Face ID is designed to work when you hold your iPhone about 10-20 inches away from your face. If Face ID is not working on your iPhone, you may be holding it too close or too far away from your face.

How Do I Make Sure You're Holding My iPhone The Right Distance From My Face?

  1. Hold your arms straight out in front of you to make sure it's far enough away from your face.
  2. You may need to close and reopen the Settings app if Face ID failed the first couple of times.
