Apple has confirmed that a software update is coming to fix a Face ID-related problem affecting some iPhone 18 Pro and iPhone 18 Pro Max users. The issue can cause the phone to freeze and restart after a failed Face ID authentication attempt.
Apple says the fix is expected early next week. The company has not officially confirmed the version number, but iOS 27.0.1 is currently the likely update that could include the fix.
Face ID failure can cause the iPhone to restart
The problem affects some iPhone 18 Pro and iPhone 18 Pro Max units when Face ID fails during authentication inside certain protected apps. In reported cases, the phone can become unresponsive before restarting on its own.
The issue is not reported to affect every iPhone 18 Pro or Pro Max. The number of affected devices is also not known.

Testing by 9to5Mac found that the problem could be reproduced when Face ID failed while trying to access protected content such as the Passwords app. The device could then stop responding to touch input and restart.
Apple confirms a software fix
Apple has confirmed that it is preparing a software update to address the problem. The update is expected to arrive early next week.
Apple has not yet provided the complete release notes or confirmed that the update will officially be called iOS 27.0.1. However, Apple is already testing iOS 27.0.1, making it the likely candidate for the upcoming fix.
The confirmation is also important because it indicates that affected users do not necessarily need to assume their iPhone has a hardware failure.
Why iPhone 18 Pro Face ID is important
The iPhone 18 Pro series introduced changes to Apple’s Face ID system as part of the effort to make the Dynamic Island smaller. The infrared camera has been moved underneath the display area, allowing Apple to reduce the visible front cutout.
Apple has not said that this hardware redesign is responsible for the reported problem. The company is addressing the specific reboot issue through software.
What should iPhone 18 Pro users do?
If your iPhone 18 Pro or Pro Max is working normally, there is no need to replace the phone because of this specific issue. Users experiencing the Face ID-related restart should keep their device updated and install Apple’s official software fix when it becomes available.
It is also a good idea to keep an iPhone backup before installing major software updates. If a device continues restarting for reasons unrelated to Face ID, users should contact Apple Support for further diagnosis.
