Samsung s2 crashing - Galaxy S II Q&A, Help & Troubleshooting

Just flashed resurrection, but I have been having this problem for awhile. My phone will start up fine, then while updating facebook or downloading apps. The phone shuts down instantly. I tried to reboot but gets stuck in boot screen. I have to recharge the phone and try again. When phone is charged, I'll reboot and have to try several times to get to the lock screen. During this time my battery will how erratic battery voltage readings. Any ideas?

Does it happen on full stock? Stock ROM, stock kernel (root while you flash it using mobile doing pro if you like), but don't use a custom kernel. See how you go.

Thanks, it does it on both stock and custom rom. I conceded and bought an s4. Thank you for your help.

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?

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.

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.

S3 keeps rebooting

Hi!
running on 4.0.4 for mideast, was working fine then y'day the phone app crashed 3 times. I wasn't able to make a call one time. Restarted and worked fine. This morning it just started to restart, and kept restarting from the samsung logo, didn't properly restarted.
I removed the battery, and it was fine for some time and then began the whole restarting circle all over again!
Any help appreciated!
Give more details. Did you do any firmware upgrades or any custom ROMs?
I'm running official firmware.
Or any apps you installed yesterday? Is your phone rooted?

nope! did not install anything at all in the past 2 days.
If you haven't done so. Backup your files and factory reset.

[Q] My phone is randomly restarting?

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...
Backup and factory reset

...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.

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

I'm gonna dl and install some new jb rom while im at it. I have clockwork installed already. I'm new to android but have watched some videos about it so it wont be a problem.
I would say install omega,its fast and stable.
Omega for touchwiz and stock look
If you want the jb look like the nexus there are also many roms like that i think foxhound is one check tem out
Ask me if you have problems glad to help

CM11 keeps freezing

The 12/27 nightly was running along finely for a couple of hours, changing settings and such. It froze after i changed a ringtone and now itll freeze after every bootup and sometimes it wont wake up. Then it will freeze within 1 minute after unlocking the phone. I correctly wiped/flashed everything cm11 coming from cm10.2 with latest kk-gapps and the latest ktoonz kernel. any ideas?

Bump!
I'm facing the same issue with my Note 2 here. I flashed it using TWRP 2.7. Does anyone know if this makes a difference?
As CM 11 20140328 basically made my phone useless I wanted to switsch to Omnirom. As i did a full wipe and installed it, the phone crashed every few minutes. The display stood on though and pive wallpapers were still moving. So I went back to the latest CM 11 nightley and now my Phone keeps crashimg every few hours. But its just like with Omni. Display keeps on and stuff but I cant do anything. Im running Boeffla 2.2 kernelnand TWRP 2.7. I actualpy switched to TWRP because I thought it could help.
