Random reboot or phone turning off with over heating - Galaxy S II Q&A, Help & Troubleshooting

Hi guys. Im using the international version of GS2. My problem is that my phone switches off suddenly with over heating or reboots randomly. I have used different ROMs and found this problem persisting. I cleared everything from my phone, used tools like GS2ROM nuke and GS2ROM Wipe but still this problem is there. I read a post saying battery may be faulty and replaced my battery even. But no luck. I found that the over heating and switching off occurs only when screen is off. During continuous usage, it is more or less fine. (except for occasional random reboots). also, this is always random. it doesnt make any sense. i even checked the hardwares of my phone in the service centre and he says the hardware is fine. Pls help me guys. Im going mad.. :crying:

Somebody help me pls.. I think its a serious issue.. :crying:

same problems here...
An answer would be nice!

Guys its driving me crazy. I cant use it at all.. It gets heated up and turning off or reboots randomly. :crying::crying:

No bud. Not working. How about you?

I am a huge fan of custom roms and have flashed many of them, it was all fine before. but suddenly, this problem was omni-present in all roms. :crying: So i flashed the stock ROM version 4.1.2 (INDIA- XWLST) via mobile odin. it booted well after wiping cache and factory reset and was fine for a couple hours. After that the problem got massive. phone will restart or turn off when in screen-off. This continues even now in stock ROM. I tried everything from wiping cache, factory reset, dalvik cache wipe, fixing permissions and everything. But no results. THE MOST BIZZARE THING IS THAT PHONE IS FINE WHEN SCREEN IS ON. I experimented by keeping the screen on for an hour and nothing happened. THE MOMENT I PRESSED THE LOCK BUTTON, IT RESTARTS. Im going mad guys.. someone help meee.. :crying::crying:
EDIT: I think there's nothing wrong with the power button because it works well in all other places. If i remove the battery and reboot, I get a few seconds where i can lock and unlock screen. But again, it starts.

No can do guys???? there's no way to make my phone alright??? :crying:

SGS3 keeps rebooting randomly

My SGS3 works just fine for 2 weeks, until now.
Suddenly, it keeps randomly crashing and reboot into samsung s3 logo screen.
Oh, I have tried different roms (and stock rom also) but the crash still happen.
I also have tried wiping cache, dalvik, clean install, removing external sdcard, and restore factory setting. But none was effective.
Any ideas?
I had a similar issue with my Atrix and it turned out to be the SIM Card. Had it replaced and no more random reboots. I figured this out by checking the panic dumps...maybe there is a similar way to check this on the SGS3

Thanks for the response.. I tried it just a moment ago without sim card, and it still got the random reboot..
Any other people who got the same problem?
Is the phone unusually warm? The phone will automatically reboot if it overheats, but that wouldn't normally happen unless it's been left in the sun or overclocked.
I can get mine to go into a reboot loop if I play Asphalt 6 while outdoors, but the problem goes away as soon as I let it cool off for a minute or two.

yes, the phone (when i use it) is usually warm, but my phone also crashed while not in warm state.
but this crashing-reboot problem just show up after 2 weeks of normal (and not any crash experience) usage.
this crashing problem show up after i played temple run btw (not sure is relevant)

Sorry to hear that man. Had a SGS with same issues. maybe Samsung has hurried releasing galaxy S3
I'd factory reset and only put on the important apps you use. Depending how long it takes for you to normally get a reboot you can slowly add new apps back to narrow it down. I had the same problem last year and thought I had a bad sgs2. But it turned out to be dolphin hd browser at the time that caused it and haven't had a reboot in a year. It could be something similar in your case. Hopefully its software related and not hardware

i just tried flashing normal ROM, after booting to "get started" page, approximately 3~10 seconds, my sgs just rebooted over and over again, until it show only black screen with battery icon on it (i think it may be charging animation while the phone is turned off).
ahhhh this is driving me insane!!
update : i just flashed hypergalaxy ROM and currently it is stable and not experienced crashing (yet ).
i'll give further report later today

Have you tried reinstalling FW with Odin? If yes does it still reboot after a factory reset with nothing installed?
yes, i have tried flashing stock rom using odin a few hours ago, but the crashing still happen.
my sgs3 now stuck at boot-standby5sec-crash-reboot loop.
so, i decided to bring my sgs3 to samsung service center tomorrow. hope they will replace it with a new unit
UPDATE : Samsung replaced my new SGS3 with a new hardware (not sure new device though, the flash counter reset to zero )
the problem seems to be hardware related
thanks for all your reply to my problem

I am having the same issue, I've had my phone since Saturday (6/23/12) and it crashes, reboots, apps crash, internet crashes, email crashes, etc. I can udnerstand a lot of apps may not be updated to ICS.. but no matter what I do.. everything crashes.. It's a bit ridiculous. I am a prior iPhone 4S user and am probably going to return this phone. I can't do much without it crashing or the screen freezing.. not being able to do anything for 2-3 minutes, etc. And they couldn't port any of my numbers from my prior phone because they didn't have the software update to do so yet. So overall, bad experience with the Galaxy.. and maybe I should have waited longer before buying this phone to work all the problems.

