HoldMyBeer Will Duress wipe only delete all user data? System settings and OS updates and installed apps remain installed?
A Duress PIN will delete User data, profiles, esims, installed apps, photos, files, etc. After the reset has been performed, you will end up with GrapheneOS like you did when you installed it. Go through the welcome screen, be taken to the black homescreen with the system apps (Vanadium, contacts, messages, etc.) and have to set up everything new again. Have you read through this yet?
