Apple's newest iPhone has a Face ID problem, and today's patch is the first attempt to fix it.
Apple released iOS 27.0.1 today, two weeks after iOS 27 launched, along with matching iPadOS 27.0.1, visionOS 27.0.1, and iOS/iPadOS 26.7.1 updates for phones still on last year's software. The fix targets iPhone 18 Pro and Pro Max owners who reported Face ID failing to unlock apps, freezing the phone, and triggering an unexpected reboot. Some users also hit a "Face ID is Not Available" message during setup, or found the Require Attention setting misbehaving. The same update also patches a color artifact that appeared in 2x photos shot at f/1.48 under certain lighting.
This is the first real hiccup for the iPhone 18 Pro's marquee hardware change: an infrared Face ID camera hidden under the display for the first time, rather than sitting in a notch or Dynamic Island cutout. Apple has not said whether the bug lives in software or in that new sensor placement, only that it expected a software fix to work. A reboot-inducing authentication failure on a two-week-old flagship is the kind of bug that gets fixed fast and remembered slowly.
Apple says the crashes should stop now, but a first under-display Face ID camera and a first public Face ID bug report arriving in the same product cycle is not a coincidence worth glossing over.
