[Q] My phone is randomly restarting? - Galaxy S III Q&A, Help & Troubleshooting

Hello, I was browsing with Google Chrome on the SGS3 when all of a sudden it reset(which is not uncommon...seems to be a Chrome thing), and when the lockscreen came back up the LED flashed blue, and the screen went blank. 5ish seconds later, the lockscreen reappears, I have no service (literally the circle with a line through it) and after a few seconds I get the blue LED flash and the cycle repeats. For almost 10 minutes straight now. I have not tried to get into recovery mode, but I have removed/reinstalled the battery.
Any ideas or suggestions?
The only thing I can think of is that it was in a backpack on a hiking trip today and got very hot. It wasn't in use during that time though, and I hadn't seen any errors with it for at least 6 hours afterward until this happened.

More info, I have stock everything. Touchwiz launcher, etc...

...just did. Sadly, I did not have a way to backup anything because it was in the reset loop (or whatever you'd call that)
What could have caused it? Is it an issue with the stock ROM? I have custom ROMs on all my other phones, I was waiting until the SGS3 development matured a bit before I dove in, but now I'm not so sure that waiting is a good idea...

Maybe caused by apps that you installed.

[Q] Grr, had to restore to factory, why?

After using an app called TS 2 which encrypts photos and videos, my Allstream began bootlooping. It would get to the Sense touchscreen, and as soon as i pulled the ring up, boot loop began. What was the possible cause of this ?
Also, I've been spending the last2 hours getting my tablet back to normal.thankfully, all my music and data is backed up online w google or Picasa or etc.
Related question:
Though, like my synergy Rom on EVO, is there a way to enable the jetstream to automatically Download all the apps again when a flash or restore occurs? Is root needed for that?
If you checked Google to backup your apps, your apps should reinstall minus the data.

Ok. Really unhappy now. I rebooted my device after spending hours yesterday restoring it and it is still bootlooping after a factory reset. When I pull the lockscreen run, it crashes and reboots. Please help.
Possible causes?
possible fixes?

is there a chance your issue is related to that thread?
http://forum.xda-developers.com/showthread.php?t=1306673
i never had bootloops myself, so i cant quite help. sorrys.
I'm unsure. I was on WiFi when it happened. I don't know of that makes a difference. Also, I had screen rotation off, so I was unable to rotate to check.
Could this glitch be fixed with root?

Also, my jetstream does not bootloop on its own. It only happens once I tell the device to reboot.
I'm afraid to reboot it now lol. It's done it twice and the hours I've out in to restoring it is not cool.
I need nandrioid!!

Yea, I see that now. Can't get to mu pc to root til tmr tho.

Settings app not opening

I've noticed that in the last couple of days, the Settings app doesn't work properly. At times, when I open the app, it just opens for a second and goes back to the home screen. After some time, the problem goes away on its own. Sometimes, taking out the battery and rebooting the device helps. Sometimes, it doesn't work. Anybody help me out here?

I am not really sure but this might be happening due to a virus or malware. Which RoM are you using?
Sent from my GT-S5830 using xda premium
Stock Gingerbread. 2.3.4!
Try installing any free antivirus and scan your phone. I recommend Netqin

It can also happen if you apply a wrong patch, or flashed something that was not supposed to be flashed on a stock ROM.
Sent from my GT-S5830 using xda premium
No viruses, never flashed or patched anything! :|
maybe because cache is full, can make phone become crazy sometimes.
moreover u said ur on full stock rom without any modification. pure stock rom stores cache in phone memory and it'll be full and cluttered overtime.

Thinking of taking back my S3 due to force closes??

I've been getting too many force closes with my S3... It happens with many apps and sometimes it just gets stuck for like two minutes which I can't do anything until it comes back. Have you guys had any issues? I don't know weather to take it back or do a factory data reset...

Sounds like something you installed is causing it. Factory reset it. Force Closes are typically software related.
Its happened to me a couple of times as well on the gallery and tapatalk 2 app. It is few and far between so it doesn't affect me too much.

OK. I'm going to delete some apps that I don't use and restart. Maybe it's one of those... If not, I'll factory reset it.

I currently get on XDA through my app right now...just searching for a thread listing forever...and if I hit the profile option it force closes.
Worked fine for the last week but nothing now!
Happens to me a lot when running touchwiz launcher I am now using apex and have had zero crashes. Although with android its like windows you will get force close just like windows gets blue screens its just one feature of owning an android phone but it rocks.

I used to have this problem on my OG Incredible, (haven't yet had it on my S3) and I would usually solve it by uninstalling/re-installing or clearing data on the apps that would force close. If every app is FCing though then it may just be easier to Factory Reset.

