So for access to your phone under normal circumstances would you use something other than biometrics then? Like a passcode or something?

that’s an interesting idea, but what would you mean exactly? Like biological signs of duress being detected or a secret duress biometric pass that’s distinct from the one you’d normally use such as one finger and not the other? Because the first option would be bad news if you felt stressed one day and tried to use your phone and the 2nd option would I guess be just as bad as the passcode wouldn’t it? They’d say you used a duress biometric instead of the normal one you’d otherwise have used and it wiped the phone, interfering with their investigation and destroying evidence and then prosecute you for it.
