I tried slapping my phone, I reset my phone, and then slapping my iPhone 13 Pro Max, I totally turned off my camera, I cleaned (w/eye glass cleaner and dry, lent free cloth) my iPhone, I took off the clear protector, I removed my rubber case (which doesn’t obstruct the face of the camera or any part of the screen, I also update every time I see my “Settings” indicate such (currently iOS 17.5.1). I tried everything suggested in this support group over & over.
HOWEVER, after trying everything multiple times I took off my glasses, & tried one last hard “knuckle” knock (mostly out of anger) while looking at the “lower iPhone” glaring at me and voila! I was able to complete the Face ID. BUT, the second I put my glasses on, I got the FACE NOT RECOGNIZED again.
WHEN WILL THIS FRUSTRATING, RIDICULOUS, & irritating error be fixed? I venture to further say it’s NOT just the iPhone 13, 13 pro, nor 13 pro max.
