that?)
I will not be able to use Knox enabled apps.
I will not be able to use Knox enabled infrastructure.
I will not be able to use Knox enabled DRM.
I will be able to flash new and modified / unsigned custom ROMs
I will be able to use normal apps, infrastructure and DRM.

Are my assumptions correct, and will I be able to use DRM based services like Spotify, Amazon Lovefilm, Google Play Music, etc?

From everything I've read about the "Knox enhanced boot loader" , and what is and isn't possible with it, all of your assumptions seem spot on. Another route you may want to try,  is Safestrap. It's by far the safest method for installing custom Roms, as it bypasses the bootloader and there's no chance in tripping the Knox flag, unless you flash a Rom on the stock side. If you haven't heard of Safestrap,  Just a quick Google search will point you to it.


Screen goes back to home screen frequently, after Data Network enable When I enable Data Network, my phone goes back to home screen frequently whenever I use another application or go to another place. Even when I close my screen, my home screen appears. How to fix this error? When i deactivate the data network mode, the phone works normally.. please please please update me the solution on it.

My phone is Samsung Galaxy S plus.
Model Number - GT-I9001
Firmware version - 2.3.6

Same phone. Never had this happen to me.
Using a custom ROM though. BroodROM Business Edition.
I would recommend upgrading your system or flashing a custom ROM.


Error "mount: operation not permitted" when trying to mount system as read/write I am trying to mount system as r\w and every app couldn't do it including root explorer and link2sd. I am using Xperia z2 android v4.4.4 and I the device is rooted and I have restarted the phone.

I get the following eeors when trying to do this:

mount -o mount,rw rootfs /
 mount: operation not permitted

This is how you remount root as read-write:

 mount -o remount,rw /

If you want to remount the system partition as read-write:

mount -o remount,rw /system


Photos sync - where did the files recover to? I decided to try out Google's "Photos" sync, which can be enabled under account settings. After the sync finished, I did a factory reset on the device and let it restore the photos. It apparently did - they are viewable through the Google "Photos" app.

However, I can't find the files anywhere. Originally they were split into two files: DCIM/Camera and DCIM/Test. Now, DCIM is empty and, when viewing the entire set of thumbnails, it tells me there are no "Collections".

I most certainly expected it to restore the photos in the same structure as they were originally. Not only are the two subdirectories gone, I can't even find the png files. What am I not understanding?

I did this on a Moto G, running Android 6.0

From the photos app, you can't recover onto your device. You can only view them , the restore option is a misnomer as it does not really restore to your device:

From Google help, where a similar question is answered. This thread is recent and makes it clear that there is no way one can directly restore photos using the app. Options are:

Use the Google Drive app to select and download the photos. Using a file manager, copy the photos in downloads to the directory you wish to (see Nicholas post of 11 Jun)
From the Photos app, select and download ( of course, you will need to move them using a file manager - Krissy post of Jan 01)
Use a PC to download from drive and move into desired folders or use third party apps that can facilitate downloading from the photos app


What can an app like WhatsApp acess on my phone The app WhatsApp would like to have permission to access my device's photos, media and files.

If I grant permission, exactly what can (could) the application access?
Can it access all of the photos on my phone?  Or just the photos I have shared or downloaded with the app?
Can it access all of the phone's media?
Can it access all of the files on the phone?

Or does Android restrict what it can access?  If so, what does it restrict it to and how?

I'm not interested in what WhatsApp says it will or won't access, or even what it has promised in its EULA.  I'm interested in what it could access, if it wanted to.

You can take the description "device's photos, media and files" for sure. If you grant this permission to Whatsapp everything that is located in your "internal storage" (sometimes called sdcard section).
This includes:

Photos (usually stored in the DCIM folder)
Videos
Downloads
Music
Ringtones
...

Only on phones running Android 10 or higher because of the new "scoped storage" feature the access is a little bit limited. And starting with Android 11 it seems like Google will narrow down the permission you grant on the common files again.


Why my viber changes my status without me using it? My boyfriend sees my Viber status changing from online to offline, while I don't even open it. He thinks I talk to someone but I don't use it. I have a Galaxy Note 7, he is using iPhone 6.

Viber is running in the background, so it can be still online if it wants. Because it's tracking your activity on your phone, it knows when your phone sleeps (the phone makes no activity in the foreground, in other words, your screen is black (off).

But, when you are using your phone to check your emails or to call someone, Viber knows that your phone is not sleeping and makes actions in the foreground, so Viber shows you online, because it's thinking you are ready to chat, and it's same when you get notification from another application (your phone wakes up and makes notification on foreground, you can see it, when your screen turns on).


