As I understand it, a smartphone is also able to be tracked when the device is powered off. The only solution is to remove the battery (difficult if it's soldered), or to leave it at home.
Most people don't carry portable Faraday cages.
- jamescostian 9y agoThe part about the battery is very interesting! I googled it and couldn't find any more information though... do you have any links?
- politician 9y agoHere's a link. https://www.techdirt.com/articles/20130723/12395923907/even-powering-down-cell-phone-cant-keep-nsa-tracking-its-location.shtml https://www.techdirt.com/articles/20130723/12395923907/even-...
- jamescostian 9y agoWow! I never heard of that. It looks like that article is about govt applying spyware to phones, like how they also made companies give them user data. By the same token, I guess the govt could work with car manufacturers to install tracking devices in every car...
- jacquesm 9y agoTesla is helping a bit here, free of charge.
- jacquesm 9y agoThat's only true if the baseband is still alive and pinging the tower. That's easy enough to find out (field strength meter, $5 in parts next to the phone).
- Spearchucker 9y agoA smartphone (actually any cellphone) can be detected when it's powered off (assume flat battery), but not tracked. Works using ferromagnetism, which also detects explosives.
