On my iPad Air 2 I get white lines on some areas of the screen picture. Usually on things that have a geometric shape like a window or something with tiles. What is that? Is there a way to get rid of that? Not a huge deal, but slightly annoying.
The stripes are called Zebra Lines and indicate areas of the image that may be overexposed. These lines are incorporated into many professional cameras to help the operator identify these areas quickly. While the lines may be annoying at first, they are a very helpful tool to make exposure adjustments quickly. I would try to keep them displayed if possible, many pros prefer them on.
You can get rid of them by selecting the camera icon on the right side and sliding the "Exposure Warning" off.
