Law enforcement warns that securely stored iPhones awaiting forensic examination are mysteriously rebooting, making them harder to unlock.
The reboot causes the iPhones to lose their "After First Unlock" (AFU) state, making unlocking more difficult for law enforcement.
The issue was documented by law enforcement officials in Detroit, who suspect it is due to a new security feature in iOS 18, causing iPhones to reboot when disconnected from cellular networks.
Forensics labs are advised to isolate AFU devices from iOS 18 devices and check if any AFU devices have already rebooted.
