vertical 'prison bars' cover the iPhone 5s screen, everything is behind these bars so cannot access anything. Tried rebooting which does nothing, except sometimes I can access apps but without going through password page
I have an iPhone 5S. These bars appeared when I was using an app - Tinder - completely covered the screen and now my phone is inoperable. Anyone had the same experience? Reboot doesn't seem to work.
