GrapheneOS provides users with the ability to set a duress PIN/Password that will irreversibly wipe the device (along with any installed eSIMs) once entered anywhere where the device credentials are requested (on the lockscreen, along with any such prompt in the OS).
The wipe does not require a reboot and cannot be interrupted. It can be set up at Settings > Security > Duress Password in the owner profile. Both a duress PIN and password will need to be set to account for different profiles that may have different unlock methods.
Note that if the duress PIN/Password is the same as the actual unlock method, the actual unlock method always takes precedence, and therefore no wipe will occur.
Since you’re all here and Graphene doesn’t work on my ancient 3a, do you have any alternatives you’d recommend?
If i was you, i would buy a Google Pixel 8 (8a is cheaper than 8 and 8 pro). They all provide support for GrapheneOS, have 7 years of updates, MTE, and so on
For context: https://grapheneos.org/faq#device-support
My daily driver is a 7a, my older 3a is the experiment and learn phone
lineageos https://wiki.lineageos.org/devices/sargo/
calyxos https://calyxos.org/install/devices/sargo/windows/ [until August 2024, so not worth it]
divestos https://divestos.org/pages/devices
lineage will give you the most feature complete environment
DivestOS is fun to play with, but even coming from GOS its going to have a big learning curve.
There is always the option of just using the 3A with the stock OS, unsupported, especially if you want to regift the phone to a young relative.
