Title: Strange behavior on Nexus 4, Android 5.0.1 (issue with Google Play Services?) Apps don't autostart, Google apps don't work, phone freezes
**Update:** Resetting only the Google Play Services app as has been suggested didn't work for me unfortunately, because (in addition to what I've written below) the "force stop" and "uninstall updates" buttons are greyed out.

I decided to do a factory reset, and so far I haven't had any more issues with Google Play Services, but I still don't know what exactly caused these problems (probably an update).

---

I have a Nexus 4 with Android 5.0.1 (no custom rom), and there have been several issues for a few hours now.

It probably started yesterday when a message popped up 2-3 times (over the course of a few hours) saying that "**Google Play services has stopped working**".

Now, after booting the phone and getting to the lockscreen, the **apps which would usually autostart don't seem to start** (messaging apps, gmail, battery widget app etc.) and it doesn't even connect to a cellular network. WLAN works straight away. Sometimes these apps will start (and it connects to the cellular network) more than half an hour after booting the phone.

I've also noticed that for several minutes after booting, the **list of running apps** contains only Settings, Media, Google Services (not Play services!) and Google Keyboard, and after some time, if Google Play services does show up, it is constantly shown as "restarting".

After using the phone for anything between a few minutes and maybe an hour, it will **freeze and not respond to any touchscreen input**, sometimes saying that the launcher is not responding. Prior to freezing, it will usually start lagging heavily. It will still respond to the power button though. (turn screen on/off, show "power off" dialog)

Additionally, **Google's own apps won't work** even when I try to start them manually (I have tried Play Store, Maps, Gmail, YouTube, News & Weather). They either go to a blank screen or don't open at all. The system seems more likely to freeze after trying to open these apps.

I can open the **settings menu**, but some of the options don't work:
\- About Phone \> System updates: It goes to a blank screen for about a second, and then back to the "About phone" menu.
\- About phone \> Status: works only when connected to a cellular network, otherwise I get a dialog saying that the process com.android.phone has stopped.
(these are the ones I found not to work)

## What I've tried:

* **Disabling the Google Play services app and replacing it with the factory version.**
Doesn't work because in order to do this, I would have to disable "Android Device manager" from being a device administrator, but its checkbox stays checked even after trying to disable it.
(Is it normal that "force stop" and "uninstall updates" are greyed out for Google Play services?)
* **Booting in safe mode.**
Works, but I get the same problems in safe mode.
* **Wiping the cache partition.**
Works, but doesn't fix any of the issues.

What could have caused these issues? I haven't installed any new apps recently. Is there anything else I could try? If not, I guess I'll have to do a factory reset.

# Answer
The uninstall updates and force stop buttons are greyed out because of the device administrator's setting. As you already know, you must uncheck the checkbox for Google Device Manager as device administrator first, afterwards the buttons are active.

I did that a couple of times myself because I have the same problems on my Galaxy S4 with the newest Lollipop. There are two problems, though:

1. Immediatelly after reboot of the phone, this setting takes a while to kick in. Only after one or two minutes the device accepts to remove that device admin setting. So give it some time and several tries.
2. From time to time, after reverting to factory version of Google Play services, they get auto-updated to the newest version again, regardless of the auto-update settings you might have.

I figured out that for me each version of Google Play services of 7.0 and newer definitely *will* crash. Version 6.7.76 is the last one that works for me. You can download and install the APK at apkmirror.com. At least for as long as it takes to auto-update it again...

I had the same problem. I uninstalled the updates to the Google Play Services and replaced it with the version that came with my device. It then auto updated (to the same version I had before) and now it works! It seems like a bug in the update process.

# Question
Title: I did a factory reset to sell my phone, and my photos are still there according to the new owner…
I need help in this strange situation! I did a factory reset and cleared everything in my HTC One X, erased all files and photos, removed **all** accounts, and sold the phone.

Now all my photos (2150!) are **all** back there, as the person who bought it says! How is this possible? and what can I do to completely clear it up? I made sure after the reset that **nothing** was in my phone!

# Answer
You mention Dropbox in the comments area of another answer. Merely deleting Dropbox data is insufficient to cleansing its folders. You MUST dissassociate the device from your account or the deleted items will re-synch to the device when next possible.
Start Dropbox.
Settings \> Unlink device from Dropbox.
If this was not done, or done improperly, I can understand how the recovery occurred to the phone.

# Answer
If you thoroughly checked that nothing was left, that's a strange thing indeed (and I cannot imagine it returned "by itself"). But as a factory-reset usually only deletes/wipes `/cache` and `/data`, the SDCard (internal or external) are not touched in this process, so you might have missed that. Some devices offer to include the SDCard with the wipe/factory-reset, though.

For a real safe clean, however, even a wipe might not be enough, as files still could be restored using appropriate software. So if you're selling your device, you'd better make sure your data is completely nuked: not only "marked deleted", but really removed and overwritten. To achieve this, you can use helpers like Nuke My Phone.

# Answer
Factory reset means deleteing all app and leave just the one that were preinstaled. For the ones that were preinstalled just delete their data, like contacts msgs etc.

If you want to delete all data when you do a factory reset i think it will promt you if you want to delete exdernal sd card to(external sd card witch is actually the internal memory that you use for your photos etc, long story) If you don't have that option there then just go to storage and see if you have there an option to wipe everything.

# Answer
If she has your pictures, you either didn't erase it properly, or the sd card was not connected when you erased everything. Or, if she is really evil, she downloaded a tool that gets back deleted data from the datablock. As you probably know, deleting files actually means that the disk will, instead of actually erasing blocks from disk, give the block free to be written over, which is why tools can be used to get (some of the) data back. Assuming that she would have done this though is quite a stretch, but I'm just mentioning it as a possibilty.

Let that also be a lesson: Always check at least the /Pictures, /DCIM and any application folders you may have with personal data (/Dropbox I guess) and delete the data you may find manually. If you want the files to be unrecoverable, apps exist that actually overwrite "empty" space, like Secure Delete Android (haven't tested it though). See http://www.securedeletion.com/

At this point though, the only thing you can do is ask her to delete the pictures and hope she is a thrustworthy person.

HTC phones are different from other phones and I don't know why that is, but sometimes when you reset the phone a variety of info stays on the phone. I know that for sprint the number can't change unless you put in a special code under one of the settings. I don't remember right now what that may be, but I'm sure that your service provider has run into this when folks swap there phones for whatever reason. Your service provider is the only one with this code. So you may need to ask them. Their techs might be the best source. Why do I know this? Because I have worked for both Sprint and Verizon, but it has been a while.

# Question
Title: Override WhatsApp contact image with the chosen Contact Image
I dislike how people use full body pictures for their contact images when it's a small image. When I link the accounts in my Android, I chose a picture that looks good and helps me identify them easily. But in WhatsApp, when these people chose their profile picture, they override my selection.

Is there a way to fix this?

# Answer
For now there isn't, unless an add-ons for WhatsApp will enable this or they built it in themselves. It's comparable to Facebook, user set their own avatar and this can be seen by friends. This works unlike your contact list in which you control the content and other users have no say in adjusting the content.
> 2 votes

# Answer
There is a way. You can just download Android SDK and do from the console:

`adb push /tmp/newimage.jpg /data/data/com.whatsapp/files/Avatars/XXXXXX@s.whatsapp.net.j`

where `XXXX` is the phone number and `/tmp/newimage.jpg` is the new image you want to replace it with.

