iPhone 18 Pro Face ID bug causes crashes, freezes for some users

Apple's redesigned Face ID system is triggering system reboots on certain iPhone 18 Pro models running iOS 27.

What to know

  • iPhone 18 Pro owners report Face ID failures causing system freezes and reboots, primarily when unlocking protected apps with biometric authentication.
  • 9to5Mac has reproduced the bug on a European model; the scope of the problem is unclear as not all users are affected.
  • The issue may be related to Apple's hardware redesign moving the infrared camera under the display, but is likely fixable via iOS 27 software update.

“Apple moved Face ID's infrared camera underneath the top-left corner of the display on the iPhone 18 Pro models to achieve a smaller Dynamic Island on the devices.”

    MacRumors reports Face ID issues across multiple categories

    MacRumors documents reports from Reddit and forum members experiencing three distinct Face ID problems: app unlock failures that freeze and reboot devices, 'Face ID is Not Available' setup errors, and the device ignoring the 'Require Attention for Face ID' setting.

    “It is unclear how widespread this problem is, but it can be hit or miss and not all users are affected.”

    9to5Mac reproduces Face ID bug triggering system crashes

    9to5Mac confirms a software glitch in iOS 27 where Face ID authentication failures on protected apps cause the device to freeze and reboot. The outlet reproduces the bug by failing Face ID authentication and tapping 'Try Face ID Again' on a European iPhone 18 Pro model.

    “If you are afflicted by the bug, the phone will lock up and stop responding to all touch input. After a few seconds, the phone panics and reboots back to the lock screen.”
