It's a good feature. A similar feature just got added to Android, too. If the phone loses network, it locks. If the accelerometer thinks that the phone has been snatched from your hand, it locks.

Btw, is there a way to set Android to automatically reboot at a fixed time? That'd only cost like 20 seconds more to unlock in the morning but reduce the chance of 3-letter-agencies being able to extract the content in AFU state.

  I can't find anything built into my Pixel, but it seems that Samsung and others offer it, or otherwise third party apps: https://www.reddit.com/r/androidapps/comments/1cscmu8/app_that_can_reboot_the_phone_on_a_schedule/ https://www.reddit.com/r/androidapps/comments/1cscmu8/app_th...

  Looks like Samsung can do it (though they offer it as advice to keep their buggy OS working, or to "to prevent it from slowing down or freezing" as they themselves put it): https://www.samsung.com/ph/support/mobile-devices/restart-your-galaxy-phone-regularly-to-prevent-it-from-slowing-down-or-freezing/ https://www.samsung.com/ph/support/mobile-devices/restart-yo... My Xiaomi phone had a feature where it would boot the phone shortly before any alarms would go off, so you could shut it down before bed and barely drain the battery in the mean time. Still required manual shutdowns, though.

  I'd be fine with this, EXCEPT: 1) Keep the alarm data in an insecure location so that app can work before login. (A read only cache is fine) 2) Let me _choose_ if some other apps can live in the insecure storage partition too. E.G. Google Voice comes to mind along with any basic carrier integration stuff you'd rather just have even on a fully locked phone. (Why GV in unlocked? It interacts with the insecure phone network anyway, so that's not exactly holding much back. Maybe make message history harder to get to with a still locked device.)

    Apps can already choose to place some data in pre-unlock or post-unlock storage, so your alarm or google voice should be unaffected.

  GrapheneOS has a feature to auto-reboot the device if it hasn't been unlocked in X hours. Set it sufficiently low, and it's a pretty good option to ensure keys are evicted and if you use a SIM pin, it's even better.
  - kuschku 2y ago
    That'd be exactly what I need. Sadly GrapheneOS is only available on recent Pixel devices. I know I'm probably the only one that still cares about these features, but I won't buy a phone that requires me to hot-glue a USB dock to it just to get 3.5mm and microSD if I can simply buy a Sony instead :/

There's a difference between locking a phone and entering Before First Unlock state. After a reboot and before authentication the credentials stored on a phone are locked down much more securely, to the point (most) apps can't even start in the background. Locking and disabling biometrics are good ways to add a quick layer of protection, but rebooting makes it incredibly difficult for exploit kits and other hacking tools to dump the contents of a phone's storage. I'm thinking this may just be a bug (how often does a real world iPhone get zero available networks of any kind? Probably not enough for that use case to be tested thoroughly for days) but with how hard law enforcement is panicking about this, maybe it should be a feature. If they care this much, I don't think their expensive hacking subscription they've bought is working anymore, so it's probably working around some pretty bad vulnerabilities in iOS.

  For me iPhone looses all connectivity on a daily basis. No cellular signals are available in the underground parking lot that I use.

> If the phone loses network, it locks. Am I the last person who regularly experinces dead zones, or does this sound crazy? There's no need to lock the phone just because I'm on the highway at this one spot on the way out of town.

  It's a minor inconvenience to reenter your PIN, and it's optional and disabled by default. Seems harmless.
