How precise is that?Yes. In fact, there's a search and rescue organization that uses that technique to find missing people.

I don't recall what the circular error of probability is, but it's pretty accurate. I'm guessing, but I'd say within a mile which is close enough for SAR teams. Perhaps not for government tracking.
Even so, I seem to recall that with location service, GPS, wifi, and Bluetooth off, android phones store location data and report it back later. So, you're still being tracked. I don't recall the source of that info and I could be wrong.
Yes, they can. They use a mode called time difference of arrival (TDOA) to triangulate. It will not be as accurate as if they had your GPS data, but it gets them close. I agree with the statement that if you turn OFF location, WiFi, and Bluetooth you should be good FOR NOW. Do I think they cannot turn on a "stealth mode" on your phone when they want to? No.I do wonder if cell towers can triangulate a position though.
So then obviously, it's tracking some other way?
I could understand reporting back later, if that stuff was still on, but not if off.
Your cellphone can be tracked even when it's turned off. It's like a computer is never really off just asleep, mostly. Some things can be active even when off if programmed that way.
So, does one need to be being "investigated" to be followed like this, or could it happen on a "whim", say 3 weeks later?
I'm not sure what you're asking. From what I understand, the data is stored and then uploaded when you connect to wifi/mobile data/etc. I know in SAR, old data has been used to find missing persons. While I would think it would take a warrant or probable cause for "officials" to access that data, I wouldn't be money on that requirement.
Imagine, if you will, a highly-decorated general, a fake dossier, and abuse of the FISA courts...While I would think it would take a warrant or probable cause for "officials" to access that data, I wouldn't be money on that requirement.
FIFY!!!That's "C2C" service.....
FIFY!!!
Same question....

Holy crap.
.
Is it made in China?That's about all I have to say myself.
Not sure if it would help, but maybe the cheap flip phone from Walmart I have might need to be my regular phone. I don't think it is "smart" in any way, but I could be wrong.
