Is Your iPhone on the Latest Software?
Sometimes simply updating your iPhone to the latest software version will remedy the issue of Face ID, Home Button, Camera and other function.
All you need to do is go to Settings > General > Software Update to check for and install any available updates.
Try a Hard Reset
If your iPhone is already on the latest software version, give a hard reset, or force restart, a try. To make it happen, quickly press and release the Volume Up button, then quickly press and release the Volume Down button. After that, press and hold the Side button on the right side of your phone. Keep pressing the button down (be sure to ignore the Power Off slider!) until the Apple logo appears, then release the Side button and wait for your iPhone to restart.
