My SGS2 (original AT&T version) has started rebooting randomly once every 3 or so days. It doesn't appear to be triggered by any single thing or event. The last time it happened was when I was opening the Market. The device rebooted back to the Samsung Galaxy S II boot screen.
I've been pretty careful with the phone (only installed trustworthy looking apps, etc). The phone never rebooted in the first 30 days of ownership. Sometime after that it started rebooting with increasing frequency.
Has anyone else run into this problem?
I also had this issue. I returned my phone for another one. I havent had the issue on the new phone but I am crossing my fingers that it doesnt start doing it again on this new device.
Thanks for the input. I had an Atrix that also exhibited this problem after 3 weeks of use. Based on the similarities, I figured it must be something in common on both devices.
At first I tried removing the microSD card I had installed (same one I used in both devices). I still had reboot issues after removing the microSD so it probably wasn't the source of the problems.
I finally realized it was the Dolphin HD browser that was always 'involved' in the reboots. I noticed that I could sometimes trigger a reboot by exiting the browser. The device would stop responding and then reboot after a small timeout. Sometimes the reboots would happen after opening another app, but it was always preceded by exiting Dolphin HD.
I found a thread in the international SGS2 forums that talks about this issue: http://forum.xda-developers.com/showthread.php?t=1321612. It seems that it doesn't affect everyone, so it may be just be some combination of settings / installed apps that triggers the reboots.
For now I've uninstalled Dolphin HD and am using the stock browser. I'm going to use the stock browser for a while and see if removing Dolphin HD fixes the issues.
EDIT: To clarify, this only appears to happen if I 'Exit' the browser. Leaving it running in the background doesn't appear to cause reboot issues, which may be why I didn't run into this issue until now.
That looks really strange, dolphin never gave me any issues. However you can try using opera browser that is my main browser and supports all the features.
Soft reboot (back to bootanimation/homescreen) or hard reboot (back to Samsung screen)?

It automatically reboots back to the Samsung Galaxy S II screen. It then proceeds to go through the AT&T boot animation and finally ends up at the home screen. I assume this would mean it's a hard reboot?
I haven't had any reboot issues since I uninstalled Dolphin HD. I'm not sure if it's truly caused by Dolphin so I'm going to try a few more days without Dolphin before reinstalling it.
As a side note, I noticed some other issues which may or may not be related. These occur even with Dolphin uninstalled.
- Menu button sometimes not responding on the homescreen unless I go to 'Applications' and go back to the homescreen. Once I enter / exit the Applications screen the homescreen menu button will work again. Issue seems to be related to enabling/disabling the GPS from the notification bar, but I haven't reliably reproduced the issue.
- GPS not locking for long periods of time, even though it shows 6+ satellites in view. Sometimes it will lock within 10 seconds. My guess is some sort of AGPS download problem (maybe related to how supl is set to use wap.cingular?). A quick search on Google reveals a number of people suffering the same issue on the AT&T SGS2. All posts also indicate that it worked fine for 5+ weeks before GPS issues started to show up.
I'm trying to hold off on resetting my device back to factory defaults. I want to track down the problem instead of just assuming it was some bug that won't happen again. Based on the international forum posts, the Dolphin HD issue will come back eventually even with a reset.
Thanks again for all the input and help!
Yup that's a hard reboot. An app shouldn't be able to cause a hard reboot like this, but it is not possible to debug. Stock kernels don't have ramconsole for crash debugging.
Hi everyone!
I saw this problem on every device I tried, it seems that with certain wifi networks an android device wouldnt allow to watch flash movie for more than 3 minutes, it just hangs, shows its buffering but doesn't. (need to refresh the page and get another 3 minutes...)
When I switch to some other wifi, it randomally occurs with some and with the others it never occurs.
I want to ask anybody who knows about it, what can cause this and how do I fix this? (this happens only with android, if I use my laptop it doesn't freeze regardless of which wifi I use)

