I am one of the many unfortunate ones to have the screen with the checkerboard pattern on their iPhone screen. In every image on our screens, you can always still see the faint grid in the background. However, I have noticed that sometimes, the grid changes its pattern. For example, look at the empty black space in the main menu. It shows the regular up-down, left-right pattern. Now, look around the edges of the top twelve icons and notice a pattern with lines of the dots going in a diagonal direction all closer together. Could this mean that the problem is software related? If not, could this mean anything at all?
