Face id not working
My Face ID Has Been Disabled
A problem was detected with the TrueDepth
camera. Face ID has been disabled. How to fix it please help me
iPhone 13, iOS 18
It may be a hardware issue, but see if anything here helps:
If Face ID isn't working on your iPhone or iPad Pro - Apple Support
If not, then you'll need to contact Apple Support or take the iPhone to authorized Apple service for further assistance.
Regards.