Why go back?? Try a factory reset. I have a note 3 Exynos on lollipop and it works really well. IMO the mobile is faster than it used to be on kitkat.

However if you want to downgrade, the download the latest version of kitkat and flash it using Odin.

Edit: Take the downgrade as a last resort since there is no sure way of knowing.. Sorry.

# Question
Title: Is there a way to force apps to use internal memory only?
I have a Sony Xperia U, and my 8GB of memory are divided in three parts: 2GB phone memory, 4 GB internal memory (replacing the MicroSD slot) and 2GB that I haven't really figured out about.

I don't want to mess with repartition. I just want to use each one as they must be used.

The problem is: many apps are optimized to save many things in SD, but for this phone it is not really useful, as it has plenty of space in phone memory! What can I do to make automatic created app data use internal memory **only**, leaving SD (internal, in Xperia U's case) free for my own use?

Edit: Thank you for your answers! John, my device is rooted, so, could you explain further about those permissions, please? Thanks in advance!

# Answer
you say your phone is rooted, it is then possible to change the default installation location that the packagagemanager uses to install apps. this will only work with apps that allow it, as others have already pointed out, apps may choose to ignore the packagemanagers recommendation and install to internal/external anyway even if you choose the opposite. also, big game files in the obb directory are stored where the obb directory actually is located; this is dependent on which phone you use.

to change the default installation directory:

1) use terminal emulator from google play (or, alternatively, enable usb debugging and use adb)

2) in terminal emulator, enter:

```
su

```

accept the superuser request, then try either:

```
pm setInstallLocation X

```

or:

```
pm set-install-location X

```

where X can either be

0 = let packagamanager decide

1 = install on internal by default

2 = install on external by default

# Answer
As Sid encouraged, I'll convert my comment to an answer -- while merging in details from the other comments:

There are mainly two ways the SDCard is addressed from within apps:

1. hardcoded path (e.g. `/sdcard/funnyapp`)
2. using Androids API, i.e. `getExternalStorageDirectory()`

While 1. might fail if the SDCard is mounted to a different place, 2. would lead the app to store things in the "first" SDCard (on devices with internal SDCard, that means internal SDCard, on others external). But both cases share the fact: if the app doesn't offer a configuration option, there's nothing you can do to change that. Android does not offer a corresponding setting, and Symlinks don't work on SDCards (due to file system limitations).

Same applies to the storage used for the app itself, as Sid wrote pointing to Android support documents (see also the developers documentation on App Install Location for this). While in most cases one can move an app using the App2SD feature built into Android, the developer can overrule this so his app cannot be moved.

As for John's comment, this wouldn't really work. Still a little explanation on what he most likely meant: Using "root powers", you could change ownership of all files and directories. So his idea probably was to make all things on your SDCard owned by root, and only readable to others. This wouldn't work for multiple reasons:

* This would make things even more complicated to you (as you couldn't write either without becoming root before, every single time).
* You could not do that on directory level (e.g. doing it for every single directory except for one with a "fantasy name" like e.g. "MyOwnDocs", where you could store your stuff without the trouble from the previous argument), as the file system on the card (FAT) does not support that.
* It *could* somehow if you use a script to remount the card read-write each time when you want to write to it, and make it read-only again once you're done. But again, this complication most likely isn't worth it. In addition, some apps might crash with a read-only SDCard, as they (for good reasons) don't expect an SDCard present but not writable.

## TL;DR

So in short: If the apps cannot be configured such themselves, there's no way to accomplish this (except for re-writing those apps).

# Question
Title: My Samsung Note 8.0 GT-N5100 is stuck in a boot loop. I want to retrieve data ... is there any hope?
I am about to press "wipe data/factory reset" on the recovery menu, but have found this place and you are my last best hope!

I hope to rescue data from S-note and other apps, plus loads of photos and videos (although these are mainly backed up on google+)

I am not an expert but can and will follow difficult instructions if you explain them slowly!

Thank you for your time.

# Answer
I tried various suggestions to get past the bootloop but could not even get into safe mode. All I had to work with were the options on the recovery menu. Clearing the cache partition seemed to make no difference, so I eventually gave up and selected wipe data/factory reset.

This also seemed top have no effect. However, the device unexpectedly closed itself down and when I restarted it, there were signs of life and it booted up again for the first time for weeks!

I went through the start-up procedures carefully and selected "restore" for any google/ Samsung data and applications, even though it said I had not backed any up ... and it seems that all my data has not been lost after all! I already knew that my pics and vids were on google+ so was not too disappointed to find quite an empty gallery, but was delighted to find ALL my S-note docs were restored, and a number of my apps.

Some - quite a few - are missing - all my kindle ebooks for example, but I will see if these are transferrable, and there are apps I can find again if I need them.

I would recommend anyone with a Samsung device to have a Samsung account and enable "back-up" - also to save as much data as poss onto the micro sim card.

Thanks to Izzy and everyone for helping me through this traumatic afternoon!

# Answer
If I'm not mistaken, for pics and videos, I believe you should be able to plug it into a pc using a USB cable and move the folders you want to a backup directory. For App data it may be hit and miss, some you may be able to find, but some will not be recoverable. Here are links that may be helpful to finding S-note related files:

Title: How to stop erase of data after clicking erase option mistakenly in android device manager
I have lost my motog2 mobile and mistakenly pressed to erase the data after using the option lock of android device manager.And later on got to know that the option deletes total data and I will not be able to atleast track my mobile location.so I want to stop the erase option to perform, before my mobile got internet connection and got data erased.please suggest a way for this.

# Answer

Unfortunately, if you issued the command to erase the phone, there is no taking it back.

If the device you sent the erase command to does not have service, it would not receive the command; but then you would not be able to track the disconnected device either.

Once it gets an internet connection, and receives the command to erase, it will start.

If you happen to find the device prior to it receiving the command to erase, you may be able to remove Android Device Manager to prevent loss of data.

You're probably going to need to specify *exactly* what model phone you have, because not all phones bootstrap the same way.

In *general*, however, if you can't get the phone to go into it's equivalent of Download/Odin mode (where it simply doesn't do anything except listen over USB for an upload of a firmware file) with the majority of the phones on the market, you're *done*. There's pretty much nothing else to do that wouldn't require special hardware.

# Answer

Ok first, antivirus in the classical sense is almost useless on android. Due to the strong security sandboxing, antivirus apps can only detect malicious apps based on signatures but cannot stop or remove them. So you need to take care yourself to get rid of the malware.

Second, viruses in the classical sense also rarely exist on android, so please provide more infos on what exactly your malware is doing. If I got you right, you have some problem with blocked/filled up storage.

Third, just to exclude something completely independent of malware activity, did you ever use the newly inserted sd card in an android phone? You may need to format the card before it can be used, see storage settings.

Summary: please check if your sd card is properly formatted and also provide more details on your problem and the malware you assume you have on your phone.

# Question
Title: if I know nothing about Android, is it crazy to have a rooted phone?
I bought my first Android phone off ebay, a Samsung Galaxy S4 after always using Windows phones. It was supposed to be unlocked and a "store demo", but when I started playing with it, I was getting warnings that it was rooted and couldn't update in the regular way, etc.

