To piss off the right people accordingly:
- Use the most recent phone you possibly can
- Upgrade your phone to the newest possible generation as soon as possible after release
- Use the latest version of GrapheneOS ASAP
- Use a strong high entropy passphrase (makes bruteforce impossible if secure element is exploited)
- Set auto reboot time accordingly so encrypted data goes back at rest when the phone reboots.
- Turn phone off when in a risky situation.
- Disable radios when not using them (turn off Wi-Fi, use airplane mode, disable NFC, UWB etc.)
- Set an appropriate USB port control
- Use user profiles (data stored encrypted with separate credentials)
- Enable duress password when it comes out
- Enable second factor authentication unlock when it comes out
