Apple has confirmed a software update arriving early next week will resolve a glitch causing iPhone 18 Pro and Pro Max devices to freeze and restart unexpectedly following failed Face ID scans. The company states the issue stems from a software flaw rather than hardware damage, sparing early adopters from unnecessary handset replacements.
The latest flagship iPhones have barely settled into owners’ hands following their release, yet early adopters have encountered a frustrating software malfunction. Rather than unlocking smoothly, some devices freeze entirely and become unresponsive to touch inputs after a biometric authentication fails inside protected applications. Some owners already swapped phones at Apple stores, assuming a hardware fault, while a Reddit user stated the company considered their iPhone faulty and issued a replacement. The resulting instability eventually forces an unprompted reboot.
How the Face ID Bug Triggers Unexpected Restarts
The glitch does not typically strike on the standard lock screen. Instead, users running iOS 27 report that complications emerge when biometric scans fail inside specific apps that require individual security measures, such as the Passwords application or tools locked within the Wallet ecosystem—with a Reddit user experiencing crashes upon opening the Wallet app. When authentication fails, the screen displays a prompt to try scanning again. Attempting a second scan on affected handsets is where the malfunction escalates, locking up the touch interface before the operating system triggers a hard reset a few seconds later.
Subsequent checks of device diagnostic logs reveal a panic-log entry generated when the kernel encounters a critical failure. While such logs can theoretically point toward failing hardware sensors or mainboards, Apple has acknowledged to 9to5Mac that the core issue is software-related. For users who rushed to retail locations fearing a defective component, the confirmation brings welcome reassurance that handset swaps are unnecessary.
Interim Workarounds While Awaiting the Patch
Until the officially patched firmware arrives, owners are advised to avoid repeatedly tapping Try Face ID Again
after a failed scan. Utilizing a passcode serves as a stable alternative for opening protected applications without risking a system freeze. For devices that do lock up entirely, users can execute a manual hard reboot by quickly pressing and releasing the volume up button, followed by the volume down button, and finally holding down the side button until the Apple logo appears.
The timing of the bug aligns closely with hardware shifts built into the iPhone 18 Pro and iPhone 18 Pro Max, which feature a redesigned sensor layout. Apple introduced the two Pro models on September 18 with iOS 27, featuring a newly designed Face ID system within the framework of a reduced Dynamic Island where the infrared camera sits under the display. Although speculation naturally surfaced regarding whether the novel screen-and-camera architecture contributed to the bug, neither the company nor diagnostic logs have tied the reboot glitch to the hardware changes.
Launch Demand and Accompanying Display Reports
Concurrently, a smaller volume of users have shared isolated complaints concerning vertical green, pink, and red display lines. While these visual glitches have revived legacy community discussions surrounding OLED and LTPO+ panels sourced from manufacturers like Samsung Display, market observers note no current evidence indicating that the display anomalies affect a significant share of manufactured units or stem from a unified hardware defect.
Firmware Deployment Timeline
Apple has assured customers that the Face ID reboot malfunction will be addressed via a dedicated software patch scheduled to roll out early next week—with reports noting the roll out is planned for the week beginning September 28. Web analytics have already spotted references to upcoming builds such as iOS 27.0.1, which will likely house the fix alongside routine optimizations. The company deployed a similar patch via watchOS 27.0.1 to correct unforced restart bugs on the Apple Watch Series 12 and Apple Watch Ultra 4, demonstrating a rapid deployment cycle for post-launch firmware adjustments.
