Whilst the screen on my 7 seems fairly even I've noticed that against a mid-coloured background (like when you drag down notifications) the right hand edge of the screen is uneven and you can pick out a series of darker rectangles seperated by brighter patches down the edge of the screen. It doesn't seem like regular backlight bleed as there's nothing apparent on a black background and you can't see it at all on a white bacground. I'm not sure whether to try and live with it or whether it'll get worse over time like the dark top corner on my 6. I haven't seen any other complaints of backlight bleed (unusual as normally there's loads of screen issues on launch models) so don't know if this is a one off and worth sacrificing a potentially ok phone for or not?!
