Im having the same problem and the above solution does not work - have the white screen with the navigation bar and with full screen gesturtes.  I booted into safe mode and the white bar is still there.  When I have the screen fully dimmed , the white bar flashes a blinding flash every 5 to 20 seconds.

Try taking a screenshot of your phone's screen (hold the Power button and the Volume Down button at the same time for a few seconds). Then, look at the screenshot, and see if the white line appears in the screenshot. If you can't see the line in the screenshot, that would suggest that there is a physical issue with the screen and it would need repair.

This suggestion didn't eliminate the white bar. It covers up text on my apps & is really interfering with my productivity. Thougjts?
