Why do you think that they can track you when it is turned off?
My understanding is that even when you turn your phone “off,” it’s not really off. This is anecdotal on my part. Could be wrong.
“Why do you think that they can track you when it is turned off?”
They’ve been able to do that for a long time. A few years ago someone — I think it was Stossel, but not sure — did an expose on this. Cell turned off, and I think that the battery gone, later Google provided a printout of every place the person had gone. It even made assumptions that the person had stepped out of the car at a specific time. (It was true; he had.) Some other gizmo in the phone does this.
