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
I went through from 4.1.1 to 4.1.2, no problems, phone ran fine after update. Then went to 4.3, same thing. The phone was running fine so I booted back into recovery and removed Knox as well as manually rerooted by flashing SuperSU. Rebooted after that and still no problems, phone was running great. I then make a backup so I have a restore point of stock 4.3, rooted, and without Knox. I then go on and try to flash Dandroid and get a status 7 error and the phone was acting up after I rebooted.
At this point I go back to my backup and simply restore it and reboot again. The phone boots up, so that's a good thing. The problem is the GApps will not run and it continuously has a pop-up notification. The phone is rendered unusable like this. I got lucky once and was able to try and launch ROM Manager to see if fixing permissions would work, but it also closed. I tried flashing a 4.3 GApps package with no success and even tried reflashing the 4.3 update but got a status 6 error.
I'm at a loss here, does anyone have any ideas on this?
Not sure if this will help much, but even when plugged in via USB my computer will not recognize the device. The S3 states that it is connected and it does show up in Device Manager, it just won't show up as any kind of readable memory.
Trying to ADB sideload a rooted stock 4.3 ROM now. Any advice at all would be a help.
EDIT: I took a video (https://www.youtube.com/watch?v=tJ-eaQ_9mVI) of the problem so everyone can see what I'm talking about and I also found a fix.
I'm not sure what was causing it, but after a solid day of researching it online the closest thing I got was resetting app preferences and also trying to clear any data of Google apps. This seemed to sometimes slow the popups down for me or create a longer gap before they just came right back in full force. So, going off that small success I had managed to navigate my way over to Settings -> Accounts -> Backup and reset -> Factory data reset and ran that. The first boot after that took a very long time, I'd say a solid twenty minutes but it did work. No more error and everything has been going smooth for me since. A restore of apps with Titanium Backup also did not bring the problem back up again, so the device seems to be good as new again.
I apologize if any of these is out of line, I just thought I would follow up with a solution in case anyone else has this problem and can't seem to fix it. Maybe this will help them.
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.
I have been having issues with my Note3 ever since the kit kat update back in April. It worked flawlessly on Jelly Bean and I had no issues for over 3 months. I updated to kit kat via Kies with everything completely stock. Since then I get completely random reboots, it could happen when launching an app or even unlocking the screen, and it happens 2 or 3 times a day. So far I have tried 2 factory resets, clearing dalvik cache, and replacing the battery with an Anker replacement. I have tried turning off auto-updating of apps, and turning off wifi scanning. I have also tried running the phone with no apps installed. So far nothing has worked.
I have read several posts with people blaming the stock kernal for these reboots, but there is no definitive solution to this problem. I am looking for any and all help the community has to offer.
Some additional info:
Running latest stock rom- rooted via effortless method
Stock Recovery
Knox is still 0x0
No sd card in phone
Since you have no issues doing a factory reset, I recommend the following:
1.). Backup all the data you need
2.) Download the newest carrier available firmware for you from sammobile.com
3.) Flash via Odin
4.) Once finished and phone has rebooted, return to stock recovery and perform another data wipe
That will 100% fix your issues, sounds like maybe a corrupt system partition or libs

Since you have no issues doing a factory reset, I recommend the following:
1.). Backup all the data you need
2.) Download the newest carrier available firmware for you from sammobile.com
3.) Flash via Odin
4.) Once finished and phone has rebooted, return to stock recovery and perform another data wipe

Thanks, I'll give this a try. Last night I uninstalled a bunch of bloat ware with titanium backup to make sure it's still not an app issue. If it reboots again I'll reflash the firmware. Since I'll. Be flashing stock it shouldn't trip knox right?
No, latest firmware complete stock will not trip Knox, as long as you're either doing a parallel upgrade NF9 > NF9 or NB4 > NF9. A downgrade will either fail or trip.
For anyone reading this, i tried to reflash the stock nf9 kernal to see if that was the issue, but i got a restart about 4 hours later. I am going to reflash the firmware via odin and report back.
I am having this issue for a long time. i have done everything, and finally i gave up, as i think it is a hardware issue. what make me confuse is the problem start since the day i upgrade to kit-kat. with every firmware come out i have a new problem. the latest "NF9" my phone just hang and black screen untill i press the power button for 30 second, then will restart. what make crazy is that it shuts off at night, and when i woke up i miss the alarm.
I'm sad to report that the reflash didn't work. I reflashed the NF9 firmware using odin about 4 days ago and it was fine for awhile, but I got 2 reboots today. I'm not sure what is causing this, but I am still open to suggestions. I don't think its hardware related since it didn't do this before kitkat. I still have my samsung warranty until february I believe, so if worst comes to worst then ill have to send it in, but i'm not sure what they will do about it.
The only thing I havent tried is replacing the sim card. Could a sim card cause a reboot issue like this?
i have already done it, even the SD card, still same problem.
Is there some kind of log feature in android that logs crash events or errors somewhere so i can maybe figure out what the problem is?
by the way i think i have solve my problem by updating busybox and supersu. i had to install busybox to system/xbin. and since that day i haven't encounter any restart or freez. almost 2 week. i hope that fix your problem as well.

