How come when all (even the display models) iPhone 4s are tilted to the right, the color hue is different than when the phone is tilted to the left? It's not a issue at all, just curious if any screen experts know this. Maybe its because of the retina display? You can still read fine during both tilts. When tilted to right the color is very very blue, tilted left its more white and yellow. edit. Heres how to tell, tilt your iPhone 4 left and then tilt it down while its still being tilted left. Same with right. You will see 2 different colors. I've tested over 100 iphones at the Apple stores in SF, Cupertino, mission viejo and one in Florida.
