At least hidden profiles would be good enough for basic protection.
They have this which wipes your device, but you can get killed under duress. https://discuss.grapheneos.org/d/14722-using-duress-password...
We think there's a good chance a motivated adversary is going to be familiar with GrapheneOS and its features, and the more mainstream it becomes, the more this can mean "your abusive significant other" rather than someone at the border.
The moment people know this feature exists, it can become dangerous even if you don't use it. You can be threatened to unlock, and even if you do, the adversary can choose to not believe you since they can think you're just hiding it. That puts you in a dangerous situation where they think you can provide something that's literally not there.
It's a very difficult problem to solve, and we don't think that proposal can solve it.
Let’s say someone have you at gunpoint, you can just give your mains profile pass.
If they don’t even know there is a secret profile you’re good to go.
You’re right, they might assume you’re hiding, but I’d say 99% won’t know what’s even graphene and from those who know I’d say they might force you and you can have 3 sets of bank accounts:
Main profile: 100 Secondary: 1000 Terriary: $$$
Also if you hide all traces of grapheneos would be safer too. Nobody even knows is graphene, so they can’t even check what features you have. Again we are talking about 99% of the criminals, not the tech savvy 1%.
I’d prefer plausible deniability like Vera crypt than what we have now.
It's not about criminals. It's about the police, government spy agencies, and other knowledgeable threat actors.
