Hi there, This is weird. I've noticed this only really since I got iOS7 (though this was more than a month ago as I used the betas). There appears to be some kind of discolouration around the edges of my iPhone's screen. Take the status bar for example - in the messages app, the colour of the white of the status bar is slightly different to what is just underneath. And on the edges of the screen, there is a strip of about status-bar height that is slightly discoloured to the rest of the white on the screen. At first I thought this was meant to be, part of Apple's blur effects. But when I saw the outline appear around the whole edge of the screen, even on a blank white image in the photos app, I was confused. The best way to describe the colour is a sort of slightly green hue. It might not be noticeable straight away, but once you see it you definitely know it's there. Does anyone have any ideas?
