I live in a big city in the center. When i activate “Show bluetooth devices without names” in the developer settings of my android 13 phone, there appear loads of this devices. I have no clue what they are. Does anyone know? Are that the bluetooth nanobots of the vaxxinated people? (/s to last question!)
There’s an app called AirGuard put out by a German university, it scans for air tags in your vicinity. Useful if you are worried about someone slipping an AirTag on your person/belongings to track you.