I tried to update using Samsung Kies, which gave me a ton of errors, I had to do it four times. This was the error message I kept getting:

http://i136.photobucket.com/albums/q161/Arylkin/1%20error.jpg

Then I got an error that I needed to do "emergency firmware recovery":

http://i136.photobucket.com/albums/q161/Arylkin/error%202.jpg

I finally got it to work (I don't know what kind of update it was, because it's still running the same Android version after it). I got it to work by just ignoring the emergency recovery message and hitting continue (or something).

I am apprehensive about keeping this phone, since while I really do like it, I am worried about having some fiasco and it refusing to update down the road. Also, every tutorial about rooting and "flashing roms" (whatever that means) and doing anything to a rooted phone says, "WARNING- YOU MIGHT JUST BRICK YOUR PHONE!". Needless to say, this worries me.

The seller is willing to take it back, but now I've already bought a otterbox case for the S4 as well as additional batteries, so I'm kind of roped in to having an S4.

What would you do, return it and try to find another person selling an S4 that is stock? I really don't know anything about Android, and even after reading tutorials, I'm not really comfortable doing a bunch of stuff to the command line of my phone or whatever, particularly since there are 1,000 warnings that doing so might totally break it.

Even video tutorials on rerooting or whatever have a bunch of comments like, "Now my phone is broken! Thanks a lot!" Everything I read says how rooting is the coolest ever, but I really don't want to break it since I will not be able to replace this, financially.

I'd appreciate any words of wisdom!

# Answer
> 2 votes
If it's rooted, leave it be. It's very unlikely for the S4 to receive many (if any) more Android OS updates officially since it's now a couple of generations old. I use a rooted S4 myself, and love the fact that I can remove bloatware at will and make backups of *everything*.

With that being said, some more info from your device might help us direct you to info on your particular ROM if you have one, and how to lock it back down if you still so desire. Go into Settings\>About Phone and see what Android version you're running and the build number for starters. All of those scary warnings in forums are there for a reason: with root you have unrestrained access to the very innards of your phone. If you start changing things in *certain* areas you can mess things up. However, it generally takes more than doing everyday tasks to do it.

Armed with the information from the About Phone section, head over to the XDA Forums to find out just about anything you'd ever want to know about that phone, along with some generally very knowledgeable and helpful people.

If it's already rooted, I wouldn't worry about it. I wouldn't let it do any OTA updates, though. I rooted my first phone without knowing much about it, and it was fine. I use root mainly for apps like Titanium Backup, which is just great. You can backup and save all your apps and app data, as well as remove any bloatware that normally comes with the phone. You can actually get rid of all the apps you don't want/use.

When I rooted my S4, my phone stopped getting the OTA updates. If it's important to you to have the latest and greatest version of android, then yeah, you might want to get rid of it or unroot it. If you don't want to deal with the hassle and like you phone the way it is, I would keep it.

I would definitely check out these forums here. Who knows, you might find a new hobby.

# Answer

What are the output specs of the charger?

With a different amperage, there's no risk unless the amperage is very high. A different voltage might cause problems. Modern devices need 5V and anywhere between 500mA to 2A. Don't try something like 9V. Also, using high amperage to charge is not good for long term health of the battery.

Title: terminal on real android device from PC
I want to run terminal on my device however the small screen is very inconvenient. I wondering if it is possible to run terminal on real android device from PC?

# Answer
You can use Android Debug Bridge (ADB) shell to issue basic Linux commands on your phone, just like you would in a terminal emulator app. To install you'll need to do the following:

1. On the phone go to `Settings -> About phone`, and tap on "Build number" seven times. This enabled Developer tools.
2. Go back to the main Settings screen and you should now see `Developer options` under the "System" section.
3. Go to `Developer options`, enable "Android debugging" option, and then tap `OK` on the verification prompt.
4. On your PC download the Android SDK Tools from here. You can either download the whole SDK, or just the stuff necessary to connect to your phone, which is on the same page, under "Download for other platforms -\> SDK Tools Only" section.
5. Install the tools you just downloaded.
6. Download and install the USB drivers for your phone (usually provided by the manufacturer.)
7. Re-connect your phone to the PC with a USB cable.
8. Open Command prompt (assuming Windows,) navigate to where you installed the SDK tools (e.g. "C:\android-sdk\platform-tools\\") and type in the following: `adb devices`
9. If all of the above was done successfully, a prompt should pop up asking you to allow connections from this computer. Accept the pairing request, and the prompt should show your phone's ID. If this doesn't happen - it usually means that the drivers aren't installed correctly.
10. Back at Command prompt, type in `adb shell` and press Enter, and you should be connected to the phone's terminal.

This should get you started. ADB commands are listed on Google's site here. The shell provides some basic Linux commands like `ls`, `cp`, etc. Be aware that most file and device management commands will require root (i.e. elevated privileges,) which is a separate topic.

# Answer
Alternatively to the ADB variant described by Chahk (which requires at least a minal installation of ADB on your computer), you can install a SSH server app on your device (examples include, but are not restricted to, SSH Server, DigiSSHD, Servers Ultimate). Then you can use the `ssh` command on Linux/Mac, or a tool like PuTTY on Windows, to connect to your device and run shell commands, as if you were using a terminal app on the device itself.

    Download PuTTY.exe for SSH Client on your windows PC, it comes in single executable file so you don’t need to install that just double click on that and PuTTY will start.

    There is no need to setting up any thing in PuTTY.

```

**Let’s start**

```
First step is to running Wi-Fi and connect your android phone to target PC, then run SSHDroid server into your mobile phone, but before that make sure under the SSHDroid’s application window click Options -> “Require WiFi” is checked as seen on above pic screen 2. And then click “start” option.
Once SSH server is successfully started it will show IP address of your mobile phone in light sky color like this root@192.168.43.129 as seen on screen 4.
Take the IP “192.168.43.129” and type it to your PuTTY program’s (PC) host field and hit connect. Make sure port number is 22 as seen in second pic.
It will ask for certification click ok and then command line log-in window will appear, type “root” hit enter and then type the password for root user, default is “admin” as i mentioned before. After successful log-in you will be able to use Linux commands like ls, reboot -f, mkdir, find, etc.

```

if your phone is connected to internet you can also use network commands like ping, wget, telnet etc.

# Question
Title: What happens when you connect an Android phone to another Android phone?
I've just connected my HTC Butterfly to a Galaxy Note 3 (micro-USB to female USB -\> Male USB to micro-USB)...

And nothing really happened. What is supposed to happen? Am I able to view the other phones' storage, and vica versa? It did say something regarding keyboard(s), assuming it thought it was a keyboard?

I've been doing a couple of tests, using file manager, trying to transfer files, play music, etc... But nothing seems to work.

Is it possible to transfer files like that? (Not that it's handy; I just want to know if it's possible.)

# Answer
Yes, it is possible to transfer using an OTG cable. But you require at least one of the phones to support OTG, and it is better explained here. The phones mentioned in the post are Xperia and Micromax. I am sure it will work with the rest of the OTG-supported phones too.

# Question
Title: Transfer root to SDcard with switch_root didn't work
I'm trying to install Debian on the Android 4.4 (modded with cyanogenmod) that's installed on my nexus 10 to one external sd card. I'm reading this tutorial :

http://whiteboard.ping.se/Android/Debian

I've attached the Leef microSD microUSB Connector with a 64GB sd card inside to the mini usb port of my nexus 10 as you can see here :

The tutorial talks about the The ASUS Transformer TF101 and the instructions are based on this tablet. Instead I have a tablet nexus 10,that's equipped with an internal sd card where I have installed android 4.4 + cyanogenmod. For this reason I need to know how to change some part of the tutorial to adapt it to my situation. Anyway on my desktop computer I have partitioned the sd card in this way :

