[Q] AT&T GS3 Freezing and Rebooting after Stock JB Update / Rooting (LONG)

Help! My phone is freezing / locking up and rebooting several times a day now!
I successfully did the stock AT&T Jellybean update this week when it became available via Kies.
I had no issues with the initial upgrade…it seemed to go smooth.
After a day…or a few hours….I can’t remember…I did start noticing a few issues with Touch Wiz closing or freezing and some other apps misbehaving. I can’t even remember what exactly the issues were.
I was also having some other quirky issues with the phone on stock ICS before the JB update…so I have been meaning to do a factory reset and reinstall everything.
So with the phone being even more flakey with JB I went ahead and did a factory reset with my new JB setup.
After a few hours setting up the phone with all my apps, settings, etc I noticed two issues. Swiftkey would not remain selected as my default keyboard and AT&T Voicemail viewer would not retain any of my account settings after a reboot.
After some Googling I learned that this is a know issue with JB 4.1.1 for many apps…they don’t quite install properly and something happens during shutdown that causes the settings to be lost. The only work around seemed to be:
Root Phone
Install apps
Backup with Titanium or other backup program
Uninstall apps
Restore apps – then they somehow install properly and work
I did this…first time rooting the phone….and the root and work around worked perfectly first time.
But after continuing to install apps and tweak my phone the real problems have now begun.
The phone is completely freezing at random times…in any app or in the TW launcher. It seems to just sit there frozen until I hold down the power key long enough to force a reboot or take out the battery.
There are no force closes or other error messages and I have found no other pattern to the freezes.
So now the phone is almost totally useless. It may work for a few hours…or just a few minutes before locking up. Worse…I have no way to know this has happened if the phone is in my pocket.
I did another full factory reset using the Recovery Mode and reinstalled everything again and am having the same issues.
I fear the root somehow corrupted my phone or one of my apps is totally incompatible with JB but I have to many (~70) it will be very hard to tell which one.
The other issue I am having is the battery is draining in just 4-5 hours even with light use.
Coincidentally….4G LTE was just turned on in my area this week so that would be a factor in both the battery drain and maybe even the lockups. I have a Microcell at home…wondering if 4G LTE and my Microcell are not behaving.
There are just too many variables with a new ROM (JB), fresh rooting of the phone plus recovery app installed, plus 70+ apps, plus new 4G LTE, plus my Microcell.
I don’t know what to try next to get the phone stable or to get the battery use reasonable.
Please post any and all suggestions….
One thing I’d like to clear up or eliminate is the root issue…is there any way that is the cause of my phone’s current problems?
What a mess of a week! Instead of the total awesomeness of JB, 4G LTE, and the fresh experience of using a rooted phone...all happening for me in the same week...I get a total headache and useless phone. Sure hope I can dig my way out of this.
Thanks for reading my long post!

I'd say to flash stock rooted official jellybean from here http://forum.xda-developers.com/showthread.php?t=1968625 i'd then do a Hard Factory reset *2767*3855# then you can install apps that are compatible with jb but not the app data and see how the phone is. also, for signal issues, try using a different modem located herehttp://forum.xda-developers.com/showthread.php?t=1831898

Thanks for the ideas....had not heard of the "Hard Factory reset *2767*3855#"....how is that different from a factory restet initiated from winthing Android or from the recovery program?
Also - is there any quick / easy way to know which of my apps are supposed to be compatible with JB?
Sure will be a pain to reconfigure everything again.
Should I be safe installing my apps via Titanium backup restores? (as long as I don't restore data)
Also - what about restoring my IMs and call logs from Kies? Is that safe?

Do you happen to have juice defender? I had the same problem, and noticed it only happened when I was on battery. I uninstalled that and it stopped rebooting.

Nope....juice defender...
And my phone doesn't really seem to be rebooting....just freezing up. I have to force it to reboot by holding down the power button for 10 seconds.
About to try a fresh factory ROM install (pre-rooted) and a hard factory reset.
Then I'll add my apps back very slowly to see....
What a pain in the you know what!

Well...I did all that...and no luck. Still freezing up.
I could not actually do the exact *2767*3855# reset...the phone would not respond to that command. So I used CWM to format the SDCard and also did a factory reset there.
Reinstalled my apps carefully and without data restore...boom....phone is locking up all the time again after maybe 12 hours of good operation.
Either this build of JB is not working on my phone or it somehow got fubar'ed during that first upgrade.
My plan now is to restore to factory ICS un-rooted....reset the flash counter if possible....and return the phone under warranty if possible.
Any recommendations for this?

