Gezixuan reported on November 10 that, according to 404 Media, earlier this week, the police found a strange phenomenon in the seized iPhone devices - these devices would restart themselves without operation. At that time, the cause of the incident was not clear. However, experts are now beginning to unravel the mystery.

Gezixuan noticed that the unexpected restart of these iPhones was not a bug, but a new feature. Dr. Jiska Classen of the Hasso Plattner Institute said Apple has added an "inactive restart" feature to iOS 18.1. Classen posted a screenshot of the code on social media to further confirm this.

In addition, Christopher Vance, an expert from Magnet Forensics, revealed in a private chat group of law enforcement and forensics experts that they found a code that triggered the inactive timer, explaining: "When the timer goes to zero, the device restarts and the status changes from AFU (Authorized File Access) to BFU (Unauthorized File Access). ”

This feature is designed to prevent thieves from easily accessing user data on locked devices. But for now, it seems that this feature has also caused some inconvenience to law enforcement.