Slow operation, keyboard and battery issue

Hi,
I have 3 issues. Hope somebody can help:
1: Phone operates too slow. For example when I go to menu, app icons take around 5 seconds to appear. Similarly when I go to home screen it takes the same lag. So much delay that I could capture the screen short. You can see that weather clock and alarm widgets didn't appear. I cleared cache several times n restarts but it works fine for few mins n then again becomes laggy.
2: Keyboard disappears after typing few letters and sometimes it takes several secs to get it back. Reappearing delay is may be related to the above problem of slow response but why it disappears in first place.
3: Battery doesn't charge despite the whole night charging. Its happens not do often but really bugging me. I noticed that whenever I get missed notifications like calls or msgs it stops charging. Not sure why it's happening.
Looking forward to some help from experts. Please note that I feel these problems are occurring more after recent update. I'm using stock Rom of intl s3 version.
Thanks

How to factory reset
http://www.jayceooi.com/2012/06/08/how-to-hard-reset-samsung-galaxy-s3/
Thanks.I have the latest stock firmware already. Do you think stock Rom is faulty? And I should root it and lose warranty. I can do that but is it the only solution?

Ok read It agaIn. Thanks. If thats the only solution, will wait for jellybean update that's just around the corner. I wondered if anything related to hardware or phone settings was to be blamed. But anyhow, thanks.

I am also on XXBLFB and facing no such issues. You should check if some app is not eating a lot of RAM.
Jelly Bean won't be available for this region anytime soon keeping in view the time it took S2 to receive ICS update here.
I suspect the same. my RAM doesn't go below 600mb even if I close all apps and clear ram from task manager. After restart, phone behaves well for an hour but then again becomes laggy. My S2 is much faster than this with lot more apps. This S3 is really disappointing me.

Try to find the culprit app. I have 100+ apps and set is still very very smooth.
Sent from my GT-I9300 using xda app-developers app
That's the status when I just cleared cache.
Sent from my GT-I9300 using xda app-developers app
my suggestion is to do a factory reset (after backing up your contacts, messages, notes etc). then download your apps again and note the behavior of phone after each app. You might find the culprit then. It doesn't seem like an issue with the update since I also updated mine. Also very less likely its gonna be hardware issue.
Sent from my GT-I9300 using xda app-developers app
Maybe the CPU is not working at its entire power. If the factory reset is not working, maybe you should go and replace the device, before it's too late. When you bought it ? If the phone have less than 30 days you should get an instant replace. Not sure that JB will help you, as the installation isn't like a "full format" of your phone
Hard reset: *2767*3855# (no warning message before formating, so type it when you're ready, also remove the sdcard if you don't want wiped too.)
Or *#*#7780#*#* - Factory data reset - Clears Google-account data, system and program settings and installed programs. system will not be deleted, and OEM programs, as well as My Documents (pictures, music, videos)
Thanks. Will get in touch with the vendor for replacement (though I'm sure he will not agree that easily) or else will do a complete reset. I'm really pissed off for spending this much for getting this device. Samsung is very serious in pushing their loyalists away!

Sometimes, there can be some errors. You know, nobody's perfect and we are all humans. After one week after I bought my phone, I found that it have sort of scratch on the screen, but looked like inside of it. It could be seen only in high light. The vendor replaced it instantly. This one is perfect. Love it and is extremely fast and I have many apps on it. Good luck!

Check in task manager, you should have an idea about how is going bad. Also change the antivirus for Avast. Avast is much better. However I recommend without antivirus. I just scan sometimes my phone with it or lookout but never leave the antivirus installed. Is just a waste of RAM memory.
If nothing works do a full backup with Kies and do the complete factory reset.
Most of the apps will be automatically reinstalled when you add back your Google account, but you need the backup for settings and saves.

Uninstalled several apps. Removed widgets from desktops. But still same issue. One thing I'm not able to figure out is why my RAM doesn't go below ~600mb despite killing every task n cleaning cache. I guest a factory reset and ROM installation is the only way out. Thanks guys for all the tips.

Even with all the apps I have on my phone the RAM usage is around 580-640 (stupid SwiftKey using 45 mb most of time) and when I kill the apps I have 430 mb, slowly increasing til 530. Try reset, you have nothing to lose.

Phone locks up 10sec after boot

I can use the phone for 10sec after boot and then the screen freezes and doesnt respond to buttons but the status bar seems to be changing.
Last thing I was doing was uninstalling whatsapp, and some iphone 5 launchers with titanium backup and restarting.
What are my options?
You can go into recovery mode and wipe cache or your data maybe,saving your phone is a better idea than to keep your files(only removes your apps not photos or music)
Tell me how it went
