  According to The Guardian, the US Department of Justice is prosecuting Atlanta resident Samuel Tunick after he allegedly gave a GrapheneOS duress PIN while border agents were trying to search his Google Pixel phone.

It sounds like he did give them the password, but it was the password to wiping his phone and not unlocking it. I'm surprised they didn't back up the device first.
