I can see lines under my S6 Edge+ in direct sunlight, and no its not the grid, and the lines are not all over the screen, I have one long one down the left side of the screen and some smaller ones on the right but not really anything in the middle of the screen. I can't really describe the colour of the lines but I'd say maybe they're white. It's really weird because I can only see them in sunlight, in any other lighting they're invisible, and when I say invisible I actually mean that. I have tried to spot them in any other lighting but I just can't. Is this normal? I found a post with someone with a similar issue but I'm not sure if it's the exact same thing.
