On Thursday 404 Media reported that police were freaking out about mysteriously rebooting iPhones. Now multiple experts have found that Apple introduced code that reboots locked phones after a period of time.

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.

      Foss OSes… GrapheneOS for sure but I also saw enjoyers stating calyxOS will also do the trick.

      Sure, F-Droid. It’s an app store that not only is exclusively foss, they only host things they can build from source in house and seem to have a decent review process - they tag anything from ads to integration with paid services, and those features are often buried so it seems like they’re pretty militant about it

      It comes with all the drawbacks that entails, but I generally check there first myself
