My Galaxy S3 shuts down by itself randomly. When it is shut down, it doesn't starts up by pressing power button. I have to take out battery and reinsert it and then press power button to start my cell. it happens even when battery is more than 80%. I think this problem is occuring when I goes to an area where mobile jammers are in place, but not very sure.
Can any one help me for the solution of this issue.