How to update samsung galaxy tab p1000 i.e. 2.2 to 2.3. using ADB? I am updating the OS of my Samsung Galaxy tab p1000 (i.e. 2.2) to 2.3.6 using adb.

I am using the steps below:

Check whether device is connected or not using ADB.

C:\Users\PC>adb devices
List of devices attached S6802084d305f device

Push 2.3.6 OS (i.e. update.zip) OS to SD card.

C:\Users\PC>adb push C:\Android\update.zip /sdcard/update.zip
2765 KB/s (2260360 bytes in 0.798s)

Go to recovery mode

C:\Users\PC>adb reboot recovery

After selecting Apply sdcard: update.zip, I'm getting the screen below. But it shows it for long time. There is no response from device. We waited for 5 hours. No response.

How can I flash my Samsung Galaxy tab? Let me know if I am missing a step.

These are the steps to install/update a custom ROM from stock:

Install a custom recovery (Clockworkmod for example).
Copy the ROM zip to the phone sdcard (you can do this via adb).
Reboot in recovery (it will load the custom recovery).
Use the option to install zip from sdcard to install/update the ROM.


What is this notification symbol for? I’ve circled the icon in red. What is this notification/alert for?

This icon has to do with parent supervision. This means that someone is supervising your mobile phone and that your mobile is in a kind of "children's mode". Can you click on it?


How can I syncronize android time with machine via ADB How can I update android time via ADB?

I know I can run this comand via windows cmd:

adb shell date -s 20140414.130000

But I need to synchronize the time with my windows machine.

Is this possible to accomplish?

I found a solution for this by using the perl.

I created this perl script, which sends the current date with the correct format to the android device via adb:

use Time::localtime;
$_=localtime;
system'adb','shell','date -s',sprintf("%04d%02d%02d.%02d%02d%02d",$_->year+1900,$_->mon+1,$_->mday,$_->hour,$_->min,$_->sec)

Then I just need to open cmd and run this:

perl < clock.pl


What are the differences between the two Samsung Galaxy Tab 4 7.0" models? I have just got a new Samsung GALAXY Tab 4 7.0" (SM-T230NU).

What is the difference (or improvements) between the 'stock' SM-T230 model GALAXY Tab 4 7.0" and the 'newer' SM-T230NU, recently released for US/Canada and in EU?

Are there also other NU devices? I have also seen references to the GALAXY Tab 4 10.1" as SM-T530NU.

I have found one possible issue, with the SM-T230 not having multi-user mode:

  The multi users setting is not available. According to the manual it should be at settings => General => Users.

(My device does have multi-user capability)

I also saw a reference to the two different models on XDA Developers:

  Do make sure your tablet is a T230NU model and not just a T230
  model.

UPDATE: 04-Jul-2014

There are three variants: T230, T230NT, T230NU

from: Samsung T230 | T230NT | T230NU Galaxy Tab 4 7.0 WiFi Firmwares

According to other reviews, the plain SM-T230 does not support OTG,
but the SM-T237p does.

I remember how disappointed I was to find this with my SM-T210R.


Connect from Android to SSH server without password I want to run scripts on an Ubuntu PC from my Android phone just with a tap, no passwords or other stuff.

Things I did so far: I managed to connect via SSH to the PC, but I cannot configure a public-key authentication (I'm using CM9, for what it matters). I could create a rsa key on my phone (and stored it on the server) but it's like it's not using it when connecting, so I tried using the "ssh -i" flag but then I get an error that the string is too long. ConnectBot rsa authentication works well, but I cannot use it to run scripts. I also tried installing dropbear but I stopped as soon as I needed to compile stuff, because I could not find a complete guide, or they are mostly describing the opposite process (install an ssh server on Android). To run the scripts I use "Script Manager - SManager" that allows the creation of widgets, but so far it's always asking for the password.

Can you suggest a proper way to use pub key or any alternative solution?

Thanks!

P.S.
I know this has already been partly discussed here: Where to add SSH keys to allow connections to remote server on Android?
But it does not work and I cannot comment that question.

When you provide the key (using -i switch), you should provide the path to the file, not the key itself - are you entering the file path?


How to turn on USB mass storage with JellyBean I have a Samsung Galaxy Tab 2 7.0.

I have files on an external SD card but I cannot mount the tab as a usb drive from my computer  - I cannot find a way to turn on USB Mass Storage.

How do I do this in JellyBean?

Starting in 4.0 (actually 3.0, but few devices used that), most Android devices use the MTP (Media Transfer Protocol) class rather than the Mass Storage class.  This was done for various reasons, including the annoyances attendant to having to unmount the SD card from the Android device to access it from the PC.

