Moto E (4th Gen.) - Screen turns black
Customer Issue:
When outdoors, the Moto E4 screen turns black when I turn it from landscape to portrait.
It comes back on when I switch back to portrait mode. I can't take photos in landscape, etc.
Solution: Take off your sunglasses.
Basically, it's a polarization issue. The alignment of rays from the screen in landscape is going to be cancelled out by some polarizing sun glasses.
