Allanonymous That is not GrapheneOS. It could perhaps be something that started as a fork of GrapheneOS, but it stops being GrapheneOS when you make changes to it.
Those changes mostly sound like security theater.
Additionally, this is not relevant to a thread about a new release.
GrapheneOS has plans to add features like a duress password, and that is mostly developed and ready to ship, but the project won't add security theater features such as "hiding apps".