Samsung has embraced this new way rather fervently and doesn't allow mass storage at all under normal circumstances (If you have root, you can force it on some devices.  Not sure if it works for a Tab 2).

MTP mostly "just works" on Windows since XP and on Mac, though getting it working on Linux can require a bit of effort if you don't use GNOME.  The Arch Linux wiki has a useful article on the ways and means of accessing MTP devices on Linux.


How can I get Helium to work on my One? I'm trying to backup apps on my OnePlus One using Helium.

When I open the Helium Windows Desktop application, it works some magic and tells me Helium is now activated on my phone, but the app still shows a spinner and says it's waiting to be activated.

As noted in the thread [How to] Helium Backup by Bassick, one should use the Helium Chrome app to activate Helium. Then it will works just fine.


How to root LG Optimus L3 E400 Smartphone How to root LG Optimus L3 E400 Smartphone?
I followed the instructions on this webpage:
http://www.rootlord.com/2013/02/root-lg-optimus-l3-e400-smartphone.html.
But nothing happens, it says on the site that after the process is complete there should be an app in the app drawer called "Superuser" with a green icon, but its not there.

This is the model that Google Play displays: Vip MK LGE LG-E400

This is the output i get from the application:

Thank You

I tried using the same program and many others to root that phone none of them worked, except for Key root Master MOD (This app is in Chinese but it still works as I have used it my self and succesfully rooted my Lg e400f).

Instructions:

Download the Key root Master MOD. I uploaded it to my Google Website here. Scroll down to the bottom of the page and download the "Install.apk
Sideload the APK
Click the second button Mulai Root and a popup will show
Click the button that says root and another popup will show button in purple with 2 buttons (one red and one purple)
Click the purple button
Your phone should be rooted and have SuperSU installed
Optional: Use a root checker to check if you actually have root privileges

This was the only root method that worked for me, as all the other ones didn't work.

You may see Stop Looking And Root Phone Here! youtube video. I didn't use this video for my guide but this shows you how to use the app (as the app shows interface in Chinese language).


Can i recover data from a Nandroid Backup without the original device? I'd like to start making scheduled backups to my rooted OnePlus 3T (Oxygen OS 5.0.1) in order to prevent the loss of data from any reason that could occur.

I want to save everything: the entire content of /sdcard and the apps+data. I know doing a Nandroid Backup with TWRP is the best way to make a complete backup of an Android device quickly, but i have a question:

Is it possible to recover data without the original device? If i had a totally new device, would it be possible to extract some specific data from the backup? (For example, read and extract the /sdcard/download directory from the backup, or also extract the data from a given app)

That would indeed be possible. There are several apps which are able to extract parts of a Nandroid backup, e.g. Titanium Backup or ROM Toolbox.

Apart from that, depending on the format used by your Nandroid backup, you can either mount them as loop device (disk images) or unpack them (tarballs) to invesigate/access all contents.

For further details, I'd recommend a look at our nandroid tag-wiki – and especially follow up to:

Restore only part of nandroid image

Nexus 10 completely dead after lollipop update So, tried to install the new update when it flashed on my tablet.  Left it downloading, and then clicked to install.  Its now a brick. It cant boot, it has no commands.  I have tried factory reset, and nothing, it still has no command.  I dont know how to flash it, although im not dumb I could likely follow good step by step instructions, I just dont know where to start, or who to turn to.  I suspect the size of the update is what went wrong, I only have satellite internet at 512kbps.  The update was 382 meg.  My device wanted to isntall after about 20 minutes, and I can confidently say that any download of 400 meg would take about 5 hours on my connection, so idk if it tried to install something and just gave up?

Whatever.. i have a dead android on his back with an exclamation mark.  I tried Reboot, recovery, factory reset none of which worked.

Many thanks in advance for time or trouble taking to reply.

Alison

If you are still able to boot your nexus in fastboot mode(hold down the power button and the volume down button) you can recover it quite straightforward:

Download the desired nexus firmware from here: https://developers.google.com/android/nexus/images#mantaray
Search for a howto flash your nexus 10 via fastboot. Something like this if using windows: http://nexus10root.com/nexus-10-unroot/how-to-unrootunbrick-nexus-10-factory-firmware/

Flashing through fastboot requires an unlocked bootloader - unlocking will remove all your userdata!

