I just noticed that my new iPad 3 has this problem: the left top corner of the screen is a little bit darker than the right top corner. Actually all the left side along edge is a bit darker. When I open the Safari, I can see the color of the search bar at both ends are not consistent. But when I rotate to the right, they seem to be the same, which can prove the the color is not consistent from life to right in the portrait mode. Is anyone seeing the same issue? I think I make take it back to the apple store to check. Thanks in advance!
