I got Sumsung S2 from AT&T last June. It has been working fine until 2 days ago. The phone showed low battery and turned off automatically. I tried to charge it, but it looked dead. I called AT&T and they sent me a new battery and charger. I have been charging it for over an hour now, It is still dead and won't turn on.
I tried rebooting my s3 and it froze in the middle it shows the charging symbol when I plug it in but it still freezes I keep taking the battery out and in several times but it still freezes while it's turning on