If any questions appear just ask ;)


Wrong language in a new Chrome private window and in integrated data I have a problem with my Motorola G1 smartphone. Recently, I did a factory reset and since then I have a problem with the language. My phone is set in English and I live in the Netherlands, but when I search something using the search bar in Chrome in a private window, Google is set to French. This is weird, since I do not have anything in French: not the language of my smartphone, nor the keyboard, nor my IP. And when I search, Google is set to google.nl, so the IP localization is right, but there is something wrong with the language, that is set to French. You can see this in the first picture.
I noticed that I have the same problem when I have "integrated data" (I don't know if there is a better expression for this), for instance when a website reports an Instagram or Twitter post. An example is in the second picture. There you can see an Italian website, with my phone set in English and with a Dutch IP, however, you can see that the Instagram post reported in the website is in French.

I have really no idea how to fix this. I checked in Google settings, I changed the search language in Chrome to English, but every time I open a private window I see the results in French. Any clue on how to fix this?

I actually solved my problem myself. On the Chrome app, I clicked on Settings-> Languages (in the Advanced category) and then I removed French from the language list, which apparently set to be my first language, I don't know for what reason. Now pages do not display anymore in French, so the problem is solved.

I would like to keep the answer on the website, it might be useful to someone, but admins can delete it if they think it is not useful.


can fastboot be used to backup device? Many people tell about fastboot that it can be used to flash a image on one of the partitions.

Is the reverse also possible, that is take a binary snapshot and store it as a zip file containig the exact binary representation of the partition to be backuped?

the reason I ask this is
backup has two steps.

1) take and image/snapshot to backuplocation (backup)
2) and replacing image/snapshop from backuplocaito (restore)

to me it seems that fastboot is only doing one, while being able to write to the Androids internal flash (in binary "dd"-style) seems it should also be able to read from the flash.

This way nobody would need to organize and run another potentially not trustworthy rom to do the reading job.

If you check with our fastboot tag-wiki, and follow up the link to the List of fastboot commands, you will see the answer is NO. Fastboot only has commands to write to the device. A few exceptions include:

making sure there is a device at all, using fastboot devices
some OEM specific commands to read configuration values (fastboot oem <option> – note that all those, except for oem lock/oem unlock, options start with INFO?)
several bootloader specific commands
rebooting the device after "work done" (fastboot reboot / fastboot reboot-bootloader)

From the CyanogenMod Fastboot Intro, emphasis mine:

fastboot is a small tool that comes with the Android SDK (software developer kit) that can be used to re-flash partitions on your device. It is an alternative to the recovery mode for doing installations and updates.

Wikipedia describes fastboot as a diagnostic protocol included with the SDK package used primarily to modify the flash filesystem via a USB connection from host computer. (again, emphasis mine).
No source speaks about backing up partitions (or data) from the device.


Linux command 'w' - how is this as command written in Android shell? I am searching for similiar commands in Android shell - as they are used in Linux like these commands - what can I type in Android terminal for :

  w

  who

  whoami

?

Thank you.

Linux commands w and who read login information from file /var/run/utmp. Traditional Linux sysV login records/logs like utmp, wtmp, btmp and lastlog are set and read by some programs that make use of GNU libc (the most commonly used C library on Linux distros) and other libc's. These files contain information about currently and previously logged-in users.

However there is no concept of Linux console login on Android as it isn't designed for multiple user logins. Virtual terminals are disabled on Android by default, init doesn't start getty, and hence there is no login, no login manager (like logind), no shell at startup and no user sessions, and therefore no login files. Android boots directly to GUI. Other CLI programs like sshd that read/write these login files are also not part of Android. So Android's Bionic libc neither provides the functions of utmp.h, nor filesystem hierarchy contains /var/log or /var/run. However if a program linked against standard Linux libc's is used on Android, it will try to access these login files. But if a program - like w, who, users, last and lastlog - is totally dependent on these files, it simply won't work. You can use busybox such as yashdsaraf's to get all these commands on Android.

Linux command whoami gets the (effective) UID of process by making syscall geteuid directly to kernel and then on Linux , if possible, resolves ID to name using name resolution mechanisms like directly from /etc/passwd, /etc/group or through NSS, NSCD etc. id command additionally does getgid and getgroups as well. So these commands work on Android as expected and - along with other similar tools logname and groups - are part of toybox; Android's choice for all-in-one Linux command line tool.
Bionic libc's wrapper functions (that apps actaully use through Android APIs to get UID) and kernel syscalls are also identical as is the case with other libc's:

~# nm -C /system/lib64/libc.so | grep geteuid$
0000000000070d58 T geteuid
~# grep geteuid$ /proc/kallsyms
0000000000000000 T sys_geteuid

Android Chrome browser is making a duplicate of every photo downloaded to my external SD card Every time I download a photo (.jpg or .png file) with the Chrome browser (stable version) to my external SD card, it gets duplicated and stored also in "/storage/emulated/0/Pictures" folder (internal storage). The duplicate has always somewhat a smaller file size. How can I disable this and why is this happening ?
This doesn't happen when I download a photo with Opera Mini or MS Edge browser to my SD card for example. It only happens to pictures downloaded with Google Chrome when the download location is set to "SD card".
My SD card is formated as portable storage on my HTC 10 (Android Oreo).

