Tell HN: Your Android carrier can remotely turn settings on
Wait until your learn what a country or local government/police can do remotely to the baseband firmware of your phone with a court order...10-20 years ago the FBI was regularly remotely programming firmware to listen in and record cell phone microphones to capture conversations of suspects.  IIRC a mafia case hinged on data gathered in this way so it is not some abstract theoretical or crackpot theory (https://www.cnet.com/news/privacy/fbi-taps-cell-phone-mic-as...).It's only gotten worse as phones have gotten more capable.  You don't own squat about the device in your pocket at all times.
