He said he got it last march, way past the return window. Even if he brings it back, how is he gonna prove to them that he didn’t get the camera fixed/replaced? I would actually suggest taking it to the Apple Store and see what the employee say

Screen protectors are at the point where it still feels very close to the actual screen it’s protecting. I honestly don’t see why not use one.

Uhhh… On paper, I would say they won’t service it because they’re technically dealing with a non-genuine apple part/service that was done to your phone. In reality, they might just let it slide(?) Never know until u try
