TIL that on newer Samsung phones, you can't use the camera *at all* unless you give the app permission to scan your environment for other devices. There is no way to opt out of this. Little by little, inch by inch, the surveillance infrastructure that surrounds us is becoming total/complete/absolute. If you were trying to assemble a fascist dystopia, this is exactly the kind of equipment you'd make everyone carry around all the time.
I was one of the last hold-outs to finally give up my old-timey flip phone and hop on the smartphone bandwagon, and tbh I'm seriously considering going back.