Got replacement phone - still freezing up!

HELP!!!! Please!!!!!
I did a warranty RMA and got a new (refurbed) phone from AT&T. I set it up with stock ICS and it seemed to work fine. I installed CWM without rooting via ODIN and did a Nandroid backup. I then used CWM to load TWRP recovery and did a backup with that.
Then I loaded the stock JB room with root. Tweaked the phone and app settings a little and things seemed to be fine for 1/2 a day. I reinstalled TWRP since the ROM flash replaced it with stock recovery. Things still seemed fine.
So...with JB rooted and seeming to work fine....I booted into Recovery (TWRP) and did a fresh Nandroid backup since the phone was finally all configured and working (apparently).
Well after rebooting from the backup...the phone is acting all crazy again. It seemed to crash my home WiFi network....had to reboot my router. Now the phone freezes or locks up any time I disable WiFi or change WiFi settings.
I am just cursed with the GS3!
Two separate phones with stock AT&T JB with root...one running CWM Touch and the new one running TWRP and both lock up or freeze all the time.
Should I give up and try custom ROMs? Give up on rooting?
I want TouchWiz for SBeam and some of the Samsung apps that I like better than stock...would rather just stay stock with Root.
What can I do to get this phone stabilized with root and JB???

Just did another test...
If I leave my house and walk a couple hundred yards away...as soon as the phone finally loses the WiFi signal and disconnects it locks up.
Seems like all my issues (with first phone maybe too) are tied to WiFi.
Is no one else having WiFi issues with JB? Could it be tied to rooting somehow? For instance...maybe the stock rooted ROM has different modem or WiFi drivers...or different kernel than the actual stock JB ROM I first used via Kies update?

I've got the KIES JB Update, & rooted. I am not experiencing any of the issues your having. It might be helpful if you could post a list of apps & widgets that you have installed, If you have frozen or removed stock files.
It sounds like you may be experiencing some app conflict issues.

I have not frozen any apps or done anything I would consider advanced or risky....
I tried running with what I thought would be just "safe" apps....no luck. I've got most all of my apps installed and did a Titanium Backup so here is a dump of all the user apps backed up:

Having the exact same problems as you. Please help. I'm also considering giving the phone back at Best Buy and having them give me a new one with ICS and leaving ICS on there. My steps are very simple. I had the stock ICS ROM from AT&T and I used Kies to upgrade to stock JB. That's it, nothing else, no rooting, nothing.
I am seeing exactly the same behavior, when wifi switches to 4G or even sometimes when bluetooth comes on, etc I will see the lockup and hang. Have to hold down power button to restart. But I don't think this is completely the issue, because even if I turn off wifi, bluetooth and only leave on 4G, then I still will see random reboots, but a lot lot less frequent. Also, I have always had 4G and I see the battery only lasting 4-6 hrs, so I think this is normal with 4G. I saw this even with ICS.
I have not done any factory reset or anything - I would assume if you use the Kies s/w to update and it leaves your files and apps on there, then it should just work. But I will try the factory reset once I backup my contacts, etc.
I'm a little shocked that people are having this problem with a newly released ROM.

After several re-flashes to stock JB with root and still more freezing with WiFi, etc....I gave up and loaded a custom ROM this morning.
I'm running BlackJelly...and after about 8 hours it seems be be running great so far. It is TW JB-based...and having very few issues with it. Battery is poor but it takes a few days of charging and use I guess to get the battery / phone / ROM calibrated. AT&T Visual Voicemail is not working and the phone shows H instead of 4G LTE...but I'm sure I can fix those issues by searching through the hundreds of thread pages on that ROM is this forum.
Give it a try before you switch to ICS or trade in the phone. You can always flash back to stock un-rooted and use Triangle Away to reset flash counter.
Good luck!

Still stuck with crashing phone!

Well...after over a week of trying it out....BlackJelly did not help me. Still had freezes / lock-ups.
I can't tell if the phone is re-booting itself or just re-launching the Launcher (I us Nova but tried stock and Apex too). The phone appears to re-boot on it's own but the up-time under status would not reset...making it seem like not a re-boot but a launcher reload or something. Pretty much same issues as with stock JB.
So I gave up and tried CM10.1 nightlies....and wow....crashing all the time now. Whereas stock JB and BlackJelly seemed to crash when I left my home or left any WiFi network or even just when I disabled WiFi while connected....CM10.1 crashes all the time while at home seemingly at random. I can get 5 hours of great use...then have it crash 5 times in an hour. Seems to crash a lot in the settings menus.
This is with my second (replacement) phone. I am just cursed!
How do I effectively use a LogCat app or something to find out what apps or services or whatever are crashing my phone? Help!