I'm very sorry that u have these problems.but there will always manufacturing faults when making so many units.only one thing to do,return it and get a replacement.when u get a fully functional galaxy u won't regreat it,it's a awesome phone.Samsung usually replaces the phone,so I think they will do the same in your case.anyway best of luck
After all the problem I've been through, finally I send my phone back to samsung service center.. they tried to reinstall stock rom several times, and in the end, they change the IC board to a new one.. and it does solve my probs..
SGS3 tebooting
Hi guys here is a peace of my experience
Bought the phone last year in November .2 weeks everything fine then it starts rebooting itself.retun it to the mobile provider and get it back in 3 weeks with conclusion that they experience the reboots as well and that the phone had some kind of software issue.in 3 hours i was back in the shop with my phone rebooting again.they send it again to service got it back yesterday with 4.1.1 android and they sad it may be caused with wrong customizing or not supported sd card,turned on the phone and had few reboots manage to update to 4.1.2 and today heavy gaming internet etc and no reboots so far.will test it till wendsday and see what happens.if it will reboots again then its going back to service and this time it is the 3 time so i will get a new phone.

random freezes (with CM roms)

Hi, I had CM10.1 running for a while. Since a few weeks I got random freezes when I wanted to turn on the screen it stayed off (LED was flickering, so the phone was still on). After a forced reboot (vol up+power button) it worked, but as it kept happening I wanted to try a full wipe. By the way: it happened every single night too, my phone was flickering its LED, but didnt react, and also alarm wasnt working (FML).
When messing around with this (I'm not really an expert at flashing/CM) and trying to restore my phone with TitaniumBU it kept freezing when working (to) fast. So I tried a lot with formatting SD, doing other wipes etc. Nothing really seem to help, as the random freezes kept happening.
Now I've installed the stable CM9, but already had freezes (even with the startup wizard in the beginning). I'm getting the feeling that its some hardware related issue. Can anybody tell me more about these problems, and mayb what else I can try.
Last try is to turn it al back to Touch Wiz, unroot, but I have to figure out how to. Hope this will solve it.

Sorry, plz move my thread where it belongs (im noob).
After some searching I found that it might not be a CM related problem, but something with 'sudden death' happening to more people with other ROMs or even without custom roms.

New development: my phone is now stuck at Samsung GSIII logo. Doesn't go further from there. I'm planning to go to Samsung with it. It is not unrooted, so my Q is;
can they see that it is rooted when the phone doesn't get past the boot logo?

Constant reboot not caused by rom

My note started doing this after it went through airport security. It was in a bag and went through the x-ray machine. It randomly reboots very often, probably between 20-60 second intervals. I was on CM10, then I flashed back to stock ICS, and then finally up to the official JB update. None of which has solved this problem.
i posted in here.. this may help.

Phone is stuck in a boot loop and this is what I know so far. Phone is on stock ROM, power button is working fine, I can get to recovery and OS and download mode, and while phone was charging I took the battery out and the phone keeps vibrating. I now know it's a hardware problem for me (I think), but I can not pin point where. Any advise would be helpful cause I really love my note and this is just breaking my heart.:crying:

Phone keeps turning off sometimes if droped or whatever.[e120l]

sometimes my phone just reboots itself, popping the back i did realise that there is a scrue missing, but i dont think thats the issue. Also, sometimes the battery stats are wrong. The phone is rooted and i just completly wiped it.
Thanks in advance

Need Help with My Note

Okay, Now I know I am not the only one with this problem. Also, I know I am one of the FEW people who have this problem.
Story:
I bought the Note the other day from someone, they claimed that the note was stuck in a boot loop. I purchased it, Did a factory restore etc. The phone came on and was working perfectly. THEN the battery died, now I understand what she means by stuck in boot loop.
What happens:
Phone turns on
Starts up
Freezes after about 2 minutes
Reboots & Repeats
Now there have been a couple times I can get it to stay on for about 12 hours then it will just freeze and reboot. I have tried factory firmware restore, I have rooted, I have tried custom Roms, I have unrooted, I have done stock rom. The battery is NOT bad, it holds a charge perfectly well, the Power button is NOT stuck. I have no idea what else I can do, I have tried just about everything and looked all over this site for the past 2 days trying to figure out info on this problem, but so few people are having it that it is basically just looked past.
Any help is MUCH appreciated and I will be very grateful if this issue can be resolved.
Have you tried removing the battery / changing the battery / using a different usb/charging cable/ac-dc adapter? Then clear the cache and dalvik cache and reboot. If you can get it to stay on for 12 hours I doubt that you have a serious problem.
Power button perhaps?

Not sure about power button on this one. It wouldnt freeze, it would just reboot.
I question software on it. If you can get it running long enough to find out what it is running.
I might question more, is it running OS for the right device or possibly was it a clean flash?
Sounds like its running an older 4.2 JB rom......notorious for random reboots. Could be a rom that just may not work on you phone. Mine could run all except Carbon Rom. Dont know why, just couldnt. No biggie, plenty out there.
