For Android: learn the hard reset combo for your phone, especially if you encrypt it.

After rebooting, pattern/PIN will be required to decrypt the phone. Biometrics won’t work for this step. This is what graphene does for security, tries to keep the phone in a “before first unlock” state by rebooting on a timer. You can’t even read anything over USB/ADB, it’s scrambled until you unlock the phone.

The only drawback to just keeping your phone in this state is none of your apps are loaded, so no notifications/updates/processing at all.

Reposting as top level comment also: these are PWDIS drives: if you’re not using them somewhere with sata 3.2/3.3, you need to use an adapter for the power plug, or some tape, to block pins 1-3 (3.3v) as supplying it to these causes them to reset. Might be worth doing the taping anyway, if you’re using an enclosure or cage (where you can’t use the adapters) Just be aware.
