Reports describe several Face ID problems on early iPhone 18 Pro models
Users have reported freezes and restarts after failed authentication, setup errors, and issues with the Require Attention setting; the cause is still unclear.
TLDR
Some early iPhone 18 Pro and Pro Max users are reporting several Face ID problems, according to 9to5Mac and MacRumors. The reports include failed authentication followed by freezes and restarts, a "Face ID is Not Available" message during setup, and behavior that appears to ignore the Require Attention setting. 9to5Mac reproduced the freeze-and-reboot behavior on one European iPhone 18 Pro. It is unclear how widespread the issues are or whether they relate to Apple's new under-display infrared camera.
