Guillaume On iOS, the phone restarts when you change location and you do not use it, there is no timer
Is it possible to provide a source supporting that claim?
Lots of sources say it is exactly a timer, such as: https://appleinsider.com/articles/24/11/09/iphones-on-ios-181-will-automatically-reboot-and-lock-down-after-being-idle-for-a-while
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?
phone-company I have an iPhone and it asks me for my code after 4 hours without being used
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.
Guillaume this seems interesting. Let's see what other user reports.
This is one of the funniest things I have read in a very long time.
treenutz68 Neither does he ask me for my code when I wake up, I think he detects when I change places
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.
phone-company A bag is not enough for radio waves, the thickness of your cage must be 3cm. Take your iPhone, travel 30km by car and tell us if it restarts
Guillaume
A bag is enough, test some you will see they work.
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
NetRunner88 Yeah, the skin depth in metal at cell frequencies is tiny, no need for 3cm shielding. It is much more about having proper RF tight seals on the container. Source: https://www.mattblaze.org/blog/faraday/
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.
For me 4 hours works perfect
Eight hours works for me.
