Debugging a phone ? (xperia mini) - General Questions and Answers

My phone has a weird bug – after it goes out of 3G/data range for approx 15-20 minutes, the homescreen starts flashing and the phones starts vibrating continuously. Sometimes I can turn off the screen and the flashing/vibrating goes away after about 5 minutes. Otherwise I have to take the battery out to reboot.
The phone has worked no probs for a year, then started doing this a couple of months ago. I would really appreciate any tips on how I narrow down the cause of the problem.
The phone is a rooted 2011 Xperia mini, running Sony GB, and the problem happens on both ADW launcher and the stock launcher. Here's what I've done so far;
- uninstalled facebook, turned off spotify sync
- turned off all syncing apps except gmail.
- turned off all the apps that needed root or that run with a notification icon that I've installed since having the problem
- read the play store reviews for my other existing apps to see if they are causing a problem.
So, short of uninstalling all my apps and adding them back one by one, I'm not sure what to do next. Any ideas?

[Q] Thunderbolt Slowdowns

Greetings,
I have an unrooted Thunderbolt running launcher pro. When I exit applications, often there is a significant delay in loading up the home screens. Sometimes it happens so often that the device becomes paralyzed for 15 or more seconds before my home screen along with apps pop in.
What are the reasons for this? I have tons of apps, many of which have not been moved to the SD card.
I have tried going back to sense, but the problem persists making me think it isn't a launcher related issue.
Thoughts?
so i get a better picture of whats happening
1. when you first installed launcher pro did it have this lag or did it happen latter.
2. by going back to sense do you mean uninstalling all of launcher pro.
3.- strange question i know but - have you completely powered off the device recently, by that i mean power off like normal and pull the battery then just let it sit for like 10 minuets.
Thanks for your prompt reply.
The problem persists even after taking battery out and restarting.
I did not uninstall launcherpro, I just switched temporarily back to sense to see if I could replicate the problem, and I did.
The problem seems to be getting worse as time goes on, the reason I think it may have to do with adding all of these free apps of the day from amazon.
When I initially installed launcher pro, I never had the problem.
I also seem to be having random reboots several times a day.

i think whats happening is your RAM running low on memory, sense uses a lot of RAM like 300+ Megs and you can't stop it unless you root.(not trying to peer pressure you or anything). but for the time being i suggest to go into settings/apps/running and see if you have apps running in the background that take a lot of memory space. and force stop the ones you don't use that often.
and as for the reboots could you check the baseband version in the about phone part of settings?

[Q] My transformer keeps restarting...

Hi,
Today my transformer (B6O serial, Andriod 3.2) started having a pretty strange behavior: when left in standby, time to time impredictively reboots, or better, display switches-on showing the start screen (the one with the Nvidia logo) without really rebooting. The only way to go on is pressing the power button few seconds to force the reboot.
Any idea about what's happening?
It looks like something turning in background is causing the problem: I tried uninstalling applications installed the last week, but problem is still there.
When on, tablet is pretty stable, so it does not look being a hw problem...
I'll go with a full reset only on extreme ratio: if being caused by third party sw, it will reappear as soon as apps are reinstalled by market with my google account.
Thanks in advance for any help
If this is not rooted then definitely try a factory reset as it could be a hardware fault as well and might have to get it fixed.
If you find an app that caused it let us know
This happens to mine.
My transformer will just keep rebooting itself in a loop, what causes it is the wifi. The router that it tries to connect to must screw up after being continuously on, so I just reset my router and it works again
(also disabling wifi on your transformer will stop it from rebooting, a good way to check if this is what is causing it)
Well, night passed with no reboots.
To note:
- I have left it in stand-by with a minimum of applications open (advanced task manager, navigator, email, maps, accuweather, antivirus) and associated services
- my home wifi swithches off during the night (but ayway was on few hours, and no reboot)
My transformer is not rooted, and I donot understand why it should reboot...
I' m now thinking the culprit could be a game (it always happened after my children played with some games). I have now to check whether I am right and which is the game causing the problem (is it the game, the graphic driver, or the hw?)
Of course, I'll keep this post updated.
culprit found
Finally I found the culprit: it is the hardwood games extracted from a Toshiba device ( http://forum.xda-developers.com/showthread.php?t=1204691).
Games work with no trouble, but if left open putting the transformer in stand-by time to time makes the os crashing... (no problems if quitting/killing the application).
Just removed from main screen and no longer accessed, and transformer stopped with random reboots.

