For the first week its great (except my wife keeps borrowing it for selfies haha). Then suddenly the front camera stops working. Trying to activate front camera in any app (I tried LG Camera, Google Camera, Hangouts with Vid call) results in that app locking up for about 10 seconds then crashing back home screen on a pretty usable phone. Do it once more and the whole phone becomes unusable - even long hold power off won;t work, requiring battery extraction to recover it.
I have tried removing data and cache from the camera app and that didn't help.
Tried a software data reset (via the menus), that didn't help.
Just for kicks I enabled ART in developer menu to see if that possibly helped, it didn't (side note: ART seems snappy)
So I am at a loss now, next step after this is hard reset, but I am not optimistic that will achieve anything the soft reset didn't.
Anyone else encountered similar issues?
