Why won't Face ID work?
I replaced the screen on my iPhone XS Max. Everything went back together and worked perfectly. Until… about 4 days later the iPhone shut off unexpectedly and when I turned it back on I was given the notification that “Face ID is not available”. I have read that if Face ID sensor cable was damaged it would cause Face ID to become unavailable. If this is the case, why did it work for a few days and suddenly stop? Someone please help!
