Yes I have. I'm on my second phone now. The first one the main screen became darker than the rest. You could easily see a line where the notification bar is supposed to be and in the middle of the edge screen. Look awful. Checked out someone else I know with same phone and his was doing it too
I'm not sure which version of Lollipop I got 5.0.0 or 5.0.1 . All i know is now my Samsung keyboard says it's not responding. And now in the last 5 or 5 days, it locks up while I'm in Facebook
