[HELP] Apps constantly crashing and preventing use

Hi guys,
I have had the Galaxy S2 for just over a month now
I have not installed any custom roms. I've just updated it once and then rooted it after that.
I have had very little problems with the phone so far. It would rebooted by itself 2 to 3 times but it worked just fine.
The problem began when I turned my phone off. I can't remember why but I did and when I turned it on again apps would be crashing left right and center.
I pretty much have no access to anything since the crashes occur constantly.
It's the normal crash notification you see on the phone
ie. Sorry! Application xxx (in process xxxx) is not responding
ex.
xxx - TwLauncher
xxxx - com.sec.android.app.twlauncher
Pretty much all the applications that run at startup (including widgets) crash
I would click on "Force close" to get rid of the pop ups but
Logsprovider and Calendar Storage continue to crash making it impossible to use that phone
Any help or thoughts would be greatly appreciated!!
Thank you guys
I would try going into recovery mode and doing a factory reset, should sort it out.
Sent from my Galaxy S II
is there no other way? i was hoping there was a way that fixed the problem but also retained my applications and data...

[Q] Samsung Galaxy S3 i9300 restarts in lockscreen

Hi, I have a samsung galxy s3 i9300 and I started facing a problem. Whenever I make the device go in sleep mode be it by pressing power button or a widget it hangs while unlocking it. Sometimes unlocks after 2-3 mins and majority time it restarts. But whenever I keep a task in background like the "awesome on off" app to unlock my phone it works perfectly. Please help. Im rooted and tried many roms including stock but the problem remains. If I turn off the awesome on off app the phone again starts doing the same thing ie restarts.
Thank you

Can not unlock Samsung galaxy s2 after lockung screen

Hello to everyone!
Few days ago my phone started behave in strange way: it manually reboots after locking screen. No matter how screen was locked: by pressing button, automatically, or even when it locks when I'm calling somebody.
System was CM 11, but now I have installed CM 12 snapshot. The problem is still present even after reinstalling system.
Maybe, someone also experienced this problem?
I would be glad to hear any suggestions.
I haven't noticed any other troubles.