This answer I found on google.support and I  Copied and pasted, I'm not sure if that's okay? Or not I'm sure I will find out momentarily .
We are aware of this issue and are working on a fix for this. To resolve this immediately, you'll need to reset the permission for the Google Photos App by following the steps below. Once these steps are complete, the duplicates should disappear after a few minutes.

Long press the Photos App icon
Tap the "i" button on the top right corner to go into App info
Tap "Permissions"
Tap "Storage" under Allowed
Tap "Deny" and tap "Deny anyway"
Re-open the Photos app
Tap "Allow" when prompted with "Allow Photos to access photos, media, and files on your device?"
Hope that helps....    :)


Nexus 4 does not turn it on and blinking red notification light only This morning, my Nexus 4 (Android 5.0.1) had some issues about Google apps crashing. I decided to do factory reset, so I went to Settings and apply factory reset, it was showing power turn-off, then it has not been started again. I tried to plug charger and everything but nothing is worked out.

Now, when I plug it to wall USB charger or laptop USB charger, I can't see any charging icon. I tried to hold down power + volume down buttons, but nothing happen. However, when I hold power + volume down buttons and plug it to any charger, it shows red notification light which blinks for 10 seconds. Releasing the buttons made the light go off.

Tried below solutions, but nothing worked for me till now:

Put it charging more than 2 hours.
Checked solutions from Red notification light on Nexus 4, won't power on, device unresponsive too, but no success.
Checked this Deep Hibernate solution from here
Also tried XDA developers solution

Any other possible solutions?

I have the same problem once a week and have a little different solution (workaround):

Unplug the phone from the charger
Press and hold the volume down button plus power button for 15 seconds
Plug it into the wall-charger (while still holding both buttons!)
-> the red light should start to blink.
After 4-5 blinks release the buttons
Wait some seconds and then press the power button and it should boot

Maybe this workaround will help you.


Can't connect an already booted device to adb Every time I want to connect my phone to adb via USB I need to turn it off, plug the cable and turn it back on.

Is this the right way to go or am I missing something?

Documentation doesn't seem to explicitly state that.

Some details:

Samsung GT-B5510 Galaxy Y Pro (Android 2.3.6)
Android Debug Bridge version 1.0.29
Debian GNU/Linux 7.0 (wheezy)

I have had similar trouble with a different device.  After you plug you device in try:

adb devices

If your phone is not listed, try restarting ADB:

adb kill-server
adb start-server

Lastly, check if there are any driver updates for your phone.  A good place to start looking for drivers is Google's OEM page and Samsung's support page.  Additional tips might be found on this SO question.


How to uninstall or replace Joy Launcher? This morning my Android mobile started asking for permissions for a "Joy Launcher" app that I've never seen (or at least noticed before).  This appears to be an official app from the manufacturer.

https://play.google.com/store/apps/details?id=com.tct.launcher

I also found this article indicating that Google recently discontinued their Google Now Launcher, but I'm uncertain as to whether this has any bearing on my situation.

http://www.androidpolice.com/2017/02/03/google-will-discontinue-google-now-launcher-coming-weeks/

My biggest concern is that it's suddenly asking for unneeded permissions.  It seems unusual to me.  I haven't been able to disable it.  Can anyone shed some light on what's happening and/or any insight as to how I can remove or replace it?

I ended up disabling Joy Launcher and installing another launcher of my choice.  Joy Launcher can be removed from the startup items using any startup manager.  I very recently switched to the All-In-One Toolbox app, since the Startup Manager app I mentioned above in the comments has gone flaky lately.

VPN disconnects immediately My android phone connect to VPN then immediately disconnects, I tried most of VPNs on Google Play Store but it's not working.

OpenVPN connects barely and disconnects in less than 1 minute, my network is good and I can connect VPN on my laptop with my network.

Is your Android phone killing apps from the background? Check for background activity manage, battery optimizer or a similar option in your device settings and disable it for your VPN app.


Photos Look "Washed Out" when attached I have Galaxy sIII and now when I attach photos, regardless if I do so by txt, Facebook or email, though they look wonderful on my android phone, once sent they look terrible, washed out, bland and so on. I recall dimly that when I first got the phone, I could select the size or something on those lines of those photos, now i cannot. I have tried settings, I have tried everything I could think of (at least for a not very techno astute girl), and still no luck. Where should I look? How can I fix this. Please help.

Make sure that you are taking the photos at full resolution from the camera and also that compression after uploading isn't enabled.

