SignalTrace “links devices that regularly travel together, correlating them to license plate.” It is a surveillance product that will sweep up and add all sorts of Bluetooth and other data to license plate readers, linking specific devices—and people—to cars.
My old phone is still Android 12, if I enable Airplane mode, WiFi, cell, BT turn off immediately. Idk About newer OSes like that says. You could maybe it’s a different phone with BLE to test scanning for other devices?? Idk, I gotta look into this one now! TY for sharing.
