iPhone 18 Pro Face ID Bug Causes System Crashes and Reboots for Some Users
Key points
- iPhone 18 Pro/Pro Max users report reboots after failed Face ID.
- Bug occurs when unlocking protected apps, not from lock screen.
- Issue is reproducible and likely a software glitch in iOS 27.
- Apple support reportedly suggested hardware swaps for some users.
Face ID Glitch Identified
A software glitch in iOS 27 is causing some iPhone 18 Pro and Pro Max devices to freeze and reboot. This issue specifically occurs after a failed Face ID authentication attempt, particularly when users try to unlock protected applications such as the Passwords app or private Safari tabs.
Reproduction Steps and Scope
The bug can be reproduced by intentionally failing a Face ID scan (e.g., by covering the face) and then tapping 'Try Face ID Again'. Affected devices will then lock up and reboot. The problem does not appear to affect all iPhone 18 Pro owners, and its full scope is currently unclear. It does not trigger directly from the lock screen.
Potential Software Fix
Despite some reports of Apple support recommending hardware replacements, the issue is likely a software bug. A similar iOS 27 bug causing system reboots on other iPhone models is also expected to be resolved via a software update. The new iPhone 18 Pro features a redesigned Face ID system with the infrared camera hidden behind the screen.
