Changed Screens, Face ID not working..
So i work at a repair shop and got given an iPhone X with a damaged screen, the face ID still worked on it fine though.
I also have my iPhone X with a perfect screen, Face ID working also..
Decided to swap screens because i was curious to see the inside and work on them.
Swapped screens and neither Face ID work, i straight swapped them without removing anything from either screens.
I Follow some google steps by resetting settings etc on the originally broken phone because mine is jailbroken but still not working. I move the screens back to the original phones and they both work fine with Face ID..
What causes this? Am i missing something?
Is this a good question?
