Face ID is not available after drop
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.
