I bought an ipad 4 a few weeks back and the edges (top and bottom) had a blue tint to them when on a white screen. Considering the main reason i bought an ipad was to read comics on it, meaning the screen would be white around the edges 90% of the time, i decided to return it. The replacement i got was the same. So i called Apple and the guy spoke to his team leader and the team leader said he had heard of the issue before, but it was not normal and i should replace it. The replacement.... the same. I am wondering is this normal? if someone can put on a white background and look at the edges i would really appreciate it, to see if there is a blue tint. I am thinking maybe because i got my ipad and the replacements from John Lewis store and not Apple store maybe thy have older stock.
