Samsung Galaxy S7 Edge Gray Horizontal Bars on Screen I recently purchased the Galaxy S&amp; Edge, but as of yesterday I have been experiencing a strange problem with the screen. The screen is divided into sections, alternating between sections of normal color and brightness, and sections where the color and brightness seems darker. When I adjust the brightness of the screen to max, the dark areas get smaller and smaller until they completely go away at max brightness. The same goes for the normal areas at lowest brightness - they disappear. Obviously I don't want to keep my phone at max or min brightness all the time, so does anyone have any ideas how to fix this? I have tried restarting and clearing the system cache, and starting in safe mode, but to no avail.
Did you enable developer mode and modified some of its settings ? if so, try disabling the items you modified except USB debugging (if you use it), or directly disable developer mode. 

Hope that helps
