I have the same issue..the fingerprint reader works half the time..most times when it doesnt work its when the phone is in sleep mode with always on display showing..i swipe my finger and nothing happens...i have to press power button to wake it up and then i have to swipe my fingerprint to...
battery life on my ogp sucks..i got maybe 10 hours out of it with screen on 50% to 70%..obviously if i left the screen on 20% i would get more but the screen is too dark. my note 2 with the same screen setting got over 18 hours easy.
i dont see an option to disable thta on the stock message app..i use gosms pro n i have the option to not have the screen turn on when gettn new messages..
btw how much ram mem does your phone use on average?
my optimus g pro uses alot of the 2 gb ram mem...most of the time i have 1gb to 400mb free only..what uses all the ram and is this normal ..im only asking because my note 2 used well less than 1 gb of ram.
Mine does the same thing..thought it was the phone so I exchanged it but same problem keeps happening to new phone..both times it stopped working was trying to view youtube in landscape...it wouldnt work..only a reboot would fix it..hopefully a fix is on its way.