Stock ROM: crash / reboot every 9 days 9 hrs 30 min

My stock ROM crashes (or auto-reboots) every 9 days 9 hrs 30min like a clock.
It happened for at least third time in a row, or most likely it is going on like this all the time because I only noticed this odd behavior when I installed a little "uptime" app. After 3 times obviously that's not coincidence, something is causing my phone to crash or reboot every 9d 9hrs 30min.
Has anyone else notice or had same problem?
Stock rom, locked/unrooted, with stock apps and very few extra apps installed, after previous crash I removed almost everything I had installed in the past, I kept only AirDroid, ColReader, Google Drive, File Manager, Mobo player, Skype, SPB TV, TeamViewer - nothing else, yet it still crashed. I can't figure out is it ROM or any of the apps.
edit - perhaps I should have posted in ROM development... Moderator, please move it?
I wish I could help but I've never been able to stay on the stock ROM for that long.
But....no, you've posted in the right place. Put it in developement and it'll get moved to HERE.
There's a TMobile app on there that monitors the days until suggested reboot (7 days) and will then proceed to "warn" you consistently when you're over that period. It is possible that this app is clashing with one of your other apps or doing something in the phone - maybe using too much memory? /shrug
My phone does the exact same thing after a week but it doesn't reboot, it just randomly "soft-crashes" after I hit the back or home key while playing a game or backing out of dialer, apps, etc.
It's extremely annoying and happens whether I have few apps or my normal stock of apps; the only time it doesn't happen at all is after a factory reset (if I don't update anything).
The only thing I can do to stop it is to reboot the phone, as suggested on the 7th day...as soon as I see that notification, I reboot and so far so good.
Good Luck.

Nexus 5 dead?

Forenote, my N5 was running PSX v2 and Franco Kernel r13 flawlessly for weeks when this ramdomly happened.
Used my phone today just as I have for weeks on end with little to no issue until around 8 or 9 hours into my day the phone started to lag very badly. Redraws, stutter, unresponsiveness, you name it. I was surprised as this phone usually flies! So I cleared my recent apps and that seemed to help slightly, but it still was very slow. I used cache cleaner's built in ram cleaner to stop all running processes (which I never do) and it seemed like the issue was fixed. The system UI and launcher redrew and I was good to go.
Until I started to play some music in Play Music, a pop up constantly popped up that YouTube has stopped working. I didn't even use YouTube today! I tried to then open the YouTube app and it wouldn't open whatsoever. No animation no execution, just a dialog box reading, "Unfortunately, YouTube has stopped working." I went into app settings and cleared cache/data/and force stopped and the app still was misbehaving. I reinstalled the app via the play store and it still wouldn't open. The dialog box wouldn't stop popping up this whole time mind you.
I was thinking what the hell is wrong with my phone today!? Maybe a reboot would fix things. I tried rebooting and my phone got stuck at boot animation. I force shut off and rebooted into recovery, formatted cache and dalvik cache and rebooted. This time the boot animation actually froze.. I was like what the f***! I let it sit for a few minutes to see if anything would happen without any luck.
I force shut off again and now the phone won't even turn on. Not into bootloader, not normally, the thing won't even charge! So here I am with a dead phone and a $450 paperweight. I'm just so lost I have no idea what could've caused this really unusual sequence of events.
Any ideas? Thanks in advance.
A bad phone. Rma it
Was the phone hot when the weird things happened?

Nothing seemed out of the ordinary temperature wise.. Although my phone has overheated and shut off before that was maybe 2-3 weeks ago..

[Q] Phone suddenly having software issues

I've had my Z3 for about two weeks now, and all of a sudden last night I noticed it constantly restarting itself (at least once every few minutes). Along with this, it no longer showed that I had anything in the Album or Walkman apps, and several home screen widgets were blank. A lot of other apps won't open, and there's a lot of lag overall. I tried connecting it to my computer, but the software said --it just restarted again while typing this -- that it could not connect. I noticed a couple of days ago that the screen showed nothing but static for a second, an issue I've seen around these forums but brushed off since it only happened once. Has anyone else had this happen? What do I do? My phone is basically unusable at the moment and I intend to keep the power off to keep it from constantly restarting. Thanks for your help.
Factory reset it if it still has issues, then exchange it.
