Thank you for sharing this video. I played it and I did not get any weird flickering, but I did notice that during the video where it says "this is true black" I did not get true black, but the borders or the side black bars were true black. If I made the video cover the entire screen, it does not show true black again and if I make it smaller, the borders turn true black. This gives me hope that this might be a software issue and I won't have to get a refund and try my luck on a different phone. Though I might have just gotten a pretty decent one.
