Problem: frequent spontaneous forced reboots - Ascend Mate 7 Q&A, Help & Troubleshooting

Hi everyone,
my Mate 7 has a tendency to do unexpected, spontaneous forced reboots every now and then. I have no idea what causes it. Recently, it happened multiple times while trying to scan my phone for viruses using the Avira app. Today, I tried to launch 3C Toolbox when it happened.
Any ideas? For info, I run firmware B137SP3 and am rooted with SuperUser.

Have U already tried a device reset and a clean install of thr firmware? Monitorize it after clean install without any other app (no 3rd party apps, just stock apps). If stable, ok it' s not a matter of firmware. Then proceede by installing your apps one by one and monitorize which one of those let the phone reboot.

No, haven't tried that yet. I was afraid this might be the only way to find out what's happening. Since the reboots occur only sporadically (less than once a day), I'll postpone this for when I upgrade to Lollipop - which will require a clean system install anyway.
Thanks for the suggestion though!

How about wiping the cache?

App cache or cache partition? I have 3C Toolbox installed which automatically wipes all app caches upon reboot.

[Q] All Applications Force Closing on Reboot

I'm having this problem where sometimes after I reboot my G2x (running HellFire Phoenix V2.1 with the kernel already included) it would start back up with the "Touch Android to begin" screen as if I just did a fresh install and then nearly all my applications would start Force Closing on me.
I'm not sure what is causing this. My applications that we're previously installed all force close when I try to open it, and the Play Store is back to Market. My saved Google account is erased as well. Any ideas? It's beginning to get very annoying to have to wipe my phone and reinstall everything all over again.

have you tried actually going in and wiping /data and /cache before re-flashing the rom to see if it helps? if not, try that.
if its only happening to you on that rom, try flashing another.
if none of this works for you, then use This tool.

I always use the Nullifier application before installing the rom, yet I'm still having this weird problem. I'm going try that other wiping method and see how it goes. Thank you !
Downloads of gapps/ROM might be at fault also. If wiping doesn't solve it for you then you should re-download them.

[Q] Why does it take life-long time to uninstall app?

Hi, Guys,
I'm using P5110, with CM 9.
Everything was fine at the beginning, but din't know since when, it takes forever to uninstall any app, taking more than 10 minutes in many cases.
Sometimes, rebooting the tab would help to get the app uninstalled, but it is ridiculous to do so every time before uninstalling apps.
Any idea how to solve this?
Thanks!

Hello there, even though i don't your same tablet i may be able to help. What rom are you currently on, and are you rooted?

Hi, Jxt,
Thanks for your attention.
The rom I am on is: [4.0.4] CyanogenMod 9, downloaded from:
http://forum.xda-developers.com/showthread.php?t=1722099
Yes, my tab is rooted.
Hope it won't require complete system re-flashing rom, 'cause when thinking of flashing rom and installing, setting all the apps, it drives me mad.

Hello, your welcome i was just wonder, did you restore apps with titanium backups?
Are you running out of space?
Try going into recovery and wiping cache? NOT Factory !!

I've just wiped cache, but sorry it doesn't work, problem remains.
Anything else to try?
P.S.
I've installed FREE MY APPS before, and therefore, have install/uninstall many apps on this tab, but months ago, I've stopping doing this and removed all the staff, including FREE MY APPS.
Maybe during that period, some mess was done to the system?

The only thing i would say to try now is flashing a different rom, i recommend Pacman roms.

I assume you are trying to uninstall from your Setting/Apps.
What happens if you log into the Playstore App and try to uninstall apps from there?

Have you tried to go into recovery and clear cache?

Problem finaly solved wihout having to reflash rom, or even switch rom!
All credit goes to a miracle app: SDmaid !
After trying wiping cache, and using several apps to clean the trash files (some tools did clean hundred MB of trash files) without any help, I tried SDmaid.
It further cleaned out tons of trash files, and right after that, it takes only few seconds to uninstall apps, work like charm!

[Q] Play Store crashes when updating multiple apps

Hi, I have a Nexus 5, completely stock 4.4.2, never tampered
Whenever there are multiple updates in the Play Store and I press "Update", the first app updates, then the second one starts downloading,
but the download hangs at some point, then after a few seconds the entire Play Store app closes without any message.
After that I can open the Play Store again and try to update the apps, but they only update one at a time, because on the second update it always crashes.
All the Google apps are at the latest versions, Play Store has version 4.6.17. This is happening for a while now, but I can't pinpoint it to a certain version of the Play Store app, but in the past I did not have this problem.
I've tried restarting the device, clearing data and cache for the Play Store app, clearing the cached data for the entire system, even switching the runtime (btw the problem is happening on both Dalvik and ART), but nothing helped. I also have enough Available space: 4 GB as reported in Settings/Storage.
On my wife's Nexus 4, also completely stock and with updated Google apps, the problem it's not happening, so it's not something in my environment.
Did anyone else have this problem? I searched the forums but found nothing relevant.
Any advice?
Thank you.
Hello,
Clear Playstore's app data and cache and reconnect your google account as see whether the problem persists?
Already did that, I said in my post, did not help.
Can anyone provide any advice? Thanks.

