  A proper Faraday cage, a truly excellent one, just the most Faraday of all the cages, is easily defeated by physical attacks such as getting your phone cloned when you get mass arrested and summarily released on OR.

  Faraday cage does not prevent gyroscopes and accelerometers from working. Then if you remove it from a faraday cage in the future, it will transmit all that movement

    Since you’re posting this all over the thread, I’ll also have to repeat the information that gyro/accelerometers are not capable of doing that. Small measurement errors stack up and throw it completely off.

    Without GPS or tower based error correction any location prediction based on conservation of momentum in the phone will be useless before very long if the phone is moving.

    Sounds theoretically possible I guess…
