The screen is amazing on my iPhone 4, but I'd like to tweak the contrast and color settings because it's giving off a greenish hue in blue hued pictures. The contrast is a bit lighter than my sister's and the colors pop a little more on hers. Do I have to exchange it or is there a way to change this? Or even recalibrate the screen?
