I noticed at the top of my iPhone 6 there's a dark shadow more like a dark band. I have a genius appointment tomorrow so that they could have a look and hopefully swap it out for me for another one, however I have read many people on here who have had the same exact issue with there iPhone 6 so I'm not sure if it's even worth changing it or not, have any of you have the same issue and then swapped out your phone and gotten one with the perfect screen.
