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!)

    Just wait until you hear about how AirTags work:

    Apple AirTags emit a Bluetooth signal that anonymously connects to any nearby device active within Apple’s Find My network (any iPhone after iPhone 11 with “Find My” enabled). The AirTag’s location is triangulated based on the strength of the Bluetooth signal sent to those third-party devices.

    Your AirTag’s location information is uploaded to the cloud and pinned on a map for easy reference.

      That’s how it’s expected to work, yes. As does Samsung SmartTags, and Tiles. These tracking devices (that we purchase and opt-in for) are a net positive in most cases. How else would we expect them to work if not for Bluetooth beacons (and UWB)?

        When you buy a new iPhone, is the location tracking “Find My” feature enabled by default, or do you need to turn it off if you don’t want your phone to upload other people’s location data to Apple while draining your battery?

          Yes, it is turned on by default. You can opt-out if you’d like. Here’s a pretty good article that covers it all: https://www.howtogeek.com/725842/what-is-apples-find-my-network/

          Samsung SmartTags “Find” network is opt-in, which stagnated the growth of their network.

          Tile’s network is naturally opt-in as it requires us to install the app, and therefore has the lowest coverage from my understanding.

          I recall seeing the following approximate numbers:

          • Apple: 1,000,000,000
          • Samsung: 300,000,000
          • Tile: 35,000,000

          Battery and data usage are negligible.
