Apps watch how we move/rotate devices to understand whether we’re walking, resting, lying down, etc., I assume? (The most popular apps I mean with large data teams)
Wish that stuff could be turned off unless it was e.g. a game that made legitimate use of the accelerometer.

GrapheneOS does allow you to turn it off. It has a permission switch for your phone sensors. I don’t know if there are other versions of android that allow the same.
