[Q] my phone keeps restarting for NO reason...help please - T-Mobile, Samsung Galaxy SIII

No matter what KITKAT firmware, MODEM, or KERNEL i use. My phone will just RANDOMLY restart out of no where. It makes no sense. The phone doesn't seem hot, I have tried countless factory resets, formatting systems, re installing GAPS, reflashing modems and kernels, and rooted firmware.
It's especially prevalant when using the GPS. Or anything CPU intensive, I would ASSUME.
Can someone tell me what the heck would be causing this?
T-Mobile Samsung Galaxy SIII

Get the Event Logger app and see if it registers any actions next time. Sounds like yet another power button gone bad though. If so im hoping the app will log the button press before it restarts.

Please, hard reboot your phone!

I believe that once you've done your first hard reboot on this phone the UI becomes permanently jumpy/choppy/laggy. Anyone?

every HTC / Samsung phone after restart, it takes them at least a good 1~2 minute to settle down

You've missed the "permanently" part.

i'll test that as soon as mine arrives next week, until then i can't verify much
No lag here after 2 reboots. One of which was pulling the battery after turning the phone off to get the serial number.

yeah, i remember you did that for the other guy, that was looking for the battery part number
By hard reboot I mean VolUp+Power. I'm not talking about powering off the phone.

that's technically a factory / ROM reset back to default
Exactly my point. It should be stutter free by default, right?

Dude, I just spent the last two days getting the phone setup the way I want it...
When we get root and I can create a nandroid backup I'll try a factory reset

Have you tried doing it again?
I have hard reset and factory reset my device at least 6 times without issue really. I had to do it the first time since I tried to port over 26000 texts it didn't seem to like that too much =)

Dude, it's different from Factory Data Reset. It doesn't erase affect your setup. Ok. How about a simple reboot - just by holding power button. Can you do that and tell me what happens?

My routine to make it relatively smooth: Power Off / Power on while holding VolUp+Power and waiting for it to vibrate a couple of times / Turn off display animations / Turn off wallpaper scrolling.

When you hard reboot it actually factory resets the data the reason its lagging cause its reinstalling all the Bloatware Tmobile put on it. So you need at least 5-7 minutes.
Ive already done a hard reset on my phone after receiving it and the reason was i had a issue with music on my sd card. I dont see the lag you speak of. If its persistent then get it replaced. I have no issues as of yet with the phone and its running great. My only slight issue is battery but that is most likely due to bloat.

Have done plenty of normal reboots via the power button (power off then power on) and pulling the battery. Mine is still quite a bit more snappy than the Vibrant it replaced.
Can somebody smash their phone for me and let me know if its damaged after? It seems all phones are damaged after they're smashed.
Seriously op, if you know it messes up the phone, why ask others to do it? Why would anybody do that anyways? Seems pointless.

I've smashed mine several times, one of which was even a sledgehammer dropped from a 3-story building right onto the glass. no damage here, it's actually less damaged than my MT4G was fresh out of the box
Sorry, just had to post the other side of things too lol

Crashing issues possible cause

I just had another crash replying to a post here using tapatalk. The keyboard had small pink corruptions as if video memory had an issue.
I pulled the battery for about 10 seconds, tried to turn it back on. No dice. I tried again except pulled the sim as well, that worked.
Maybe some of us having crashes are sim related?

I've had to do a second battery pull today. Phone locks up then about 5 seconds later the display goes dark. Not fun.

I froze twice in the past three days. I was using hand cent and browsing. The battery had to be pulled in order for restart.

Yesterday I noticed GetJar was keeping the device awake (in battery stats), but otherwise it was responsive and all good. I uninstalled GetJar and rebooted for good measure. It powered down fine, but wouldn't power back up. I had to pull the battery.
My first 'battery pull' so far!
I had my first crash today while I was replying to an SMS message. The screen produced these broken specs of green.
I couldn't exit from the SMS, eventually the screen turned itself off and then nothing.
I had to perform a battery pull to fix.
When the phone booted back up ICS complained that the launcher had crashed.
Instead of clicking 'stop' I clicked 'wait'.
Phone returned to normal after that.