Read through this whole thread and no where did you ever mention clearing your cache. Clear your system cache/davlik cache and reboot.

Sorry...should have mentioned that. I've cleared the system and davlik cache many times...before and after flashing. I've done full system wipes / resets, formatted my SD card...everything I can think of.
I either have a rouge app that I seem to install right away after clean flashes....or a rouge Wifi router in my house that messes up my phone even when I leave and use other networks...or a rouge ATT&T microcell that does the same....or a rogue LTE area in West Michigan....
Or a second bad phone sent from AT&T. But no form of JB seems to work for me no matter what. Guess I could run a clean install with no apps for several days...and then add in an app a day for the next 2+ months until I find the bad app...if that is even the case.
So bummed with this mess!

Interesting....that might be what I was experiencing....but I never thought that was it....did not notice that cause/effect.
I gave up and went back to stock / rooted ICS / TW...version LH9. Loaded it yesterday and have had 24 hours of great use...no issues.
I miss JB and Google Now...but at least my phone works!

I'm not sure for stock JB but on other ROMs, you could try changing your governor and scheduler.

When on CM10.1 I tried bumping the minimum CPU speed to 484 and 5xx (can't remember the actual numbers)....and the maximum CPU speed to to 14xx and 13xx (again, can't remember)....and this did not help.
Not sure if that is what you meant tho.
Anyway...I gave up and went back to rooted stock ICS (LH9) and the phone is working great. I've given up on JB for now. I will wait for a new major JB release from Samsung before I try again.

Q: The phone keeps freezing when I go into landscape mode.
A: This has been covered many times in the thread, but to reiterate: If you are using the AOSP lockscreen you must disable "Ripple Effect" in Settings -> Lock Screen -> Lock Screen Options

[Q] Question RE Random Reboots and Freezing on stock 4.4.2

I have read around regarding this problem without luck, and hope that someone can advise if I have missed anything.
I used to use this phone and as I liked to tweak it was running a custom rom (think it was Wanams). Anyway I got an upgrade ages ago, and my wife carried on using the phone for a while. As she just needs a standard rom I recently decided to factory reset and use Odin to flash the newest stock rom (N7100XXUFNE1 - UK). This is when the problems started. Initially the Wifi wouldn't come on, but after factory resetting and using the Samsung Updater in Kies I finally managed to get Wifi back. Then, while setting it up and installing apps from the Play store it started freezing and had to be rebooted every 5 or 10 mins. Finally after doing this a couple of times, all the apps were installed and after leaving it to "settle" it seemed to be better. Now however, 2 or 3 times a day, when playing games or using other apps, it will just reboot.
What I have tried is:
* I have tried clearing cache through the stock recovery
* Tried a number of Factory Resets
* After reading about the SDS problem I have tried running the "dummy file generator" to fill the internal memory and this completes ok. I guess this means that although I have memory that is/was susceptible I applied the original SDS fix early enough with the custom rom that all the memory is still ok?
As I have the newest bootloader I can't downgrade that, but as I don't care about triggering Knox I was thinking of rooting and installing a custom rom to see if any of the other Kernels help?
Has anyone got any idea's what could be causing this and what I can do to fix it?
Thanks.

[Q] S3 Turning Off on its Own

I've been regularly running cyanogenmod 11 on my Bell S3 without many issues. Last going off, I believe I was running either M11 or M12 of CM11, and all was well. Then, curiosity got the best of me, and I slapped on CyanideL Lollipop beta, and while that ran pretty damn well for me for about a month, I reverted back to CM11 a few days ago due to some minor bugs and annoyances (mostly camera). Anyways, since reverting back to CM11 M12, my phone has been randomly shutting off, not rebooting, just off. It has happened while it's in my pocket not really in use, or it can happen while I'm going to check my text messages.
Thinking this was an issue maybe with M12, I updated to the latest nightly, but nope, its still the same. Some of the times that its happened in my hands, I've seen the Power Button menu pop up, and then disappear. A few seconds later, boom, off she goes. It always powers up again when I power it back on, but I would like to try to get to the bottom of what is causing this, as it is being very annoying for me.
The question is, what can I do to try and nail down this issue? When flashing back to CM11, I did the full wipe, then dalvik/cache after the flash. Is there something that happens when you go from 5.0 back to 4.4 that may cause this?

