Best idea for individuals with reason to be targets of the State is to forgo the smartphone altogether. Always keep a burner dumb phone with you for emergencies, not tied to your personal information. All it would have is numbers of people you texted/called. If you must have smartphones keep them as distinct devices that you don't do anything important with. Like maybe one to use Google Maps and order Doordash with.

On that note, I'm going to buy a MyPillow just to stick it to the man.
