A number of iPhone 18 Pro users are reportedly running into an unexpected issue with their devices, where using Face ID triggers an immediate system reboot. The glitch disrupts standard biometric authentication, causing the smartphone to restart unexpectedly.
While the exact root cause has not been officially confirmed, early indications suggest the problem interferes with normal lock screen access and authentication prompts. It remains unclear how widespread the glitch is across the global user base or whether it affects other models in the lineup.
Issues tied to biometric security and unexpected restarts are typically addressed through rapid software updates. In the meantime, affected users are waiting on a permanent patch or official guidance to resolve the recurring crashes.
