Yeah if they can catch you and prove it.
replyEven if they can’t prove it, they can make your life really miserable for quite a while.
replyIf it was implemented in such a way, there would be no reason to suspect anyone of using it because it would be totally indistinguishable from not having used it. At that point they have no grounds for legal action. Unless they could monitor FS/disk activity, but that goes beyond typical airport security stuff.
replyI'm imagining a duress code that erases select files and any indication that there was ever a duress code set up in the first place.
As soon as that starts, authorities will charge people just for having GrapheneOS. There are 0 checks and balances right now, it's a free for all.
reply(1) Keep manufacturer's Android plus some plausible apps and data in a reserved part of the drive. (2) GrapheneOS runs from the other part of the drive. (3) Make sure PIN screen designed to not give away the OS. (4) When duress PIN is entered, erase GrapheneOS and restore manufacturer's Android. (5) Now you won't be charged for having GrapheneOS because they won't know you had it.