Did you guys restore old apps/app data from your previous Android device? If so, factory reset and START FRESH.
I can't count the people I know that had issues all stubbornly because they refused to start fresh from a new device.

I didn't use a restore. I just added my Google account and let the phone download my apps that I more or less had from my Nexus One.
Is that OK to do?
Or should I have done something else??
Let me know, Thanks.

This is how it works. When you login all the apps install automatically.
I just noticed this morning that a bunch of apps I had uninstalled already on my GN automatically reinstalled. Odd right?

If you have "force 2d rendering" checked in the developer settings, that will cause many issues.

I don't have any dev options on. I'm basically seeing what others are. Lockup, sometimes with screen corruption, then the display eventually goes black some short amount of time afterward. Battery pull required. I thought it may be heat related at one time but it has happened when the device was relatively cool. Seems like a software driver issue that can hopefully be addressed.

Power off issue

I'm on ICS UVLE1 and it seems that I am suffering from a power off issue where the magenta T-Mobile box stays on and the phone never really shuts off. It says brightly lit and I have to force it to turn off by pressing the power button for 30 seconds. It just sucks. It happens whenever I want to reboot or power off my phone. It just never really shuts off or restarts.
I still can't seem to fix this problem and I'm just not enjoying my experience on ICS or maybe my Galaxy S2 is one of those bad apples. Sad to say, I guess my expectations were a little to high. :-/
I rooted and installed ICS mms gallery and calendar . I notice this issue you have l but it restart fine just lag on power off so I just hold power down no biggie

I was going to complain about the same.
I've even tried reinstalling, wiping, etc. Also, time zone resets to zero. F'ing annoying.
I'm looking around to see if I find anything.

have you tried formatting your sd card where the photos and downloads are kept? i had the same issue, albeit with the telus rom, and formatting the sd card worked for me.

This issue has been addressed many times. Look for dark side cache wipe. Flash it. Then you should be good to go. It has to do with using cwm to flash roms. Don't use the wipe feature in it, flash either super wipe "everything" or cache wipe from TDJ.

This is a very well known issue. If you are unrooted, do a factory reset. If you are rooted, flash TDJs cache wipe.

Also, the Dark something super wipe works wonders. Wipe, reinstall ROM, and you're ready to go.
In the Q& A forum, I posted the instructions. In the development section, you can find the Super Wipe.

I was having this exact issue during shutdown and reboots. It went away after flashing TDJ's Darkside.Cache.Wipe.
I had the same issue, just reinstall it and you'll be fine.

[Q] Phone will not remember "default" apps?

My new Note 2 will not remember default apps. For example, if I install a home screen replacement, every time I hit the home button it asks me to select which to use. Every time I click on a link it asks "Complete action using" with a list off all usable apps. Even when I select always after picking the app. It's done it on 2 different roms. I'm on Jedi-x3.1 atm.
Anybody have any suggestions? It's very annoying.
My first instinct would be to clear cache but I'm new to all this stuff so I may not even be close to right.

I'm thinking it would make more sense to ask in the rom thread if you're not running stock.

I get that on media files. Modded 7501 rom.
When these ROMs first came out the buttons were reversed. Try hitting the other button. This has been fixed, as far as I know

Probably not much use to anybody else with this problem but I've managed to make it stop by flashing a different ROM.

Random Reboots

So I have been having some random reboots and my phone has been freezing and wont turn off unless I pull the battery. I am completely stock only rooted I have never flashed a rom on this device either. I dont know what could be causing these problems the only root apps I have is super user and wifi there. Anyone have any thoughts please chim in. Thank you.
P.S. I have done 2 factory resets as well

Define "factory reset". If you have truly reset all the software, then it must be hardware, in which case, time to visit a Sprint store.
Reset through recovery wiped everything 3 times

I was using Juice Defender and this was causing my reboot and unstalled it and reflash the MA7 return to stock Rom and my problems have been solved. In my case it was software or some tweak that I did that caused my problem. My phone has not restarted ever since this has been 5 hours.
