People, just remember: unless the battery is dead or removed or you have your phone in a Faraday cage (microwave oven works but don’t turn the oven on LOL), it’s trivial to locate your phone (even if GPS is so-called “off”) and to listen to your phone (whether or not you’re on a call).
And by listen I mean remotely listen without you knowing. Oh yeah and also to pretty much any browsing, app use, etc. Note: they are ways to make it tougher.