To be absolutely sure upload few photos on Dropbox and view them on PC. Check it's resolution on your PC.


Given an Android phone, how can I find out what custom and stock ROMs are compatible? I've recently started trying to dabble in custom ROMs, or even just trying to boost an old phone with a newer version of Android, but there doesn't seem to be a conclusive place online to find out what ROMs are supported by what phones (and how to root any given phone), what ROMs are available out there in the world in general, it all seems a bit... messy!

So here's my example for my question: I have an Obi S453, how can I find out what ROMs I might be able to install?

This site offers a fairly comprehensive coverage to the questions asked by you:

Where can I find stock or custom ROMs for my Android device?
How do I root my Android device?
How do I update Android on my device?

Coming to your device in particular, it appears there is lack of developer support to create custom ROMs as a quick search (not comprehensive ) did not provide any evidence. Even the OEM, it looks like has not come out with any plans to update to Lollipop, whereas most popular phones have the next version Marshmallow rolled out or in the process of rolling out.

Possible reasons for lack of developer support, in general, could be (i am not a developer, so guessing):

Chipset being not developer friendly
Not a popular phone compared to low cost "budget phones"
Kernel and chip set information not "open source"
Difficulty in porting custom ROM from another ROM
OEM not coming up with a improved versions of phone


How to remove occasional pop-up messages from the provider My Milestone is producing pop-up messages every half an hour with "your credits are low please add more credits". It is really annoying. Is there any way to block them?

Not without either loading a custom ROM that doesn't have these popups. These are probably "features" added for your carrier, so a more "generic" ROM would probably stop them.


How do I hide reviews on Play Store made by my phone contacts? Consider a random app on Play Store. When I visit its page, the reviews shown to me at the top of the list are mostly by my phone contacts (not Google+ contacts).

I do not follow anyone on Google+, although some people might follow me.
I have hundreds of phone numbers in my phone's contacts app which syncs with Google.

I do not wish to see reviews about an app posted by my phone contacts unless they're actually worth seeing there, I want to see reviews based on their usefulness or upvotes and I want to see reviews from total strangers mostly.

How can I achieve this?

OnePlus One, Cyanogen OS 13.1 non-rooted, stock, up to date so far.
Apps including Store, Services, Google+ and everything up to date so far.

Go to People section in Google Play Store:

And unfollow everyone there.

If that doesn't help, go to Settings->Applications. Remove access to Contacts for Google Play Store, clean its Data and Cache, and reboot your device.

If that doesn't help, do the same for Google Play Services.

If that doesn't help, I doubt there is much you can do left. Google Play is not a very customizable application, unfortunately.


How to extract eBooks from google play I've uploaded a lot of ePub files to google play books, assuming I would be able to download them again at any time. I now have a new computer and would like to access them, but Google doesn't seem to allow downloads of eBooks previously uploaded, which seems odd to me.

Since there is no encryption or DRM or anything on them, I figured there must be a way to get them back. Here's what I tried so far:

On my linux computer, I installed virtualbox, and installed an Android system there following this guide.
I logged into my Google Account on my virtual Android device and opened one of the eBooks I would like to get back.
I used the vdfuse utility to mount the .vdi image and navigated to the location where the eBooks are stored, which is /data/data/com.google.android.apps.books/files/accounts/{your google account}/volumes according to this thread.

Now, however, I'm a bit at a loss. If I look at one of the eBooks, they look like this:

./cover.png
./cover_thumbnail.png
./res2
./res2/{some-obscure-id}=
./segments
./segments/html{some-index}

Naturally, I assumed that the segments/html* files would be, well, html files. However, that is not true - they seem to be binary files and just list as data when queried with the linux file utility.

What do I do with these files to get back an ePub? Or should I have taken a different approach to this altogether?

You can make use of Google Takeouts. Just unselect everything except Play books and download your data. You can then view your books. If the books you uploaded were in epub format, you may have to rename the extension of the downloaded books to epub from pdf.


How to manage forwarding email from smartphone? I am not able to find the setting to manage the forwarding option in gmail application.

Where I can manage it from the smartphone with android 4.4.4?

If you want to forward an email open the email, click the three dots in the corner of the message and tap the forward button. If you want to forward all of your emails to another address, there is no option in the app. You can do this via the web with the following instructions: https://support.google.com/mail/answer/10957?hl=en. If you need to set this up over mobile for some reason you can achieve this by selecting the "request desktop site" option.


HTC U Play - No root access after flashing insecure boot image This is my first post here and I hope I am posting it in the right place.

