Has anyone noticed the black vertical lines that appear on a complete black picture in the new control center ?! Note this is only peculiar to iOS 11.0.3
Steps to see the bug
1. Go over a complete black picture while your phone screen brightness is turned on to full . N.B. It has to be a complete black picture (#000 color hex code)
2. Then swipe up on that black picture the control center
3. You'll see heavy black or gray vertical lines at the edges of your screen as seen in the screenshot attached to this thread
4. Take a screenshot to see properly !
