The decoy passcode feature should boot into a separate partition that looks like a normal phone setup, and during that time quietly erase the user's actual data. They would never have known if it worked like this.
Not physically possible[1] to be deniable and a bad[2] idea.

That seems overcomplicated and opening yourself up to risk
IMO the correct solution is to erase your phone before crossing the border, and then restore it after you’ve crossed
No recent messages and no recent email would be a pretty big giveaway. It’s a lot of work to make the decoy part of the phone look genuine.
Does the GPS trail of your running app show you were at a protest site? Better remember to remove that as well. What about all the photos you took on your trip - there’s location metadata in there. Maybe the messenger app stripped that out, but what about the one picture you sent by email - is that still in your offline Sent folder?
100% I have built similar behavior in my [0] encrypted storage app for iOS. User creates a "duress vault" which is an ordinary vault that user can store any data they want (usually something very inconspicuous). If this vault is opened, it will wipe out all the other vaults silently without actually showing any sign of doing so and still preserving the duress vault's data. Even if snapshot of files is made, the index and keys are gone and can't be recovered.
Is there a way to implement this on my Android phone?
Cops collaborate with tech corps all the time now. Generational churn means the cops now are not tech illiterate Barney Fife's
They’re GenXers and Millennials who grew up with this shit and would likely see the bullet point in the press release. Would not be shocked if large departments have someone on retainer or staff to track tech updates
HN crowd continues to display a complete lack of awareness that society moved on from this crowds 15 minutes of fame that was the 2010s
Probably, but it will be more valuable for society for him to be tried and found not guilty, setting a legal precedent.
