Apple has released iOS 27.0.1, an update aimed primarily at resolving bugs affecting its newest smartphones. The software began rolling out to users on Monday. Owners of the iPhone 18 Pro and iPhone 18 Pro Max had reported several problems, most notably devices restarting without warning after Face ID failed to authenticate.
The Face ID issue drew enough attention that some customers had their devices replaced by Apple, only to find the problem persisted. Apple confirmed in September to 9to5Mac that the new iPhones may restart unexpectedly when Face ID fails to authenticate. The company also told 9to5Mac it would release an update to address the issue, and iOS 27.0.1 delivers that fix.
The update addresses more than the restart bug. It also resolves a color artifact that appeared in photos taken on the iPhone 18 Pro at the 2x zoom level. In addition, it fixes a glitch that caused devices to become unresponsive when users opened the Notification Center and Control Center at the same time. That issue did not cause lasting damage and could be cleared with a forced reboot, but it was potentially annoying for users who did not know their phones would resume operation after restarting.
Not all iPhone owners will see iOS 27.0.1. Those still running iOS 26 may instead be offered iOS 26.7, an update specific to the iPhone 17 and earlier models. That release provides only security patches for users who do not want to install iOS 27 yet.
Skipping iOS 27 means forgoing new features such as Siri AI and Liquid Glass tweaks. Users who want to move from iOS 26 to iOS 27 can tap the iOS 27.0.1 banner on the Software Update screen, which will skip the iOS 26.7 update instead.
The rollout follows a wave of complaints from iPhone 18 Pro and iPhone 18 Pro Max owners after the devices launched. Reports of spontaneous restarts tied to Face ID authentication failures surfaced among users, prompting Apple to acknowledge the problem publicly. With iOS 27.0.1 now available, the company is addressing those complaints while continuing to offer security support to older hardware through the separate iOS 26.7 release.
