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.
