Law enforcement officials in Detroit, Michigan suspect that iPhones running iOS 18 are causing other iPhones to spontaneously reboot, making them harder to unlock.
The alleged security feature in iOS 18 causes iPhones in forensic examination to restart when disconnected from a cellular network.
The rebooting makes it more difficult to unlock the devices using brute force methods.
Further testing and research is being conducted to understand the specific conditions that trigger the reboots.
