I have a Samsung Galaxy S4, I didn't root it or anything at all.
During the last week my device suddenly shows me that I have 0% battery and keeps restarting itself like crazy, the only way I fix it is to just charge it again, sometimes this happens from 20% battery and sometimes from 70% even.
Does anyone know what the issue is?
Do I need to format my device totally? If yes then how do I do that?
Thanks a lot for any help.
