So.. where to start.
I bought my SGS3 in september. It's an international version (GT-I9300 ..XXEMA2). Phone never dropped, never had contact with water, used and handled with care. It used to work just perfect untill i think February, when if first time freezed.
I was playing some kind of game (not a heavy one) and it jsut competely stopped responding to anything, so my only option was to remove the battery and restart. After that it work quite a long time without any flaws. In late May, I guess (I can't quite remember exactly) it started to just freeze like once in a week or so. By the end of June is started to freeze like 5-10 times a day, then it got even worse, after reebot I had like 3-5 minutes before it will freeze again. It doesn't really matter how I use the phone. I can play games and it will freeze, browse, text, or just put it in my pocket and when I need it it's frozen. So I've read alot (and I mean ALOT) of stuff aboit it including this thread.
Tried everything. First I wiped out the cache, didn't help whatsoever, then I swithced to basic TouchWiz (from Nova) just in case, didn't help either. I tried removing all widgets (thought maybe RAM was overused) that didn't help too. Erased the Facebook app, cause somebody told that it may cause the problem, still freezing. Then my only option was to Factory reset. Didn't back up anything (except for pictures, that I didn't even put back on the phone anyway) and reseted it. For first day it was working nice and clean. The other day it started freezing again and I even didn't dowload anytning. So I skipped the part "reinstall one-by-one.." cause it's still freezing, so there's no point of that. But it surely reduced the amount of freezes..
So my only hope was rooting. Yesterday I've rooted it to CyanogenMod 10.1 (which is android 4.2) thought updating to later version will help me, but sadly no. Phone is working nice and smooth (when not freezing) but it have frozen for like 3 times already and you can't rely on it. When I pick it up it's like a dice game will it respond or not.
As long as anything from these tips didn't help should I consider unrooting it and take it to service?
Thank you for your time and have a nice day.
P.S. I would also like to know (just out of curiosity) whenever i have to remove the battery or do hard reset it drains like 5-20% of a battery. Even if I restart immediately after freezing today it jumped all the way from 29 straight to 10. I wonder what's that about..
