I haven't taken too many pictures using flash but my dad just got a 4S so I figured I'd compare mine with his. My phone is white, his is black. Here is how my picture came out: And here is his: At first I thought it would be the screen protector on the back of my phone so I took it off and the pictures still came out with the white tint. I've restored numerous times trying to get my battery to get better and it's pretty good now, usually getting 6 hours of usage and at least a day of standby, and my dad and co-worker both just got their 4S and they have the yellow tinted screen, so I'm hesitant to want to go to Apple for a replacement. I'm assuming there is nothing I can do other than replace it right? And I'm not crazy, that picture is white right?
