After a camera repair my face unlock doesn't work
After repairing the camera, when trying to re-setup face unlock this message pops up and cancels the setup “Enrollment was not completed, certificate expired“
This might be stupid if you have not tried but if you have not go to settings and go to where it said password if you click on that and it will ask you for a passcode put that in and there is a button which said reset face id click on that and you can reset it.
The problem is that the camera module is tied to each board.
I can confirm this. Pucchaced an At&t pixel 4 on ebay that wasn't working. And another unlocked version with a broken screen. Now the damage to the screen was at the top close to the modules. So when doing the board swap I decided not to swap camera modules because the fear of having a damaged module. After swap face unlock work before reboot. After that it never worked on both phones. Had to swap over the camera modules to get face unlock. Works like a charm now..
