Jokes on them, my S22 Ultra restarts in it’s own. Even when I don’t want it to.
finaly the nsa doesn’t do something stupid
I’d love to see your list of “stupid” things… not immoral, vicious, incendiary, criminal, etc…but stupid. None of those things is stupid if they are also your fundamental mandate.

You may have missed the joke
You do it because it makes an attacker’s life harder because now I have to find two bugs instead of one.
The entire boot chain of the phone up to the apps you run are verified successively by the component that loads it. A digital signature helps ensure that only trustworthy code ever runs. A bug must be found to bypass these checks to load malware code. For example, a bug in the image code in a web browser might cause loading of code that isn’t checked. This way the malware gets smuggled onto the phone.
This means that if you get hacked via one bug and malware is loaded, the attacker has to work harder to solve the problem of how do I convince the phone to load it again at boot because the code it’s made of isn’t going to be approved code. When you reboot, you are effectively forcing a validation that all the code you have running is authentic, which would exclude the malware. Trick me once sure, can you survive a full pat down? Probably not. It’ll get caught.
Unless I have a second bug to fool the normal code loading systems too, the malware can’t run. You have to go back and trigger the first bug again somehow, which places more strain on the attacker.
Exactly, as you already explained in detail this is primarily for security.
GrapheneOS has a feature to set a time after which the phone reboots in case there was no unlock. So in case a bad actor gets your phone they only have that time with a running system after the first unlock. However, if you use it normally, and unlock it in regular intervals it does not auto-reboot. This is especially neat if your threat level is not “investigative journalist” or “political activist on the run”, because then you can set the time to a longer interval and the phone does not reboot every night when you are asleep which also leads to the SIM card being locked and nobody being able to call you…
I remember this feature, and I wish it was a standard Android feature. It sounds like it would be trivial to implement and could be completely optional.
I wonder if tasker could do it… 🤔
I don’t think applications can reboot the phone.
Technically they can…but it requires root which within the context of this conversation yeah, you’re right, lol
Thanks for taking the time to write that out. I found it really helpful.👍
I love to talk about computer security. I don’t get the chance often enough.
I hope you get more chances to do so; you explained the situation in a much better way than the article and convinced me to reboot my phone.
You restart your phone because of security.
I ‘restart’ my phone, because it’s overheated and lost its battery % to 0.
We’re not the same.