```
Disk /dev/sdf: 64.0 GB, 64021856256 bytes
255 heads, 63 sectors/track, 7783 cylinders, total 125042688 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0004504c

   Device Boot      Start         End      Blocks   Id  System
/dev/sdf1            2048    32767999    16382976    b  W95 FAT32
/dev/sdf2        32768000   125042687    46137344   83  Linux

```

My nexus 10 recognizes the sd card as sda2. According with the tutorial I have issued the following commands,but something did not work :

```
mount -o rw,remount /
mkdir /mnt/deb
mount -t ext4 /dev/block/sda2 /mnt/deb
/mnt/deb/busybox sh
/mnt/deb/busybox mount -t proc none /mnt/deb/proc
/mnt/deb/busybox mount -t sysfs none /mnt/deb/sys
/mnt/deb/busybox mount -t tmpfs none /mnt/deb/dev
/mnt/deb/busybox mdev -s
exec /mnt/deb/busybox switch_root /mnt/deb /init

BusyBox v1.21.1 (2013-07-08 10:07:37 CDT) multi-call binary.

Usage: switch_root [-c /dev/console] NEW_ROOT NEW_INIT [ARGS]

Free initramfs and switch to another root fs:
chroot to NEW_ROOT, delete all in /, move NEW_ROOT to /,
execute NEW_INIT. PID must be 1. NEW_ROOT must be a mountpoint.

