Two days ago I got the official update of jelly bean 4.3 to my Samsung Galaxy S3. Last night phone was dropped from a small height. Today morning when I switched on the phone it worked fine. But in the evening, suddenly my phone restarted and goes to Samsung Logo Splash Screen (Samsung galaxy S3 GT-I9300T) and keeps rebooting. I removed the battery and insert it after a few second. After that the phone worked fine and again the same problem happened.
If I remove the battery to switch off the phone and if I insert the battery again, phone switch on by itself (without press power button) and keep restarting.
I try to open the Home + Volume Up+ Power On button option. But is not working. If I plug the phone to charge, gray battery shows and again restarting to charge. (I mean, phone won’t stay in a stage).
If i try Home + Voulme Down + Power On option, phone shows the download mode for 5 seconds and restarts again.
So can you please let me know it’s a software problem or hardware problem? If it’s a software how to fix it ? ( I tried the emergency firmware recovery through kies, but kies couldn’t fine my phone).
