DeletedUser1026 I'm not system developer but I see what GOS team accomplished and sure that's easy for them to pull.
I see. Unfortunately that's a wrong assumption. The project has reiterated many times that adding even minor features is not at all easy, and this wouldn't be a minor one. It requires a huge amount of design and labor to do these things, on top of the huge amount of work they do to maintain the OS at such a high standard of security and privacy.
DeletedUser1026 Duress pin option shouls be also available for wiping secondary profile or private space, to be used stealthy
DeletedUser1026 I don't know whether deleting secondary user or private space leave traces for forensic tools
The response here from matchboxbananasynergy, who was at the time a mod and speaking for the project, should make clear that such a feature would leave forensic evidence and not be stealthy:
There is no way to hide this, and will therefore not be done.
it would not be possible to hide from someone who is aware the feature exists, especially if they have physical access to the device for a prolonged amount of time.
The duress PIN/Password is meant to irrevocably wipe the device's contents. It's not meant to be stealthy. That's a goal that can't be meaningfully achieved.
It seems the project has already considered this idea and chose not to pursue it for those very reasons. Perhaps we should trust the team, who have far more intimate knowledge of these things than we do.
