Hello i have a problem regarding the Face ID of the iPhone XS Max. After dropping my phone on it’s back the glass on the back shattered. But unfortunately since then the Face ID also doesn’t work anymore despite the fact that the front panel is in perfect condition. The portrait mode with the front camera doesn’t work too. It doesn’t recognize my face properly. my question is: Which part has a failure and how can I manage to bring the Face ID back to life again.

Face ID will only work if apple does a screen replacement on the phone. Chances are the flex for the FaceID sensor module is torn and will cause it to not work. Replacing it will not fix the problem as it requires apple to pair the part with the board which sucks.
