I put my old Samsung into developer mode, using a YouTube video. It stopped all sensors and recording, listening from happening. Only pain was to take. Picture or use functions you had to approve every time.
i did it after reading no matter what your privacy settings are on, it can determine where you are by matching with other people’s phones, ie riding on a train or bus etc.
It might be time to do so again. I don’t think any of us signed up to be spied on, or at least didn’t read the user agreement and just ticked the box.
