My understanding of how Eric Adams did it is he took the phones into the bathroom and changed the unlock keys to random and instantly-forgotten strings. That way nobody could force him to reveal it. But that plan relies on being handed the phones and allowed to go into the bathroom.

There is a constant cat and mouse dynamic between the companies that make mobile phones and their operating systems, namely Apple and Google, and the firms making tools to break into those devices.

Where google is concerned, that is a very kind way to put it.

If you have an ios device, turn off biometrics, turn on adp (actually store your code in a safe place!), turn on lockdown and start aggressively powering your phone off when you’re not using it.

Learn the duress combinations, on iOS it’s the side button five times. From there you can make an emergency call, power the phone off or cancel out and unlock with pin only (no biometrics).

Use this screen to power your phone off so when its confiscated it boots into bfu (before first unlock) state.
