Hi, Im curious on how apple can actually tell if your screen has been replaced if there is some hidden apple serial number or something like that (for iphone)
 
If I'm not wrong, there is this QR code that they scan on the back of the display when they open up your phone to check for any unauthorized modification/repair.

Chances are your warranty is voided when it's repaired by a third party
