personally, my bet is that they don't have anyone qualified enough to pull off an exploit like that (on me).

the problem with my bet: what we've seen is that they won't care, and accuse individuals of terrorism based off the color of their clothes.

Yeah tails does have graphene beat, but a lot of folks see a phone as a necessity. Graphene is best if you're gonna have a phone. It can turn off the USB port where it can't even be charged without being off. It can reboot itself if not unlocked frequently enough, putting the phone back into a BFU state.

Now it's possible that there's some exploit a state knows that is not public, but the software they generally use does not work on graphene as long as you are not running a pre-2022 version of graphene. Someone else mentioned rubber-hose cryptanalysis, but like if I'm getting beat for my unlock, then what do I care about getting charged with destruction of evidence?

If you have info about someone getting a graphene phone to turn the USB back on, please share as I'd like to read about it.

I don't think saying the state can torture us for info is a phone security issue per se. Especially since the only way to avoid imperial state violence is to shut up and do nothing and hope they don't come for you anyway
