Shared here for public benefit.

Before going to a protest, demonstrators or observers should note that their cellphones may subject them to surveillance tactics by law enforcement. If your cellphone is on and unsecured, your location can be tracked and your unencrypted communications, such as SMS, may be intercepted. Additionally, police may retrieve your messages and the content of your phone if they take custody of your phone, or later by warrant or subpoena.

Leave it at home for a protest if you care about being tracked.

Pretty much all cell phones can be tracked even when turned off.

Could you not wrap it in thin foil to make a faraday cage? If done well it should prevent any signals for going in or out.

Even with a libre OS and all radios turned off? (So to use the phone as a camera and offline navigation)

[–] GreenKnight23@lemmy.world 3 points 6 hours ago

yes, even with all the foss software and radios turned off.

it will still ping radio towers. the only exclusion are phones with physical switches for disabling hardware.

I feel like it could still get damaged or used as evidence in court if you get caught up in a crackdown.