This is possibly related. I tried out an unofficial cyanogemmod 12 rom on my AT&T S3 for a while, but decided to revert due to camera not working. So I installed S3Rx ROM on the phone and had some issues. The phone would get stuck on the loading screen and never get past that. I did the standard data/factory reset, cache wipe and dalvik wipe before installing S3Rx back, but no luck. The only way I could get it to install correctly was by formatting /system, /cache, /data and /data/media in ClockworkMod recovery. But be aware that you will lose all personal data when you do that so be sure to backup.

Alright, I'll backup what I need to, and do a full wipe as you suggested. I'm pretty sure I did that when I downgraded to begin with, but no hurt in trying it again.

You could flash back to completely stock 4.4.2 using firmware from sammobile.com, depending on the bootloader on your phone.

If I do go back to Stock 4.4.2, would I be able to re-root again? Its been a couple of years since I had to mess with stock, so I don't know what has changed.
I've tried a few different things here, completely wiping everything, installing a 4.4.4 kernel, installing CM11 from scratch, restoring from TWRP, etc etc. Still having the issue.
Last thing I'll try before going to stock is to try going back to lollipop.
Update: I'm starting to think that this is just a coincidental hardware issue. It seems to have something to do with my power button, perhaps there's something stuck in it that's cause the button to be pressed. Right before it shuts off, the power menu pops up for a split second once or twice, then the phone becomes unresponsive for a second, then its off. Certainly sounds hardware related. Just attempted lollipop again, and same result.

I think you are correct in your assessment. Open up the phone and see if you can find anything that looks odd.

Note 3 keeps on black screening/freezing/random reboots

Hi everyone. I have a sporadic problem with my vanilla note 3 from t mobile. Its a totally random occurrence but sometimes it will freeze(loose all input functionality) sometimes it will just stay black screen(no input taking) and usually (not always) it will reboot itself after this happens(sometimes a battery pull is required). Is this a memory leak issue? Thanks for any help. Sometimes it will run fine for a week or 2 and then all the sudden it will start acting up.

Was it rooted? I had a similar issue before mine was rooted, some of the system load programs that I didn't use would start up and then grab all resources. ..

Mine was doing the same thing while rooted with towelroot. Even after I unrooted it was doing the same thing. I didn't try a factory reset, but T-Mobile is sending me a replacement phone.

If it was my phone I would do cache wipe first, if still no go then full factory reset and I would then reinstall most important programs first.
Restarting phone every few days is not a bad idea on it's own and BTW when was the last time you cleaned garbage from it?

S9 Randomly Rebooting while Idle

Hello everyone.
I'm currently with an annoying issue:
My Samsung Galaxy S9 (non-rooted) is randomly rebooting only while idle.
Whenever I'm charging, playing or perform any interactive activity, the phone works as it has been working for the past 2 years.
As soon as I left it idle for a while, it simply reboots. Usually do not take more than an hour for the reboot to happen.
Already performed a facory reset, cleared cache, force shutdown (power + volume down), worked on safe mode and nothing seems to lead me to the root cause.
It started on tuesday (December 29th @2020).
Thanks in advance,
Caio

I have had a similar problem for a long time. Sometimes my Galaxy has given to restart without stopping as far as it wants ... Once it happened to me that for a day it did not stop restarting after installing the Google assistant, only by entering safe mode and deleting it I could solve it .. . And one of the last was that I changed the CSC and the mobile just did not stop restarting, even after downloading and reloading it, I deleted and formatted absolutely everything and I could not use the mobile normally ... After several tests I realized that it restarted after unlocking, so I deactivated the passwords and fingerprint but it did not work, so it occurred to me to install another launcher and problem solved. I have no idea why this is happening to me, maybe is an error in the internal memory due to a bug in the firmware (?)... Anyway, I had read some time ago that there were similar problems caused by a GPU failure in the Snapdragon models, but I no idea.

I already use Nova Launcher, so I dont think this will fix my problem. Now its taking more time between rebooting cycles buts its still there.
I guess my last attempt will be to flash a stock ROM and see if it works.

reflash firmware via Odin. gert FW(firmware) from sammobile.com/firmware and use SamFirm to download, as it downloads 4x faster than from thr site directly. When flashing, use the HOME_CSC vs just the CSC file, as the csc factory resets whereas home_csc keeps your files and settings etc etc. If that doesnt fix it, you have a hardware issue(IMO, at least, and ive been rooting samsungs for a decade). If you have a hardware issue, id get it as good as i could and use the trade-in specials sammy has going