I have modified stock boot image following a few guides on XDA. Now running "id" command in adb shell returns:

root@htc_alpine_uhl:/ # id
id
uid=0(root) gid=0(root) groups=0(root) context=u:r:shell:s0

But I am unable to mount /system as rw or even execute simple tasks like "ls /data/media/0" etc.

I am trying to do all this because there is no custom recovery or any other root process available for this device until now.

Any kind of help will be greatly appreciated. I am new with this stuff so please bear with me.

Thanks for reading.

The correct way to root your phone is to flash a custom recovery then install SuperSU zip, modding the boot will not give you root access until there is a real su binary on the system

Have you checked if su command works on your phone or not?


How do I transfer my data? I am giving my phone in exchange I have bought a Redmi Note 5 on Flipkart and I have a Micromax Canvas Nitro 2 with Android 4.0.4 which I am giving in exchange. How do I transfer my data without taking too long?

First of all this link should help you:
https://support.google.com/android/answer/2819582?hl=en

  There are many applications out there in Play Store. So, you can download and
  save your Apps' data. And if you want to backup your storage files
  then, simply copy the important files or all files from the internal &
  external storage directory to your PC.


Is there an option to remove the "administrative" messages from a whatsapp chat? I'm in a whatsapp group chat that has a fairly large amount of messages, as well as a lot of traffic (people joining and leaving the chat). To help me keep only the messages I actually need I delete all the unneeded messages, but then I get a situation where I have pages on pages filled with administrative messages about people leaving and joining. Is there a way to delete those messages to clear up the chat?

The screen shot is from the web app, but I use it primarily on Android devices.

Unless there's an option to adjust the types of notifications under in app settings or general settings for that app then nothing I can think of. If there is another way I doubt it will be worth the hassle.


Developing Android apps from within Android I want to be able to develop Android applications from my Nexus 6p. Basically, just have a project, and compile it into an installable apk, but from within Android itself.
I have heard of AIDE and Java N-IDE, but neither are satisfactory. The AIDE developers seem to be to greedy for money, and the app rarely works. Java N-IDE cannot seem to compile my app with libraries.

I would prefer to do this from a command line, but it doesn't matter too much. I have adb working on my phone, and I also have aidl and aapt on my phone too.

Thanks!

There's a Premium Key ( Separate App )
I think AIDE Is your best bet !


Samsung S7 - Facebook Messenger Drains A Lot of Data I have the fb messenger app on my phone which I use regularly, but in all the months I've used my phone, I've never surpassed 50 MB per month of data usage for that app.

About 2 weeks ago, I got the Nougat 7 update, and I believe ever since then (it started happening around the same time) my Messenger app has been draining data. Within a week, it used about 500 MB of background data.

Is there anyway I can fix this?

It's very bizzare that messenger using heavy data.

The possibilities are:

• May be you have shared a video to few contacts and it is using data!

• May be you have clicked a big video file and switch to another app(video is still loading and using data to finish it to the end of video).
Or
• Viewing videos frequently shared by someone.

If these things are excluded, it may be a bug.

• See playstore if there is an update.

Or try clearing Cache and Data and log in again then observe data usage.


How do you transfer a programs database to another device I am using the Book Catalog program to scan and enter my collection of books.

This program provides an export/backup and import feature, so I can transfer the entered data onto another device.

But I am wondering now: programs can create databases on one device. Can you transfer these database onto another device ?

More specific, could I buy another Samsung Galaxy (or any other Android powered device) and transfer the database onto it for use with the same program (without the export/import feature ) ?

This only applies if you have root access, as Bryan already pointed out in the comments.

I would suggest using a utility such as TitaniumBackup to completely back-up all your applications and your data. It will be stored on your SD card so that you can transfer its files to another device and restore the backups on there.


How to decrease screen brightness without draining extra battery I am currently using ZenFone 5 now with android OS 5.0. Even though I've set my brightness to the lowest but it is still too bright for me, and it's battery capacity is low too... so is there any ways to decrease my screen brightness so that my phone won't die too fast... sorry for my bad english...

There are two problems you report. One is the excessive screen brightness even at the lowest level that your settings allow. The next is that you want to reduce the battery consumption due to this higher brightness.

If you want the first one but not worried about the second you can try screen filter apps. These will reduce the brightness as perceived by our eyes, but will not do any battery saving stuff.  Please look at the apps similar to Screen Filter

On the other hand if you want power saving as well then probably you should have a rooted device that will allow the apps like Velis Auto Brightness to work.


Using two messaging apps on Ice Cream Sandwich? I want to use Textra for SMS and Handcent for MMS, because they're both top in each class, respectively. I want to use Textra as if it were the only messaging app. Then when I want to send an MMS, I would open Handcent and sent my picture, video, ect. The problem is when I get any kind of message both apps show a popup and a notification. Textra is set as my default but I'm still getting notifications from Handcent. Can I disable notifications within Handcent and accomplish my goal?

