I noticed when I was looking at my phone from the bottom at maybe 70 degrees I was able to notice diagonal lines going at maybe 20 degrees across the whole screen. You notice it most on light colors. This was a huge problem on all the HTC Ones and something I haven't seen since and I just noticed it last night on my iPhone 7. As an EXAMPLE, they sorta look like the diagonal lines in this icon, but across the entire screen: Anyone else? (Please don't say you don't have it because you haven't noticed. You have to first look very carefully with high screen brightness in a dark environment, something you'd do when watching videos).
