Hi This may sound like a bit of a thick statement but I got my iPhone last week, it's a week 31 build, it has a bit of a yellowish tint on the screen compared to my dads who get his launch week. When comparing both side by side, the display on his is a lot clearer than mine, I cannot see a single pixel. However on mine they are visible, not individual pixels but more like horizontal bands when changing the viewing angle. How is it possible to see them on one iPhone but not the other? Could it be a cheaper display, the yellow tint making them more visible or a fault?
