Iphone 5 screen becomes discolored and freezes?
Recently, my iphone's screen has started becoming discolored- the images change to purple and green hues, then the screen becomes unresponsive, and fades to black. Actually it looks like this person had the same issue as me:
This only happens occassionally, and I noticed that it happened more when my phone heated up, like if I was using a high powered app. But now I can't recreate the problem, and I already ordered a new iphone under my apple warranty! I KNOW the issue is there, I even recorded a video of it for proof. But I don't want to send this back to apple and have them charge me the $800 for the new phone, because they see nothing wrong with it... how does apple usually handle issues like this under warranties?
iPhone 5, iOS 7.1
