Also google maps on IOS will do the same, if you allow it. There's quite a bit of phone software that will do that. Facebook, Instagram, games. Make sure you don't allow an app like that to run in the background or send notifications. FaceBook and Messenger shouldn't be allowed to use cellular data - your consent there is treated as a blanket permission to track you mercilessly. You can put a phone into an RF isolation bag but put it on airplane mode so it won't use up the battery frantically searching for RF connections...Also be wary of microphone, speaker, camera, and photo permissions - those devices and data can be used to locate you or communicate surreptitiously.
And of course having an FR login puts you on the radar of the fusion centers and anyone else sampling data at peering points, because FR doesn't use HTTPS everywhere.
I specifically said “out of the box factory-shipped condition” and noted that if you put third party apps on, those apps can track you but it’s on your own responsibility at that point.
As shipped, all Android phones phone home to Momma Google with all your personal, detailed, un-anonymised information and iOS devices don’t.
