"There is an apparently new iOS 18 security feature that reboots iPhones that haven’t been unlocked in a few days, frustrating police by making it harder to break into suspects’ iPhones
…
Apple added “inactivity reboot” code in iOS 18.1 that triggers iPhones to restart after they’ve been locked for four days"
GrapheneOS supports it.
That’s super cool! I guess I should’ve expected that. Still unfortunately means you need to be a Pixel owner and to have installed a non-default OS, which is an extreme minority of Android users – compared to iOS 18.1 blanketing every 12th-or-later-gen iPhone.
Yeah… I hope that it becomes a standard part of Android one day.
