Apple testing iOS 27.0.1 as iPhone 18 Pro Face ID reboot fix nears
Apple is testing iOS 27.0.1 for iPhone, with MacRumors reporting the same activity. Apple says a software update due early next week will fix a Face ID-related reboot issue on some iPhone 18 Pro and Pro Max units.
iOS 27.0.1 began surfacing in 9to5Mac analytics a few days ago, and MacRumors has reported the same activity. The update is likely to focus on bug fixes and performance improvements. Apple has not confirmed that iOS 27.0.1 is the software update it plans to release.
Apple told 9to5Mac that it will release a software update early next week to fix a problem that causes some iPhone 18 Pro and Pro Max units to restart after a failed Face ID attempt. 9to5Mac reported earlier this week that the issue occurs when a user tries to use Face ID to unlock an app such as Passwords and the authentication fails; the iPhone may then unexpectedly reboot.
The 9to5Mac author said he was unable to reproduce the problem on an iPhone 18 Pro or iPhone 18 Pro Max, but it affected a number of users. The report described it as a bug that can be fixed through software rather than a hardware fault.
It is likely but not confirmed that iOS 27.0.1 will address that problem. The update could also include fixes for other bugs affecting iOS 27 and the new iPhone 18 Pro hardware.