I do not have busybox installed, and SuperSU is up to date. Also, the restarts happen with or without root ie without SuperSU. I still dont think its an app problem.
Just an update for anyone reading this. I have installed SetCPU to manage cpu clock speeds. I have had it installed for about a week and have not had an update with my custom profiles. It seems the restarts occur when cpu speed is at about ~675MHz. Not sure if its hardware or software yet. Any help is appreciated!
Update. I sent my phone in to samsung for repair. It looks like they just reflashed the firmware. After having it up and running again for 15 minutes the phone rebooted again. I contacted samsung and they recommended sending it in again. I'm not sure if it's worth it to send in again or if i should break my warranty and flash a custom rom. Any suggestions are welcome!
I get restarts because the modem crashes... its a known issue apparently

I cant believe its taken over a year for this issue to get fixed. Im almost positive its a software issue since it never happened on jelly bean. It's strange that not a lot of people have this problem though. A lot of people must have already flashed custom roms I may send it in again since I still have knox 0x0 and see if they do anything else besides reflash the firmware this time. If they only do a reflash again i will just flash a new rom and hopefully everything will be fixed
Final Update:
I sent my phone back to Samsung, apparently my issues were a hardware problem. This time they replaced the "PBA assembly" aka the mainboard. I have had the phone back for almost two weeks without a single restart. I believe my restart problems are over. I hope this information helps anyone with similar issues. I would recommend sending it to Samsung for warranty repair if you are still under warranty. :good:

I had the same problem but already tripped knox so iffy on sending it in. Funny thing is I did the external sd write fix and the phone has not rebooted since, going on 3 days.

I would get reboots even without an SD card put in the phone, so I don't think that would have helped me. I havent had a reboot since I've had the device back
Here's the story. I purchased a factory refurb'd Tab Pro 10.1 (SM-T520NZKAXAR) on Woot a few weeks back. I live in Canada, but it is a USA tablet, if that matters. It came with a 90-day Samsung warranty. As soon as I got it, I started looking at custom ROMs. I have experience with custom ROMs on my HTC One m8 (and old m7), but not with any Samsung devices. I wish I had kept it stock for a few weeks first to check it out, but here we are.
I created a nandroid backup of the stock firmware, however I quickly deleted it during a wipe when flashing my first custom ROM, which was GraveD's v3.0. It seemed to go OK, but then it would start to freeze up and reboot on it's own. This seemed to happen mostly under load, and especially when trying to install apps from the Play store. I tried going back to the stock kernel, thinking that could be the problem. It stopped the crashing, but then wifi wouldn't work. So I could choose between having a tablet that crashes all the time, and has difficulty installing apps, or one without wifi. Both were basically useless.
I tried installing another custom ROM, GigaWatts Pro. Again, flashing seemed to go well, and the ROM also seemed to work very nicely for a couple of days. No random reboots, and wifi worked great. I spent a few days downloading all of my apps and getting things set up the way I like, when yesterday something went wrong. Perhaps the tablet lost its root (is that possible?). All of a sudden, apps are crashing all over the place (Unfortunately, [insert app name] has stopped). Titanium backup hangs at "Asking for root...". Installing apps is also difficult again. The tab doesn't reboot on it's own, but Play Services crashes constantly. Whenever I try to get into developer options, the Settings app crashes. I'm not even 100% sure USB debugging is enabled right now, although I'm still able to flash using ODIN.
I tried doing a factory reset and re-installing GigaWatts. Same problems. Tried making sure the root was OK. Same problems. I've tried using twrp 2.8.0.0 as well as 2.7.1.0 with no luck.
Right now, I've downloaded the stock firmware for Canada T520UEUANI1 4.4.2 (although the tab was bought from a USA site). I assume this also installs it's own Kernel. It shows Kernel version:
3.4.39-2776001

I'm experiencing the same problems. Google Play Newsstand crashes every 10 minutes or so. Settings is almost useless. Installing apps is problematic.
Can anybody tell me if there's something I'm missing? Anything left to try? Does it sound like a hardware/ROM/kernel problem? If it's hardware, can I still utilize the Samsung warranty after trying to flash custom ROMs? I'm going to try to download another Cellular South stock ROM, but it seems like the problems are persisting regardless of which ROM i have installed, so I think it's something else (kernel or hardware-related).
Any help is GREATLY appreciated. My new tablet is basically useless, and I've run out of ideas.
Try this latest firmware since you mentioned your tablet is the XAR model the firmware should be cellular south (wifi)
http://www.sammobile.com/firmwares/download/39630/T520UEUANK1_T520XARANK1_XAR.zip/
If that doesn't help then it could just be a bad tablet .
(btw when you flashed a custom rom you probably tripped the hardware knox flag and voided any warranty it had, I guess you could play dumb if they ask and say it came like that since it was refurbished, and hope they still repair/replace it)
I just tried the USA cellular south firmware. Still experiencing the exact same issues. I'm completely out of ideas. Does anyone else have any ideas? Otherwise I'm going to have to try warranty service and hope for the best. Is there anything I can do to restore the Knox flag before I send it in?
Also, in download mode the tab is recognizing the system as custom. Is this normal after flashing a stock image?
So do a factory reset in recovery, and clear the cache also. Then load the cellular South file thru Odin. Then factory reset again. See if this clears your problems.

I've tried the Cellular South firmware to no avail. I'll be trying to warranty the tablet now. Fingers crossed!
