It sounds like the phone is rooted correct? if so, what carrier are you on?

Well need to get this moved to the appropriate s3 forum so other people with your phone can help diagnose the problem

I think you just have to do wipe data and wipe Cach / Dalvik Cache by the way this will erase everything you've got

So a basic Factory reset should do?

Not sure what do you mean with basic reset but you should go to recovery mode to wipe data and wipe Cach / Dalvik Cache

What I mean, from recovery there is usually a factory reset setting, it basically wipes the data and cache partitions.

also in most roms there is a back to factory reset option that does the same thing, reboots the phone and proceeds to wipe data and cache partitions.

then try it and tell us what is the result