        -c DEV  Reopen stdio to DEV after switch

```

but where is the mistake ?

# Answer

busybox switch\_root works only when called from PID 1, meaning from init.

# Question
Title: Missed call notification shown even in auto rejecting or deliberate rejection?
I have a Galaxy Note 8.0 N5100 tablet which is updated to the latest version of Android (4.2.2) using the following official ROM from SAMMOBILE.

My problem is even when I deliberately reject someone's calling, there's a notification shown like this:

This is really annoying for me because I have put someone in my auto rejection list, but whenever he calls, this notification is shown.

I did factory reset, and now the problem is fixed. But can anyone help me pointing what was wrong? Is it because of the Android update?

# Answer
Problem is fixed. The answer is I had "Any.do" app on my device. I feel like a fool now because instead of thinking about uninstalling an app, I thought that it may be a software bug so I updated my Android version.

Title: How to use Tasker to answer a private number, play an audio file to the caller and hang up?
I would like Tasker to answer any private number (without the audio playing through my phone's speaker) and play an audio file (an MP3 that says, "this phone does not accept calls from private numbers") and then disconnect the call.

Can someone help me set up a Tasker profile for this?

# Answer
Very few, if any, devices supports playing sound directly to the phone (voice) call audio stream.

Try playing a sound in Tasker using the Play Ringtone action to the Voice call audio stream, to see if your device support it.

# Answer

You should be able to get this information from your network provider as they will have a list of IMEI numbers that have been used by your sim card depending on the system that their customer care is using. They may need to contact a higher department in order to get this information for you.

# Answer
> 2 votes
Do you still have the packaging for the phone? The IMEI number should be printed on the packaging.

Alternatively if you used a Google account on your device, you can get it from accessing the dashboard and going down to `Android`. Your IMEI should be displayed there.

# Answer

IMEI number is also available on the bottom of the box in which you have received you phone.

# Answer

Look on the original box of your phone. There you should find the IMEI number on a sticker. Good luck with finding your phone :-)

However you can also go to https://www.google.com/settings/dashboard and login with the account used on your phone and then go to 'Android'. There you will see all your Android devices and you IMEI numbers.

With Changelog Droid being *currently* "out of order"1, let me mention an alternative:

**App Watcher** claims to do the very same:

> App Watcher notifies you about updates of applications from Play Store even the app is not installed currently on your device and provides quick access to the "What's new" section.

*App Watcher* (source: Google Play; click images for larger variants)

**1:** (according to a comment from winchendonsprings); by a response I've got from the dev, he's quite busy with other tasks at the moment, but did not abandon the app – he still plans to update it, but cannot give an estimate.

It's very simple. Connect your phone to your computer, search for the Whatsapp directory (just called Whatsapp), and just copy it to your computer. Everything you wanted is stored in that folder.

When you want to restore your backup, you just copy the folder back to the phone **and then** install Whatsapp. You will then be given the option to restore backup.

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

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

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

However, from my understanding, since Wi-Fi Direct is supported it shouldn't be extremely hard for someone to get Miracast working on the device. This has been done for the regular SGS2, though I do not completely understand those posts.
> 1 votes

# Answer
Yes it does, but probably not on the official ROMs. It is working on CM12 and recent CM11-based ROMs. The broadcom chip inside galaxy s2 plus supports multi-role (but with probably newer drivers), so it even doesn't disconnect from wifi while it is mirroring.

# Question
Title: nexus 5 android 5.1 installing
I am trying to upgrade my Nexus 6 with version 5.0.1 (Build number LRX22C) via OTA to Android 5.1.

The OTA update is downloaded successfully and after pressing "Restart & Install" I see a dead droid with the message "Error!".

The phone was rooted and I unrooted it via SuperSU. Did not help. Wiping cache partition also did not change anything.

# Answer
> 1 votes
Since Android 5, OTA installs verify each partition as a whole so any changes will result in verification failing even if the file is not changed by the update. You said that you unrooted via SuperSU but it is likely that there is something that has changed in the `system` partition. Usually the error message will indicate the file that has caused it to fail.

Therefore, your options are to restore the `system` partition to the 'stock' state (removing any files you've added, reverting any changes to files and re-instating any deleted files) and flash the OTA or flash a factory image using the steps in this answer (using the 5.1 file names in place of the 4.3 ones in that answer)

# Question
Title: Does android switch to a different APN when in hotspot mode?
I've tried turning on the portable hot-spot mode on my nexus-one and got a message from my operator saying that my plan doesn't cover data traffic made through the `web.operator.com` APN, as opposed to `mobile.operator.com` (my "usual" APN). That made me curious. Does that mean that android switches APNs when the hot-spot feature is active? And if so, is this a built-in feature/configuration option or an operator customization?

**Update** No, the phone doesn't switch to a different APN, but I'm still not sure what triggered the message from my operator...

**Update** There's kind of a persistent rumor that European Nexus-One phones get tweaked OSes, see the xda-developers forum threads \[1\] and \[2\], or google nexus-one forums \[1\] and \[2\]. One of the most likely tweaks seems to be the tagging of hotspot traffic, in order to be able to charge for it differently.

# Answer
> 1 votes
Also see http://forum.xda-developers.com/showthread.php?t=734138 for a discussion about how they might. Mechanisms other than APN change might include

* Time to live
* Request header
* Data volume

Answer seems to be probably not.

# Answer
> 1 votes
Yes, Android phones indeed switch to another APN when the hotspot mode is activated. I have deleted all default APNs and replaced it with just one, hey presto, managed to transfer 128GB of personal hotspot when I only have 1GB.

# Question
Title: CyanogenMod for Samsung Galaxy S Advance. Which version?
Which version of CyanogenMod should I use for Samsung Galaxy S Advance and where should I download it from? I'm interested in CyanogenMod 11 but maybe there is a better choice? I wouldn't like to download wrong version so I'll be grateful for exact link. Thank you.

# Answer
The Galaxy S Advance is not officially supported by CyanogenMod. They provide links to several unofficial ports on their wiki, however:

Since these are not officially provided by the CM team, they may not contain all of the features/changes in a supported build, and you would need to contact the developer of the build directly if you experience issues.

# Question
Title: Are in-app-purchases applied after an app reinstall?
If I purchase an in-app-purchase (e.g., in-game currency or content) and I will remove the app and install it later, will the in-app-purchase content still be accessible?

For example:

* Plants VS Zombie 2 Coins
* Where's my Water additional content

# Answer
In general, yes. The content you purchased via an in-app-purchase will persist between installs (and even across devices). The purchase is tied to the account and will usually be restored upon installing the app again.

There may be rare cases, where the developer has not done this; but for the most part they do.

# Question
Title: Get rid of toast message when Spotify Track changes
I am trying to figure out how to get rid of a toast message that pops up whenever a family member changes tracks in her Spotify app on her Galaxy S5 (Android 5.0). It seems that most of the time when the track changes (either because the song ended or because she changed tracks), she would usually (but not always) get a toast message that says: `MP:com.samsung.MusicPlayer.playstatechanged`

I would appreciate any advice on how to get rid of this toast message.

# Answer
From the toast message,

> MP:com.samsung.MusicPlayer.playstatechanged

and comparing to a source code, it seems that the user is using Simple Last.fm Scrobbler.

The app also supports many music players, such as

> Supported apps: Android Music Player, HTC Hero/Sense Music Player, Google Music, PlayerPro, Meridian Player, MixZing, Archos Music Player, Rhapsody Android, Vanilla Music Player, bTunes, ³ (cubed), WIMP, Zimly, Just Playlists, PowerAMP, Winamp, myTouch 4G, RockOn, jukefox, DAAP Media Player, Folder Player, GoneMAD Music Player, MIUI Music Player, ServeStream, Default Sony Ericsson/Xperia Music Player, Neutron Music Player, Music2Dance2, Rdio, DeaDBeeF, Music Pump XBMC Remote (Beta), JRTStudio Android Music Player, Music Folder Player, Apollo, LG Music Player, Now Playing, Shuttle Music Player, My Cloud Player, SoundSeeder, Amazon Music, more...

Uninstalling the app will remove the toast message when playing musics with listed players.

Title: Turn on screen during notification on Moto G
Before I had an HTC one with 4.x & 5.x with custom roms. Whenever I got a text message and my phone had the screen off, the screen would turn on. I didn't think this was special behavior.

I just bought a Moto G (2nd Gen) with 5.x but when I get a text message the screen stays off.

I downloaded an app called AcDisplay and this helps, but it is a suboptimal solution since it shows its own screen and not the default android lock screen.

Is the turn on screen during notification only on custom roms?

This is hard to search for since nearly all results are for adjusting the privacy of the notifications that show on the lock screen.

Go to settings....display...then turn on he option "ambient display" It wakes the screen when notifications arrive!

I had the same problem before.

Then try rooting again.

# Question
Title: Android phone keeps rebooting, how can I save my data?
I hope this question fits this site, as in my opinion the problem is caused by Android.

My problem is that my phone froze all of the sudden while browsing settings, and ever since the first freeze it reboots all the time. It boots just fine, but after a short period it freezes then reboots again, in a loop.

I tried to leave my phone until the battery drains, then take it out for a day, but the issue is still present. I wiped the cache partition from recovery mode, the reboot is still occurs even in safe mode.

**UPDATE:** **Safe mode seems to be working, at least I can browse my phone without it freezing. However it freezes in safe mode if I go to the "Application manager" in settings, thus I can't uninstall any applications.**

I've read that a hard (factory) reset would probably solve the problem, however I have important information on my phone (contacts, messages, pictures) which I don't want to lose.

Since I assume that the hard reset would solve my problem, my question is, how can I save my data from the phone? Is there any utility that allows me to directly copy from the phone?

* **Phone:** Samsung Galaxy Ace 2 (i8160)
* **Android version:** 4.1.2
* **Kernel version:** 3.0.31-1106830

The phone is **not rooted** or tinkered with in any way.

I know there are already similar question on this site, however they did not receive a working answer, and I feel like my situation might be a different issue.

# Answer
I'm sorry, but at this point your only hope is a factory reset.

The symptoms sound like the data for one of the system apps has become corrupted. If you had any way to stop the reboot cycle, you'd have a shot at saving the data. Since even safe mode doesn't give you that, there's not much you can do.

I will suggest, for the future, saving all of your contacts, messages, phone logs, *et al.*, to external servers, such as Google Contacts. That will also help when you upgrade your phone. There are several apps in the Google Play store to save text messages, phone logs, photos, videos, and the like to a remote server.

# Question
Title: Android-System causes my smartphone to lag
The Process `Àndroid-System` causes my Smartphone to lag very often since it uses much CPU and drains my battery. Restart does not work. There is no other process using as much CPU.

MediaServer seems not to be the problem.

Phone: LG G2 "LG-D802"

Android 4.4.2

Kernel 3.4.0

How can I fix this problem?

# Answer
What you're seeing is probably not Android System itself, but rather MediaServer, which in case you download a corrupted file might cause problems.

I would recommend trying to delete whatever you downloaded in the past few days, and in case that doesn't work, perform a factory reset.

# Question
Title: How can I view SSL certificate information (the padlock popup in Chrome desktop) in Chrome Mobile?
When I'm on my Desktop Chrome, I can click on the padlock icon in the address bar and see the information about my SSL connection, like the TLS version, the certificate strength, the authority that issued the certificate, and whether there's unsecured content on the website.

Is there a way to view this information on Chrome Mobile on an Android device? In case it matters, the Android version is 4.4.2, but will likely soon change to 5.0, but if it's different for both versions, I'm interested in both methods.

I tried just tapping on the padlock icon in the address bar, but it just gives the url and "your connection is private" and an option to copy the URL.

To clarify: this is all that I see when tapping the padlock:

<sub>(Click image to enlarge)</sub>

No mention of SSL version or similar stuff.

# Answer
The page info was simplified as the security information was cryptic for "most users": https://code.google.com/p/chromium/issues/detail?id=302561

A subsequent issue has been raised to reimplement more detailed connection info: https://code.google.com/p/chromium/issues/detail?id=425158

The latter issue has reportedly been started/assigned, so hopefully this will be fixed soon.

**EDIT:** Chrome 44 for Android has now been released (as stable). This reintroduces the connection info.

2. Open Settings, Select Apps, find the app in the list of apps, and select "Uninstall" or
3. Open Settings, Select Apps, find the app in the list of apps, and select "Clear Cache", then "Clear Data", then "Uninstall"

Specifically, does any of these options leave more behind than another option (or written conversely, does any one of these options do a better job cleaning up during an uninstall)?

According to my experiences,

you just need the `Region Rom` for your `Operator and Country` and flash the Modem in your phone.and of course, if you have any backup of `Efs`, just restore or flash it.

also, try to download stock rom for your region and then test it.

hope this fixed. else,

maybe you need the `BoX` for fix this.

Title: "Signature Verification Failed" when flashing stock ROM
When booting into recovery mode and installing a ROM zip from my SDcard, it first says I need to mount my /sdcard (when it is mounted), and then it says "signature verification failed", despite my using a stock ROM zip.

Perhaps this has something to do with my obtaining the stock(?) ROM from a possibly untrustworthy third-party site? What is the official download site for Samsung Galaxy S4 (SGH-M919) phones?

thanks in advance for the help

(cf. my other question for more background information)

I have found sammobile.com a very useful site for finding firmware for samsung devices. I don't think there is an official download site. Here is the firmware for SGH-M919

I have had the same issue before. Just trying **the same** process again fixed it for me.
You can try wiping your cache and dalvik cache but I am not sure if that will make a difference. Then retry flashing the ROM.
Also make sure you have downloaded the file correctly. Trying to Install a partially downloaded file will give you a lot of headaches!

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

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

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

My questions are:

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

Thanks everyone!

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

Boot into android stock recovery.

