Most of the area of my iPhone 5 display now has a very faint pink tint. There is a thin white border all around. I did a search and it seems like this is a widespread problem even with replacement devices :-( So far the usability of the device is unaffected. My question is: how much more pink does the screen get over time? I can live with this, as long as the screen doesn't become like the T-Mobile logo and pink everything out.
