Help issue with camera

[1edog]

hi everyone, this is my first post, great forum. I've been experiencing issues with the camera turning on while watching videos. And even during the during the Hot Pursuit demo. It will make a box in the left third of the screen with the view from my camera cutting into the view of the video I'm trying to watch. My question is do I have a defective phone and should send it back or is there something I need to do to correct this issue? Thanks and looking forward to your replies.