```
Power + Home + Vol. Up

```

Scroll down to backup internal data.

Remove the SD card.

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

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

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

Can you not make your own?

Open up paint or photoshop of some sort and fill an area black. Save the image as a png and then place on your phones memory card. Then on the phone set your wallpaper from the gallery and select the black image.

# Answer

The simplest way to create a black image is to keep the phone with camera down on desk (so that no light falls on the camera) and shooting an image.

Then simply set the recently shot image as your wall paper. :)

*Disclaimer: I am one of the developers*, and super excited to announce that we just published a new app for this!

We focused on making it simple and really good looking to change your wallpaper to a solid color of your choice within the palette of Android Lollipop material colors. You can find the app in Google Play: Material Colors Wallpaper HD

Have a nice one :)

# Question
Title: Cannot report app crashes
In the rare event that I get an app crash notification (unfortunately "app" has stopped working), I am never able to report the event. When I press the report button, I get a second notification, this time that Play Store has stopped.

In all other respects Play Store works fine.

This sequence of events always occurs no matter what app originally crashed.

I have already tried clearing Google Play cache and data. I tried removing its updates. I tried reinstalling its updates.

I am running Kitkat on an AT&T supplied Samsung Galaxy S3 mini. Kitkat was an AT&T push upgrade.

I keep some system apps turned off: notably just about anything starting with AT&T or Samsung.

What could I be doing wrong?

# Answer
If you want to report crash, you can do using other way :

When app crash, go to

> Phone Dialer -\> Dial \*#9900# keystring -\> Dial

This will open Dumpsys terminal, then click Run Dumpstate and this application terminal will capture logs in background for you.

Now, you just need to attach the file from /log/dumpstate\_ddmmyyhhmmss file as crash report.

title: How to update timezone data?

text:
# Question
Title: How to update timezone data?
As you might listened, Russian government loves to change the law about timezones in Russia every couple of years. It causes situation when one year we have daylight savings time, but another year we don't have it.

I use Huawei G700 with rooted Android 4.2 with timezones issue: if I enable clock synchronization via GPS on menu, my Android's clock goes wrong for extra hour; it disables synchronization and sets up right time by hands, I see wrong timestamps in messaging apps, like I'm writing from the future.

The system timezone sets up right, to Moscow Standard Time, but the `tzdata` itself in the Android is obsolete, I guess. TimeZone Changer doesn't help - it shows that my timezone is Moscow, and if I change it to Moscow, nothing really changes =)

So -

* how could I know current `tzdata` version used by Android, and
* how could I update it?

**Edit:** I searched for something related to `tzdata` on my Android file system and found file `/system/usr/share/zoneinfo/zoneinfo.version` with content "2012h" - it looks like `tzdata` version. There are also 2 other files in this dir - `zoneinfo.idx` and `zoneinfo.dat`, but their content doesn't looks as `tzdata`.

**Edit2:** currently choosen timezone (not it's offset, but timezone itself!) could be found by typing `getprop persist.sys.timezone` in terminal emulator.

# Answer
> 2 votes
Yeah, it seems that `/system/usr/share/zoneinfo/zoneinfo.*` files is tzdata in java format. I tried to use TimeZone Fixer \- it replaced all those 3 files. After rebooting device and enable clock synchronization via GPS on system menu, I get right time. Messaging apps now show right time too.

So, using "TimeZone Fixer" app is likely solves my issue - but app description says it could cause unable-to-boot state for some Android versions.

# Question
Title: Dismissing an upcoming alarm when a Calendar notification is present
I had my Nexus 5 updated to Android 5.0 recently. I notice the following "interesting" behavior of the new notification system in Android 5.0.

As you know, when there is an upcoming alarm the stock Alarm app displays an advance notification, offering the opportunity to dismiss the alarm before it happens. The notification is a rectangle, saying "Upcoming alarm" and stating the next alarm time and name. It normally has a "DISMISS NOW" link at the bottom.

The stock Calendar application also displays Android notifications for upcoming evens, if an advance pop-up notification is requested in event settings.

However, if the Alarm notification comes up **together** with a Calendar notification (i.e. they are stacked one above the other in the notification screen), the "DISMISS NOW" option is always missing from Alarm notification. The upcoming alarm notification looks as usual (a rectangle with future alarm time and name), but there's no "DISMISS NOW" link at the bottom.

Calendar is the only app I discovered so far, whose notifications have this effect on Alarm notifications. For example, GMail notifications can co-exist with Alarm notifications: they do not make the "DISMISS NOW" option to disappear from Alarm notifications.

So, what exactly is the idea behind this strange user interface behavior? Is this a bug? Or is this by design? Is there a trick for dismissing upcoming alarms in a situation when the Alarm notification shows no "DISMISS NOW" option?

# Answer
> 2 votes
Swipe down from the alarm notification itself to expand it (not from the top of the screen to get to quick settings). It will expand other notifications, too, to see the body of an email, or the contents of a chat message. For pending alarms, it will show the dismiss button.

I was seeing far more sporadic behavior as to when it showed up and when it didn't.

# Question
Title: Google Voice question
I'm traveling internationally soon and will have unlimited internet usage but regular calling/texting will be restricted or I'll have high roaming charges. So I'm wondering how Google Voice works... is it like a relay where someone calls my Google Voice number and and then Google calls my regular number to complete the call? Or is it pure voip and will work through internet service alone? And will call quality suffer/improve depending on internet quality/speed? Thanks in advance

# Answer
> 0 votes
A Google Voice number forwards any calls it gets (and I believe texts) to numbers you set up. There is an option where all calls to that number can also ring in Google Hangouts.

If you are travelling, you could download Hangouts on your phone and make a temporary Google Voice number forwarding calls to your home phone. When the number gets a call it will ring your home phone and in your Hangouts app if your phone has access to internet.

If you choose to answer it in Hangouts, it's the same as having an internet call with the person who called you. Call quality will suffer/improve depending on internet quality/speed.

If you are going out of US/Canada, I don't know if you will be charged for calls. Most questions can be answered here

# Question
Title: "Unable to forget Hot Spot" - Can't disconnect from it either
I am running stock kitkat (4.4.4). There are some hotspots my phone will connect to whenever I am near. If I try to disconnect from it, I get an error message that says:

`Unable to forget Hot Spot` (sic).

My only options are to disable WiFi or keep connected.

If I am not near that hotspot, *it won't even show up on the list of memorized hotspots*.

What is happening here?

# Answer
These are probably hotspots set up by your carrier, designed to reduce load on their 3G/4G network by offloading some of it to WiFi. You would not be able to prevent using these unless you turn off WiFi (why is that a problem for you?) or root / use a custom firmware.

# Question
Title: How to disable GPS if not in use?
Is there a way to disable GPS if not in use by any app – either provided by Android itself or, if that's not possible, by use of a third-party app?

# Answer
> 5 votes
GPS is automatically turned-off when not in use by apps. That said, apps can use GPS even if they work in background. So, I guess that your concern should be checking the apps that use GPS in the background, rather than turning it off completely.

# Answer
> 0 votes
As Aleks pointed out, GPS only "drains battery" when accessed – its battery use in standby is negligible (see my answer here for some statistics). You can see whenever some app is accessing it, as then the cross-hair GPS icon appears in the notification bar.

However, some (badly coded) apps might be "hammering" GPS for location details. If you encounter such an app (but cannot live without that particular one), there are some tools which can take care for that (see e.g. our tag-wiki) – and e.g. turn GPS of as soon as that "waster" starts, or after a delay of say 1 min to allow it for one fix and not more.

# Answer

The `Lost.dir` is a ***system folder***. Its a place where the Android OS places files that were recovered **during a system boot up**.

**lost.dir in android**

---

**What is the folder for?**

> Its quite evident that there is no application named LOST.DIR installed on your device. At times the folder's size can range in gigabytes. In such situations one may wonder about the contents of the folder and its use, and whether it is safe to delete the folder to save memory.

**Can I delete the contents of LOST.DIR ?**

> In order to save precious memory space its completely normal to delete the contents of LOST.DIR as it only acts as a recycle bin. You can also delete the LOST.DIR folder itself but it will reappear the next time the system boots up. When your Android system throws up a message saying 'Preparing external SD card' its actually checking the contents of LOST.DIR, and if it fails to locate the directory, it creates one.

Title: 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?

# Answer

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.

Title: Tablet touchscreen too sensitive
My tablet (Asus TF300T) has been starting to show sensitivity issues. It repeatedly shows touch moves that aren't there, such as these: (this screenshot was taken using the debugging option for showing touch input)

It started out with an occasional movement that was already annoying, but it went worse: these dozen concurrent presses are persisting, moving and raising in amount: The tablet is uncontrollable now. **Is there a way to turn down the sensitivity so that these fake fingers don't show up or to turn the touchscreen off completely?**

Although the tablet itself isn't accessible anymore, USB debugging is turned on, the tablet is not rooted. Standard Rom, updated to 4.2.

