Heya folks. I want to attend protests, but they are going to happen fairly far from where I live: to the point where it might be harder for me to navigate without access to my phone. I saw a post today that there are Faraday bags you can get to stick your phone in, which will prevent cops from picking up my cell data. Do you all have any recs or experience with these?
Edit: Thank you all for the recommendations!
Print a map! You can usually also disable data and cellular signals on the device and continue using GPS, with offline maps (Open Street Maps or Google Maps though I'd be wary of the latter's potential to store and sync location data once back online).
Also worth remembering bags aren't foolproof. Can rip, tear, develop small holes.
