I have a green line running vertically down the camera screen of my ZTE Warp 4G . That green line appears on every picture I take. It is about a quarter of the way in from the left side of the screen or picture. If I zoom out the line disappears, but it will still appear on the photo. I have to removed the battery and restarted the phone and nothing seems to remove it. The phone is only 3 weeks old. Any advice would be greatly appreciated.