I've probably encountered that, but I don't really remember it.. so, sorry but I can't help. Good luck finding a solution though.
Hey guys,
I know there has been a couple of posts like this that I have found through searching but none have actually found a solution, so instead of resurrecting a old thread I thought I would start a new one.
Basically I am having some issues with my new pebble blue (yey) S3 . I have found that sometimes when the phone is sleeping when I press the power button to bring it out of sleep the lock screen begins to hang. This is followed by a number of different things, the screen either glitches for a bit and then begins to work or it stays locked and needs a battery pull. As well as this I've found that randomly either when charging or not and the phone is sleeping it simply becomes unresponsive, staying on a black screen and needing a battery pull to fix (this has only occured a few times, the hanging lock screen occurs quite often).
I have done some searching and found little in the way of a solution or what the problem is, however I have found that when the lock screen hangs -if it begins to work again after glitching out the 'WIFI connected to ****' appears at the bottom of the screen. Anyway if anyone has any ideas or also recieves this problem I would really appreciate some help as it's driving me crazy and I'm unsure if it is a common S3 bug or a faulty handset, in which case I have limited time to RMA.
Cheers in advance
Hmm, sounds like a faulty phone to me. Try taking it back to get it exchanged for onother one. S3 was built to fly not crawl.
You'll want to go through a process of elimination to figure out when might be causing it.
Something you can try and test with (one at a time)
-turn on airplane mode
-turn off live wallpaper
-shut down all running tasks
-change your lock screen security method
-limit the number of widgets running on all the screens
-reduce the number of active screens
Probably other things you can try to pull out of the equation, but thats a good start
After looking up dial-a-phones returns policy it would seem that I have 28 days to return if the handset is faulty, so this atleast gives me some breathing room to try out any suggestions for fixes. I will begin to eliminate each of the suggested items above however as the lock screen problem is intermittent it make take a day so actually see if it has had an effect, which is annoying at the least.
On another note a numberupted of people are stating high battery life on their devices however mine doesn't seem to be as good and I do have power saving on as well as nfc etc. turned off. This makes me believe my handset could have a fault, but tbf I haven't allowed for a discharge to 5% and the recharging to 100% which I heare allows for optimisation of the battery.
EDIT**** I have changed the lock screen previously and found it had no effect on the problem and I do not have a live wallpaper in use.
Phone Freezing after reboot and auto wifi signal found on.
Same here, been happening the last few days after I installed Avast. Also, turning off and on the auto on wifi seemed to replicate the problem.
The phone will boot to the lock screen and freeze a bit, and sometimes the news ticker freezes, and then after unlocked, I try to turn off wifi signal has been found on the notification dropdown and then tries to auto connect to wifi, the phone will freeze up if I dont turn it off in time.
Once the auto wifi connect is off and reboots, then the phone will keep glitching up until it catches up processing alot of processes it was trying to do for about 1/2 hr. Also, if phone freezes up for too long, like after trying too many time of unlocking the screen while freezing up, the phone gets stuck at the lock screen and the phone almost overheated, in an area right below the battery. I had to pull the battery out to cool it off.
It seems to be a glitch in the auto wifi, especially if alot of resources are being used. Once Avast was on my phone about 1.5GB RAM is being used sometimes and since has really slowed the phone down. Going uninstall alot of apps.

Same problem.
No problem if Wifi is switched off prior to sleep.
No problem if Wifi connection is still available.
Problem to lockscreen if Wifi connection is broken (move away from connected router).
Any suggestion?

Exactly the same here. Driving me crazy. I did root the phone using the Samsung Galaxy S3 Toolkit. I don't know if the problem also exists on non rooted devices.
S3 black screen after unlocking
Has there anyone experience S3's screen went on black? I have pebble blue S3 - GT-I9300. Cases when unlocking, answering an incoming call or attempting to turn off an
alarm? Mine happens when after unlocking the screen then it goes black and screen becomes unresponsive. It happens intermittently and even after 3 times of
reprogramming. I am now going to have it replaced. I am having a lot of troubles -- it exits on its own when im reading or composing an SMS; files were deleted after
restarting the unit, and an app opens up even not touching the scree. This is expensive and I am paying a lot just to experience this king of inconvenience.

