I have a problem with my I phone in the face ID , I can’t setting face ID ?!

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. Genius Bar Reservation and Apple Support Options - Apple
