Ipad air 16gb space grey, yellow hue in bottom left corner in portrait. Strongest in that corner but dissipates as it goes up the left hand side and also to the right disappearing at about the home button. It is noticeable on white pages and when bringing up the keyboard. The keys on the left have the yellow tint while the right side is the normal cooler hue.
Had this with the ipad 3 (yellow and bad light leak).
It's like a bad dream relived all over again!
