Anyone have this issue? My display is slightly darker (and yellower) on the top left corner. I didn't notice it at first but now I notice it I can't unsee it anymore. I come from a country without Apple Genius Bar and the service of the resellers here are terrible. It would take a month or two to get my phone replaced. Worse still, I checked the display units at the resellers and they have the same issue too. So I don't know if I should play the lottery or what.. Now. Should I take it to exchange now or should I wait a couple of months until this issue is resolved Every other thing about this phone is perfect.
