My Face ID is not working on my iPhone

If your Face ID is not working, see this, If Face ID isn't working on your iPhone or iPad Pro - Apple Support and this If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support. If neither help, then use the Get Support link at the top of the page here to contact Apple Support for service, or make a Genius Bar appointment at your nearest Apple Store. 

Try the following:

▷ Update your iPhone. 📲

If that didn’t help, then try a Hard Reset:

1. Press volume up (quickly)
2. Press volume down (quickly)
3. Press and hold the power button until the Apple logo ( ) appears

If that didn’t work, it could be a hardware issue. ⚠️
