Good day, sometimes when I unlock my phone the screen has a line in it. The top half is fine and the bottom looks weird. The color is faded then it corrects itself. I never got a screenshot of it but I was trying to watch something recently. I turned my phone to watch it full screen and as soon as I turned it half of the screen was black. The video continued to play as normal but I could only see half of it. What is causing this irregularity?
