Looks like something broke in android. Factory reset should do the trick.

I have similar case like this on my other phone but the problem with it is I accidently dropped it while playing then every minute randomly it would restart, I try deleting apps, files but after the restart all files, apps is back like nothing happen. Try to update your phone, or Factory reset if it would. but if not it might have similar issue memory problem or something.
