I think the issue is then you have to wait until you are already inside the hotel to use those shakers, which as others have said don’t actually exist in most hotels, and at that point you have been tracked to your exact location. Then it would be trivial to surveil you with other methods without needing your phone.
- JacobThreeThree 5y agoPretty sure Google uses dead reckoning geolocation tracking when no signal is available. So as long as your phone is outside of the bag at some point, you're being tracked even when the phone is in the bag, and Google can correct any errors in their dead reckoning calculations once a signal is found.
- BenjiWiebe 5y agoIt's possible, but I'd be surprised. Dead reckoning is terribly inaccurate. To get briefly acceptable accuracy, you need extremely precise sensors that you are reading very very quickly (which would make battery life plummet).