# Answer

No, there's no setting for the sensitivity. The touchscreen controller already filters the input it gets from the screen itself, so probably you wouldn't be able to filter out the faulty touches without also filtering out real touches.

What you describe sounds like a hardware problem. I'd recommend giving the screen a wipe with a damp, soapy cloth, then a rinse with a damp cloth, then drying it. It might or might not improve matters, but it's worth a try. If that doesn't help, you probably need to replace the screen completely.

# Answer

I had the same issue, and I tried to replace the screen and digitizer and it didn't work at all (spend money for nothing).

After a few weeks, I was trying again. I touched the flex of the digitizer and it got crazy, like your picture. Then I tried to took off the board which is connected to this. When I put it again, the screen was fixed. It's been OK for many days now.

So check the board and screw it property. It is a little board where the MiniSD card reader and the reset button, also has 2 flex, one of the digitizer and the other is grey and connected to the main board.

# Question
Title: How much power does a Galaxy Tab 10.1 charger need to supply?
The Samsung Galaxy Tab 10.1 comes with a special charger which (I'm assuming) provides a higher current output than the USB standard. Without it, the device can actually die, even if the USB cord is plugged in to a USB port (albeit a little less quickly).

I'm looking for other (cheaper) AC and car adapters, but I don't know the minimum power they need to provide to power the device. Does anyone know the minimum current needed for a 5V USB connection for the Galaxy Tab 10.1, or perhaps a link that provides this information?

# Answer
This turns out to be more complicated than just the amperage rating of the power adapter.

This XDA post says that the Tablet itself may 'step down' to 0.5A charging if it cannot detect the right support in the USB host. There are some additional details in this post but I don't grok them.

That thread led me to this slashdot comment which seems very useful and knowledgeable. If I understand the story correctly, unless the tablet can negotiate with the host device, the amount of power it can draw is limited. A physical "hack" (now part of a USB standard) in the adapter can make it clear to the USB client (the tablet) that there is no host device (its a wall wart), so it can charge faster. Without the hack, the device is limited in the amperage it can use.

More details on the USB charing spec are on wikipedia.

I just verified some of this with my Samsung Galaxy Tab 10.1 and the no-name 2A USB wall charger I have. If I plug my tablet into this "unapproved" USB adapter, then I get a little red "x" on the battery charge indicator in the system tray. Additionally, I get the "media scanner running..." alert (which I think means that the Tablet thinks it might be connected to a computer). I cannot tell at what rate (2.5mA, 500mA, 2A, etc) the tablet is actually charging at, though.

If I plug the tablet into the 'approved' wall wart, I get no such red "x", nor any "media scanner" alerts.

All that said, in practice, I've found that the tablet will charge up on my no-name USB adapter. I'm not sure if that's because I tend to turn the screen off (and I don't have 3G), and thus the power draw of the sleeping tablet is less than the 500mA, or if its actually getting the full 2A.

I think the upshot is that any reputable wall charger or anything labeled as "compatible" with an iPhone or iPad will probably support the USB charging spec, and thus will fast-charge a Samsung Galaxy Tab. But I'm just guessing. It would be nice if there was an official USB logo or label for chargers that supported this mode ...
> 9 votes

# Answer
I have no idea if there's some kind of separate "minimum" spec for this, but the OEM charger is ~2A (so 4 times the USB2.0 spec's 500mA):
> 6 votes

# Answer
The Galaxy Tab 10.1 original charger provides 2A. But providing 2A is not all it takes to make your tablet happy.

In order to use the 2A, the tablet needs to recognize the charger as a charger and not a computer's USB port. The tablet is not allowed to draw more than 0.5A from a USB port. So if the tablet thinks it is connected to a real USB port, it will display a red cross on the battery and charge slowly at best.

A Samsung charger will signal it is a charger and not a data port by shorting the data lines D+ and D- and pulling these 2 lines up to ~1.2V.

A third party charger is likely to leave the data lines disconnected, so the tablet will assume it is a normal USB port and use only 0.5A, even if the charger can provide 2A or more.

I believe Apple chargers short D+ and D- but without setting a specific voltage for this line. An "Apple compatible" charger might not work.

To charge a Galaxy Tab using a non-compatible charger or any 5V source, you can reproduce the behaviour of a Samsung charger by adding the following USB adapter between the charger and the USB cable:

I tested this on a P7510. It probably works also with other Samsung devices. Note that if you use this to charge your tablet from a PC there could be a risk of frying your USB port. And of course, it blocks all data transfer.
> 2 votes

# Answer
The tablet charging current is proportional to the voltage that the power adapter can supply. If the charger has a lower than average voltage output, the tablet takes less charging current. A 6 foot USB cable can drop half a volt or more when the tablet is charging at a high rate. So, if you use a long USB cable, the tablet also drops to a lower charging current. I saw another post that said that that tablets can't charge if the voltage into them is less than 4.5V, so half a volt is a big deal.

The latest tablet charging adapters are rated at 5.3V/2.0A!!! This allows them to charge fast even with a pretty long cable with a big voltage drop (i.e. 5.3V - 0.5V is 4.8V, a lot higher than the 4.5V limit)

USB 2.0 Switches are rated to deliver only 0.5A, as are the USB sockets on most desktop computers. If you plug in your tablet to these, they will only draw 0.5A. If you're watching video, surfing or gaming, the tablets can easily draw twice this amount, which means they will be taking half their power from the battery. USB 3.0 switches might be able to supply more.

If you have a laptop, it can supply 0.5A if plugged into the wall, or only 0.1A if running on batteries.

So, if you want to charge your tablet quickly:

* Use a power adapter with a 2.0A rating, preferably with a higher than 5.0V output (warning: higher than 5.5V may damage your tablet)
* Use a short cable

I have a similar problem with the Galaxy Tab 1. It means the charger is faulty and won't charge the tablet (or will charge it very slowly - which seems to be your case). Try squiggling it around a little bit until it charge, also consider buying a new Samsung **tablet** charger (the phone charger has a lower output, which is inadequate for a tablet), don't use the knock-off brands!.

If the red X is there even when it's not charging, then the battery is faulty, take it to the service center.

# Answer

The problem is that your tablet needs to recognize your charger as a charger that can provide 2A. But only a Samsung charger will provide the right signal. Any other USB power source will limited to 0.5A. The result is that you need to get an original charger from Samsung.

Title: NullPointerException, getPhone error when trying SKD-21, Messages displaying on Samsung Galaxy s4 after update to Lollipop 5.0.1
Yesterday I updated my Samsung Galaxy s4 to Lollipop 5.0.1. It is important to note that my phone is not moded in any way nor has it been rooted. It is the standard user version phone.

After the update however, there is actually programming error messages popping up on the screen. They only appear for a few seconds at a time so I was lucky to catch a screen shot nor do they only appear when using specific apps, they seem to be at random.

Here is the error message that is displaying for me verbatim:

> Trying SDK - 21 ----- getPhone error - java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.woodslink.android.wiredheadphoner outingfix.phone.enumPhones.name()' on a null object reference

Any ideas on why this is displaying or what to do to fix it or get rid of it?

Thanks in advance!

# Answer
The error is being generated by a package named `com.woodslink.android.wiredheadphoneroutingfix`, which appears to be the package name for SoundAbout. Based on the surrounding context, it looks like there may be a bug in the app that is causing it to misbehave on Android 5.0+, at least in your case. Essentially, the Android upgrade broke SoundAbout.

You could potentially try to downgrade your device if you wanted to, but that would have larger ramifications as well. A better alternative would likely be to simply report the issue to the developer of SoundAbout. You can do this by using the email or contact us feature provided by the developer of the app. I'm sure they'd like to get it fixed, and if you provide the error message it should give them at least a decent start for their debugging.

Unfortunately, there is not much you can do to fix the error on your own (aside from the aforementioned system downgrade).

**Note: SoundAbout is no longer available on Play Store.**

# Question
Title: Android doesn't connect to proxy server
In the past I could connect to a proxy by entering the proxy's settings in the APN settings or Wireless settings.

However, now android seems to ignore my set proxy - after hitting `Save` it disconnects from 3G for a few seconds (I have no internet access), and then it connects again as usual.

To check it I also set a fake proxy (fake address/port) and it doesn't fail to connect - it just ignores my settings.

I have Android 5.0.2, so I tried to find some info about lollipop having this issue but with no luck. Maybe someone can confirm it, or has some sort of a solution?

Looks like the issue isn't related to Android itself, but to apps installed: I had ESET Smart Security (antivirus) installed with a firewall - and the firewall blocked (or ignored) my set proxy. **Disabling the firewall** solved the issue.

I'm posting it to help other people facing the same issue.

How do I find out which file system is used by my device's /system, /data and other partitions?

DiskInfo displays this information (among other things) when you select a partition to view its details. Works with the internal partitions on my Nexus 5, but should also support external SD cards and the like:

Alternatively, one can use a Terminal Emulator app which requires no usage of **adb**.

1. Download a Terminal Emulator of your choice from Play Store here.
2. Open that app and issue the command `mount`. You can also use the command `df` to ascertain the partitions to be looked in the former output.
3. An alternative for mount is `blkid` command which shows a much better output for our need.

Note:- **3.** requires **ROOT** access while the other steps can work without it.

You can use

