Is anyone else's 820 doing this? My unit is over the year old mark and has been showing it for a month or two. 1/4in around the edge of the screen you can see pixels and the screen is faded. When looking straight on at the screen it's not as noticeable. Any angle and the you can see this quite badly. Especially in the loading screen when the screen is all black, the middle is black and the edge is blueish/gray.
