The iPhone 18 Pro and Pro Max models have introduced a new smaller Face ID system, with the Infrared camera now hidden behind the screen near the status bar. However, a software glitch in the shipping release of iOS 27 may cause this component to malfunction. Users are reporting that their devices freeze and reboot after a failed Face ID attempt, particularly when trying to unlock protected apps like passwords or private Safari tabs.
The issue does not occur directly on the lock screen. To reproduce the problem, users should cover their face with their hand to simulate an authentication failure, then tap the "Try Face ID Again" button. If they are affected by the bug, the phone will freeze and restart. Apple support reportedly recommended a hardware swap, but this is likely a misdiagnosis.
A similar iOS 27 bug may also cause system reboots on any iPhone model, expected to be fixed with a forthcoming software patch. Apple has been contacted for comment on the Face ID issue.