Got it, went snooping into Handcent messaging settings and turned off pop up and notifications.

After Full Disk Encryption, are all subsequent new files automatically encrypted? I am not talking about the new Lollipop which encrypts everything by default. The older versions, such as Androd 4.2.1/4.2.2 etc. Suppose you went to settings -> security -> encryption, and chose full disk encryption. All files on disk are now encrypted. Now, if you create a new file on the disk 5 minutes later, would that be automatically encrypted right away, or would you need to encrypt it again using full disk encryption?

First, both encryptions you name are the same – only that Lollipop enforces this automatically on some devices.

Second: it's not the files being encrypted, but the entire partitions – thus everything saved to it ends up in (using simple terms) an "encrypted container". Everything transparent, so you won't notice. No need to re-encrypt.


Factory resetting a locked chinese clone without a built-in recovery (Android 4.4) Being the only knowledgeable person in reach, I was asked by this lady to reset this phone after the owner forgot its password. It's an unnamed model apparently powered by a Spreadtrum SoC and built to imitate the LG G4. Judging by the lockscreen blocked by a Google account password prompt, it seems to run on Android 4.x.

Power + Volume down lands on the screen on the left, which contains just generic test routines.

Power + Volume up gets you into what seems to be the fastboot mode. I'm planning on attempting to flash generic recoveries but I'm slightly wary of USB connecting it to my mission-critical notebook. Either way, I wouldn't know which recovery to flash or, if it comes to, which ROM to flash in it.

Ironically, this might as well be the most secure device I've touched.

Good to know that you have fastboot on it.
I suppose your goal is to wipe the data and reset  and not Porting a recovery or a ROM that it might run.
use the fastboot commands to wipe the userdata and the cache

fastboot erase userdata
fastboot erase cache
 Good Luck!


VNC android app which takes native control of touch as a mouse I've been trying to install a linux distribution onto my android tablet for some time now and have done so but have recently stumbled upon a problem. When connecting the mouse, naturally the app does not support dragging windows or scrolling or right mouse click. I was wondering if there was any way to have these things supported by any VNC app. Either that or an alternative way to install linux as a rom.

VNC Viewer from RealVNC is a bit pricey ($9.99) but probably has the best keyboard/mouse support of any VNC app on Android.


Transforming SMS conversation to Inbox and Sent Items Is it possible for me to receive the SMS not in a conversation style, but in a traditional way like what NOKIA does? Inbox is separated from the Sent items.

Pansi SMS supports inbox-style SMS. In Step 2 of the Setup wizard, you will be asked to choose either:

Do not go into standby when phone is plugged in Possible Duplicate:

Is it possible to configure my S2 so that when it is plugged in, the phone doesn't go into standby?

What version of Android are you running? In CyanogenMod and other versions look in SETTINGS > DEVELOPER OPTIONS > STAY AWAKE / KEEP SCREEN ON WHILE CHARGING

You might also want to take a look at this app, if the options aren't available to you.

Seems like this question has been answered earlier - How do I keep my Android 4.0.3 phone awake when USB connected?


Why does Wifi show an error whenever I try to reconnect (Galaxy Ace)? I'm using a Galaxy Ace.  When I turn off WiFi and try to turn it on again it shows an error.  I need to restart my device for it to work.  Any ideas?

I believe this is a problem with Samsung's UI, TouchWiz; I experienced this on a couple ROMs for my Galaxy S.

I don't know of any way to fix it without replacing your ROM, but I did find that going to Settings -> Wireless and network -> WiFi settings and toggling WiFi there seemed to work.  Settings is a standard Android OS app and thus bypasses whatever problem TouchWiz has when you try to toggle the WiFi from the notification area.


Google Services is killing my battery by keeping phone awake In the last few days my Galaxy S3 has gone from lasting 12-13 hours to about 6 hours. On checking the battery monitor it seems to suggest that the phone is constantly staying awake and that Google Services are to blame.

I was recently experiencing real problems with Google Chrome freezing the phone so I have uninstalled and gone back to the native browser but the battery issue persists...

Has anyone experienced anything similar....is a factory reset the only solution? (Android version 4.1.1)

After trawling through all manner of options I isolated the root cause of this issue.

Within Google Account Sync I had a look at all available settings and the one that seemed to be causing an issue was 'Sync Internet' option which was just constantly running (and appearing to be keeping the phone awake.

Switching this off has got back my battery back to normal.

I still have no idea why my phone was trying to sync the entire internet :-)
