Why my Face ID not working again??

Hello,

Apple has several documents helping you with Face ID.

This document is specific to seeing a 'disabled' Face ID alert, and explains what to do when you see that notice. --> If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support

If you don't see a 'disabled' message but do have general 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.

You can follow the steps for restoring Face ID in the document that has already been linked in a previous post in this thread.

The third step in that document involves sending your iPhone to Apple or an authorized service center for repair. Once you have done that, let us know if you still have problems with Face ID.

My Face ID is not working right now can I do right now please
