Hey guys, I just noticed today there's yellow edges around my 5s screen. Should be the infamous glue issue or others. Few days ago, if I'm not mistaken, there no problem.

Or is it because I have just updated to iOS 9.2.1 from 8.4? As I try to recall, I don't think there is this problem during my period using 8.4.

Anyone of you is facing this problem too? So how did you deal with it? As for me, it's okay using it, just that when you're under settings, messages, or any white background, the yellow edges appear and it seems to annoy me.

Is there any way to solve this issue? Warranty is also over. Thanks for reading.
