iPhone 5 screen displays white color inconsistently
Couple months ago I started noticing that when displaying white color, my iPhone 5 is showing a much "cleaner" whites towards the edges as opposed to the majority of the screen, which gets a magenta tone added to it. Initially I could almost ignore it, but it has started to worry me lately as it bacame more noticeable.
I've tried taking a picture, but it was really hard to show the effect. I think the following image would demonstrate the issue in a better way:
The actual problem is not that severe as displayed above, and it only affects pure whites (grays look fine). Basically, a certain distance from the edge of the screen is much whiter than the majority of the screen, which is reddish. This issue is persistent accross applications / white boot-up screen. I've removed the screen protector to make sure it wasn't causing the effect.
Has anyone faced the same issue and what would be the best solution? Does this make a case for product replacement? My iPhone 5 is still under warranty.
Thanks in advance!
Sincerely,