I also rooted my S3 a few days ago (with the S3 toolkit), and have had lots of problems with unresponsive lockscreens (I use PIN, because of exchange connection). It takes a few seconds or maybe up to as long a minute before I'm able to punch in the PIN-numbers. Before this the screen lights up but does not respond to input.
But the WiFi-connection issue might be what is the triggering factor, because after a boot it wotks just fine for several hours, if I'm not moving out of my current WiFi zone. First I thought it was either Secure Settings or Tasker that made my device lock up in this matter, but now as they are both uninstalled, the problem still occurs.
Are you running some kind of custom rom, or just the latest stock ROM, but rooted?

Just the latest stock ROM but rooted. I've found out that turning off the wifi power safe mode fixes the problem for me. To do this:
- In the dailer enter *#0011#
- Press the menu key
- Select wifi
- Press the on/off button.
The wifi power safe mode will however be turned on during boot. So rebooting will set it back on.
*#0011# seems does the trick. But is annoying had to do this every time after power off (change battery, change Sim, flying).... Anyway to keep the setting?
I am also on stock Rom and rooted. Interested to know any non-rooted phone got this problem?
BTW. I found a quick (at least quicker than pull the battery) way to get out of the forzen lock screen (sometimes forgot to do the 0011 trick): press the power button (screen will Dim instead of OFF), then hold the home button for few seconds, as soon as you see the "menu" and "back" button lit up, the lock is un-freeze...
A permanent solution is appreciated for such an advance phone....

Not that I know of.
Problem solved. For me anyway. Hope works for all of you having the same trouble.
My trouble begin with recent upgrade to LH3. My S3 was rooted by S3 toolkit v2.0. CWM installed was v4 something.
I un-rooted the phone. Uninstalled S3 toolkit v2.0. Re-installed the S3 Toolkit v5.0. Rooted the phone again (CWM become v6....).
I do not know it was CWM version caused the trouble or not. But my S3 is ok now.
I got it on my non-rooted phone, any additional solutions/suggestions? or service?
I found solution for problem . And my phone is working well. I downloaded rom file android 4.1.2 and flash my phone
JB 4.1.1 caused these WiFi issues on my phone

Exact opposite for me...never had the problem then since loading stock JB 4.1.1 with root I get lockups or freezes whenever WiFi is turned off or I leave my router's range. As soon as I disconnect from WiFi the whole phone freezes.
The *#0010# also locks up the phone when I turn off the WiFi power saving feature.
None of this happened before JB...and I replaced my phone with week via warranty due to this and the new phone does the exact same thing as soon as I upgraded to JB with root.
Any ideas?
Black screen / random reboot solution
Hi All,
I've had the black screen / random reboot issue for a few days. The only way to restore functionality on black screen lockup was to remove the battery.
I tried changing to Chrome browser and stopping the stock browser as suggested in some threads but it kept crashing.
I searched everywhere and most threads suggest a dodgy motherboard.
For me the issue was related to either a single PDF download via the stock browser or the fact I had quite alot of saved PDF files on my phone (S3 Stock firmware I9300XXELLA)
After deleting all the files listed in Internet downloads (look for Downloads with a green arrow Icon in apps) my trusty S3 has returned to normal. No black screen lockups, no hanging, runs like a dream!
I appreciate this may not solve everyones black sceeen issues but I haven't found any other thread with this solution. Hope it works for you.
Thanks,
Giz.