Hi
I have the exact same problem on my galaxy note 3 so nothing to add except that I tried a little trick that allows it to finish the updates without having to restart the store. I close it immediately after the batch download starts and then it continues updating in the background. it works most of the times but not always. I really wish someone had a solution to this problem.

Did you by any chance ever went into the recovery and tried clearing the cache from there?

Yes, I cleared cache and Dalvik from custom recovery. I did a lot of searching on google and XDA and I followed all the guides, including uninstalling play store updates, clear data and cache from apps manager for play store and also Google services framework and download manager but no improvement
Im in the same boat as you on this one.

Are you rooted? What custom recovery are you using? I myself am all stock, never rooted or anything.
And how long does it take to clear the cache from recovery? On my Nexus 5 with stock recovery it takes very long, around 5 or 10 minutes the first time I do it in succession, but it finishes succesfully. If I repeat the clearing of cache without rebooting then it takes a few seconds, like normal.
I read somewhere that it might be an issue with errors on the cache partition and that reformatting this partition might solve it, but I cannot do it from the stock recovery. Maybe if you have the option of reformatting the /cache partition in your custom recovery you should try it.
Another thing that you can do is try to catch the errors with logcat, if you have root you can use an app, I used adb to save a logcat and found some error messages related to the installing of apps but could not find how to solve them. I will post the logcat later.
If you can get a logcat maybe you can post it and we will compare the errors.

Yes I am rooted using CWM Based Recovery 6.0.4.7 with SuperSU 1.94 and BusyBox 1.22.1-Stericson on stock Samsung firmware Android 4.4.2 NB4 unbranded
clearing the cache from CWM recovery only takes a few seconds in my case. I did not try reformatting or anything else because I don't want to risk bricking it.
I will post a logcat as soon as I know how to do it.
Yup to both. Wipe was very fast... Almost too fast in my opinion

Has anyone found the solution yet? no way to update all apps at once. this is driving me crazy especially when there are many apps to update
I'm also experiencing this behavior as well.

I have the same issue. Stock rooted...
I don't have a nexus but I was using a google edition ported ROM for my HTC One and was having the same issue drive me nuts. I flashed the stock sense ROM back and the store works fine now. It seems like this problem is google edition devices/OS. I never found a fix though, except to enable automatic updating so it happens in the background. That worked for me
indeed the updates work fine in the background but I would really like to know what causes this issue
Those having this problem can you guys make sure you have the latest Google Play build? Latest is 4.8.20. Go to your play store, go to play store settings and at the bottom it should say 4.8.20. If your version is earlier than that, tap the build version and it should say there's a newer version and that it's installing. At that point, exit from the play store app, and give it a minute or two. Enter back into the play store app, and you repeat the steps to see that you have upgraded your play store build.

Yes, the Play Store app is updated to the latest version. Now I already got the 4.4.3 update, but the issue is still appearing, but not everytime. I think it depends on the sizes of the updating apps, it might be something related to the cache partition. Can you guys try and clear the cache from the recovery and see how much it lasts? For me it lasts more than 5 minutes and it doesn't seem normal.

I had the same issue on my S4. After the play store closed about 5 times today when updating apps I decided to Google it. I found someone with a similar issue, and their fix was to enable the Download Manager app, that had somehow been disabled. Mine was already enabled, but I cleared the cache from that app, and then I was able to update my remaining 5 or so apps with no crashes.
I'm not sure how permanent of a fix it is, but it's working so far. Don't know if I'll have to clear it again later or not.

[Q] TWRP broke app installation

Everytime I wipe cache and Dalvik cache, after reboot, the android is upgrading progress is almost immediate, then I get "Unfortunately, Update Device has stopped".
So I restored a backup from a week ago. Now, none of my play store apps will update. Tried to install a new app still no luck. Tried installing an apk also no luck.
Any suggestions?

Unless using greenify is considered as freezing, no. It should work fine.

[Q] Soft reboots after installing apps

Every time I install or update an app, my phone (running 5.0 aosp lollipop with xposed) tends to soft reboot, it doesn't always happen and it doesn't always happen just when installing an app (sometimes it just does it while watching a video for instance) but it's driving me crazy. I think this could be because of the memory leak (so that my phone reboots because of a lack of RAM), but maybe it's just an app causing the trouble. Could someone please take a look at it for me? I attached two logcats. Thanks in advance!
here they are

With random reboots, first place to look is kernel, then Xposed, then ROM.
If you are running stock, remove Xposed.
Wiping cache and dalvic cache solved the problem!
Now I know what to do when it reoccurs
