Screen won't turn on after time out

[sidharta87]

Hi guys, a weird issue here. Can't figure out if it's hardware or software.
I have this S8 for about a month, and since a few days the following happens:
When the screen times out and goes off, it won't turn on again. I know the phone is working for about a minute more (what's is connected on the pc) and then it just shuts down. To turn it on again I have to do the hard reset (volume up + power).
I tried wiping the cache and then formatted the whole phone, but the problems persist. Any idea what could be the problem?
Cheers
Daniel

Hi, is this the original battery?