Thanks for the tip...
Was this happening on JB for you? You mention stock firmware (not familiar with I9300)...so I am guessing it was ICS.
For me the issues are with JB and I had no files at all in the Downloads folder after a certain point when I wiped / formatted the SDCard...so I do not think my lockups were related to PDFs. But I did (and still do) have a ton of music and a lot of movies on the External MicroSD Card....and quite a few custom notification and ringtone MP3s on the Internal SDCard. Next time I load JB I will run it a few days with none of this media loaded....

This is on JB 4.1.2, Phone had been updated to 4.1.2 for about a month. The issues started after a pdf download. Once all pdf's were deleted the handset works perfectly.

Hey guys. My S3 started freezing randomly a few days ago. What happens is that I will be playing with it and then it will literary become unresponsive along with the hardware buttons except the power button. The weird thing is that the animation on the screen is still active: say I was writing a text and the little blinking bar keeps blinking as if nothing is wrong but the phone is simply unresponsive.
I did a factory reset and it is still happening.
Anyone have any idea what the heck is happening? Is it hardware or software related?
Have a read of the freezing thread in general forum, sounds like the operating system is dealing with bad memory blocks.
Well, same thing happens to me, i looked up on that tread about bad memory blocks: well i even tested the memory and works fine, no bad memory sectors, my hardware power button responds to restart (no need to pull out battery). When it does freeze it doesn't unfreeze at all after some time ( i once let it unfreeze for entire night on charger and it stood on the same screen after 8+ hours). I even reinstalled a different software (JB 4.1.3 Darky edition) and it freezes very rarely now but when it does, it's still same kind of freeze. When it freezes it freezes mostly on Twitter app but sometimes random app. I don't know now is it really a faulty memory or just software bugs... btw dummy file didn't freeze my phone (to be clear) after i reinstalled the software, but did it before on old one
Help! Galaxy's freezing!
Hello,
I have exactly the same problem, when phone freezes nothing works except power button, when pressing it about 10 seconds, the phone reboots. I have exactly the same model (GT-I9300), but Lithuanian. The freezing lasts from 10 minutes to an infinite time. All the freezing started about three weeks ago, when google play started updating iron man game. I tried dummy file geterator, the phone hasnt freezed at all, but the phone freezes randomly when opening internet, other apps or just anytime, even when phone is on stand by. I tried flashing DarkyRom 4.1.2 XXEMB1, but the phone started freezing even more, then i recovered from the Nandroid backup, and the phone is now freezing not so frequently, about 1 freeze in 2-3 days, but it still freezes, and i also have a strange "Process com.google.process.gapps has stopped working" problem. I tried every solution to this problem, but none of them works. Also, i think it is somehow connected to the freezes, because after those messages phone freezes sometimes. I dont know how to solve these super annoying problems, because i tried nearly everything, and nothing works. I think this might be a hardware issue, and that i should buy a new phone. If you know somehing, help me!
The problem: The first 3 times, while i was online trough wifi on battery modus, it happened to me that of all sudden, the phone tells me, the docking station is connected, while i don't have it connected, not even have a docking station. And then the cursor jumps and it trys to play crazy until i cant operate it and need to close the phone. The first time when it happened, i saved my files and flashed the stock android 5.1.1. But it didn't solve it. The trouble came again. Temporarly i found a solution, i had to remove my custom launcher(i tried many! Also the stock one. The only difference is: Here i only have to clean the cache! ) while in safe mode and when restart all was fine. I checked with almost all free antivirus and antispywares apps, but there was nothing. It also removes allmost all icons after restart and then i have to install again a launcher and the icons will reapear and i need to rearange them again.
The best temporarly solution: After the 3 times, i managed to solve the problem, while leave it untouched and close wifi. It calms down that way without closeing the phone, don't know why. Don't know if its a security flaw, or just because i stay long on wifi. But it happens always when i browse the web and even with all browsers, stock and firefox and chrome. And then it continues to work normaly after i log in to my phone again, while the browser were i was surfing, i encounter as crashed, and i can go wifi again. I don't even know if its a hacking attempt.
But i just wanted to share this, it may help some, and i hope there will be a solution for this, thanks.