```
adb shell mount

```

to find out which file system is used by all the partitions of your device. You need to have adb installed, of course, for this to work. You can install adb by using (Windows only)Minimal ADB and Fastboot, or you can install full android sdk, if you wish.

Title: Change color scheme on Samsung Galaxy S4 running Lollipop 5.0.1
I updated to Lollipop 5.0.1 on my Samsung Galaxy S4 this morning. Now my color scheme in apps such as the texting/messaging app is Orange, Blue, Green, and Yellow. All together. It even changes the status bar to orange while the messaging app is open. This is horrible on my eyes and just plain ugly in my opinion. I however, cannot find a way to change this color scheme at all. I have searched the phone, google, SO, etc and cannot determine how to change this scheme.

As far as I know the bootloader cannot be unlocked on the S4 so I cannot customize that way.

If it helps:

**Android Version:** 5.0.1

**Kernel Version:** 3.4.0-4408911 dpi@SWDD5005 #1

The Touchwiz Lollipop skin has a limited number of color schemes available to use that can be accessed through Developer Options. I am not entirely sure what the purpose for them really is since they merely drain away colors and mute everything. Anyway, the new way to access Developer Options is to go to the About Device under the More tab in your settings and scroll down to Build Number. Keep tapping Build Number until the Developer Options are turned on (you will see a message below where you are tapping). In the Developer Options now under the More tab, scroll way down to Simulate color space. You'll 4 options including grayscale/monochromatic.

In my opinion, these options suck. I've had my S4 for 2 years. Maybe it's time to pick up a phone from another manufacturer.

Title: No previous song button in Lollipop?
I've just updated to Android 5.0 and it has already showed that I need some time to get used to the new layouts and such. That's not really the issue though.

The thing that I couldn't wrap my head around was this:

Click for full size

It quite looks like they forgot to put in the Previous button. Is there any way I can get it back?

Thanks!

# Answer
Swipe down on the notification to expand it and you'll be able to see the previous button. It's only visible in the expanded notification, not the summary version. As far as I know, there is no way to change this.

Note, however, that this does not appear to work if you have the lockscreen set to hide "sensitive" notification information:

> \[...\] I have the lock screen notifications setting set to hide sensitive information, and thus it's locking out the full music player controls. When I swipe down, I get the unlock keypad, because Lollipop wants me to unlock my phone in order to get at the full music player. \[...\] – Derek

Left is the "before" picture, right is after swiping down on the notification:

I wanted to keep "Hide sensitive information" selected so that my texts, emails, etc. don't come through on the lockscreen, but I still want my music widget.

Here is what I did:

1. Keep the option "Hide sensitive information" selected.
2. Go to Settings \> Sound and notification \> Application notifications
3. Scroll down "Music" and select it.
4. Set "Priority" to ON.

Now I get the music widget with the pause and skip buttons and if I swipe down on it I get the full controls.

Hope that helped!

Solution to having full music controls while hiding sensitive information from emails etc on the lock screen:

Go to settings (sounds and notification) 1.Enable show all notification content 2.Directly underneath (show all notification content) select app notification (select the app you want to hide sensitive info) \- a new option has appeared (sensitivity) 3. Switch on sensitivity for all the apps you want their info hidden
