  • Police Freak Out at iPhones Mysteriously Rebooting Themselves, Locking Cops Out

Here's another story about Apple's new feature:
https://www.neowin.net/news/experts-reveal-why-iphones-are-suddenly-rebooting-themselves-leaving-police-stumped/

So looks like seizures of IPhones would now be prioritized for examination. GrapheneOS's has a superior implementation in that it allows users to choose the trigger time assuming Apple's is static.

It's nice to know that the GrapheneOS developers had the fore-site to add this wonderful feature many years ago, I'm sure Apple has never heard of GrapheneOS ;) wink.

Guillaume no, timer is 72 hours.
For example, mobile phones are placed in a Faraday case after being confiscated by the investigating authorities. This means that localisation via radio cells or GPS is not possible

This means that a timer expires which, according to our tests, is triggered after 72 hours without use

      Guillaume i didn't claim there is something to adapt on ios. I've mentioned in contrast to the implementation on ios currently, grapheneos gives you the liberty to set the time of inactiviy (i.e. timer) before reboot.

      On ios it seems the phone restarts after a period of inactivity. 'Under the hood' this means that the os keeps track of a given period between last unlock and a certain value where it decides to reboot. How would you deem this possible, if not implemented with a timer of some sort?

      I'm unaware that 'change location' is
      a requirement to trigger the reboot after a certain period of inactivity.
      I would love to learn more about that, would u mind providing a source on how you came to that conclusion?

        I've noticed my business iphone asking for the code more often recently as well. I haven't timed it, doesn't feel like its as short as 4 hours to me, since when I wake up in the morning it doesn't typically ask for the code.

            This is one of the funniest things I have read in a very long time.

            Guillaume i triyed it with a special farrady bag wie use for our Laptops and devives usualy... And no result after 4hours. AS i wrote after 72 hours the device reset .... Round about

                Also good to point out that asks for passcode != BFU. There should be some text saying “Touch ID requires your passcode when iPhone restarts.” Or something to the effect.

                If you are uncertain which Faraday bag works, go into your local supermarket, put a premium steak in the bag, and try to walk out with it. If you get a free dinner then you know what works. But if your next bunk mate is Harry the Hatchet Murderer, then strike that bag

                72 hours to reboot, that's an eternity...
                My GrapheneOS 6a is set at 2 hours.
                I have a 14 digit passcode and no fingerprint access. A rebooted phone from AFU to BFU makes no difference access wise to me.

                  geko I agree that 72 hours is unnecessarily long, but do you have any particular reason for setting it to 2 hours ? Or is it just that it works well for you ?
