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!)
If you live in a city center you are probably in a highly populated area and your phone is receiving the signals from other people’s Bluetooth devices in proximity to you and your phone. Basically your seeing the devices of all your neighbors, because that’s how wireless Bluetooth transmission works.
or in other words, BT devices broadcast their names only in pairing mode, so you know only the names of devices you are paired with.
all other devices continue to be there, but normally not shown, because you don’t know them.
Until you pair, there’s no reason for showing them
