tl;dr: Magnet Forensics, maker of the GrayKey phone-cracking tool used by law enforcement, has developed new products ("GrayKey Preserve" and an "Evidence Preservation Mode") that bypass Apple's inactivity reboot feature. That iOS feature, introduced in late 2024, automatically reboots iPhones after 72 hours of being locked, reverting them to a state that's harder to crack. The workaround helps police preserve seized devices in a more accessible state while waiting for warrants or working through backlogs.
