A frustrating rebooting glitch has emerged in Apple's latest flagship devices, the iPhone 18 Pro and the iPhone 18 Pro Max. According to user reports, when Face ID authentication fails on these handsets, the screen suddenly freezes, touch input stops responding, and the phone automatically restarts after a few seconds.
While this technical snag does not impact every single user, numerous cases have surfaced across social media platforms and reader reports. Acknowledging the glitch, Apple has confirmed that a dedicated software fix is currently in development and is expected to roll out early next week to resolve the unexpected reboots.
How Face ID Failures Trigger Freezes
According to detailed findings, the issue specifically manifests when an individual attempts to open a secure application using Face ID and the authentication process fails. Technicians and reviewers have replicated the behavior on the iPhone 18 Pro to understand the root cause.
During testing, blocking the Face ID sensor resulted in a failed authentication prompt, immediately followed by the phone locking up, ignoring touch commands, and executing a hard reboot moments later. Review of the device settings under the iPhone Analytics section revealed a corresponding panic log detailing the abrupt shutdown.
Investigating the New Face ID Design and Software Bug
The iPhone 18 Pro lineup features a heavily redesigned Face ID architecture. Its infrared camera has been relocated directly behind the display near the status bar clock, an alteration that shrinks the visible Dynamic Island by roughly 25 percent compared to previous generations.
Despite this major hardware layout shift, no concrete evidence currently points to the physical components as the cause of the rebooting loop. Initial assessments and reports strongly suggest that the glitch stems from a software-level bug rather than a structural hardware defect.
A few early adopters initially mistook the software hiccup for a hardware failure and sought device replacements at retail stores. However, with Apple confirming an upcoming software patch, users experiencing this specific bug have been advised that hardware replacements are unnecessary.
While the company has not officially specified which exact software version will bundle the fix, testing activity surrounding iOS 27.0.1 has been observed, indicating the upcoming release is geared toward patching such stability bugs.
In a related software rollout, Apple has also released watchOS 27.0.1 specifically to address random restarting issues previously reported by owners of the Apple Watch Series 12 and Apple Watch Ultra 4.
