Apple quietly introduced code into iOS 18.1 which reboots the device if it has not been unlocked for a period of time, reverting it to a state which improves the security of iPhones overall and is making it harder for police to break into the devices, according to multiple iPhone security experts.

On Thursday, 404 Media reported that law enforcement officials were freaking out that iPhones which had been stored for examination were mysteriously rebooting themselves. At the time the cause was unclear, with the officials only able to speculate why they were being locked out of the devices. Now a day later, the potential reason why is coming into view.

“Apple indeed added a feature called ‘inactivity reboot’ in iOS 18.1.,” Dr.-Ing. Jiska Classen, a research group leader at the Hasso Plattner Institute, tweeted after 404 Media published on Thursday along with screenshots that they presented as the relevant pieces of code.

  • You can use GrapheneOS, a security-focused version of Android which includes auto-reboot, timers that automatically turn off Wi-Fi and Bluetooth after you don’t use them for a certain period of time, a duress PIN/Password that wipes all the data from your device after it’s entered, as well as many other incredibly useful features.

    It’s fully hardened from the ground up, including the Linux kernel, C library, memory allocator, SELinux policies, default firewall rules, and other vital system components.

      graphene is ONLY for select Google pixel phones though. I wish this was made much clearer by the team and advocates.

      its a real shame because pixels, although big in the USA are typically a minority of most android ecosystems elsewhere, and bootloader hijinks keep some perfectly capable phones from being easy to switch over to, even if they were supported.

      Even on samsungs, which are much better for flashing than they used to be - my options on a year old flagship for a decent ROM are pathetic compared to the old days.

      so I would really love to use graphene, and go back to an open source ROM without crap on it, but pixels are such a bottom tier phone for their price in a lot of places, as much as I really really want the project go gain traction for their transparency and objectives.
