My Face ID not working

Hello nabatoyo,

Apple has several documents helping you deal with Face ID issues.

This document explains what to do if you see a 'disabled' Face ID alert --> If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support

If you just have issues with Face ID not working properly, explore the list of things to try in this document: If Face ID isn't working on your iPhone or iPad Pro - Apple Support

If the first 8 don't solve the issue then use #9, contact Apple.

This is most likely a hardware issue. Please update your iPhone to the latest iOS version. If this is not working, please contact apple support to set up hardware service for your device.
