If the WiFi is on, you broadcast your MAC, which is uniquely identifiable unless you root your phone and install software to change this fact.

- zaarn 9y agoIIRC current android and iOS devices will probe Wifi using a randomized MAC and only use the real mac once connecting for realsies.
- michaelt 9y agoresearchers found that "the overwhelming majority of Android devices are not implementing the available randomization capabilities built into the Android OS," which makes such Android devices trivial to track. [...] Apple, meanwhile, introduced MAC address randomization in iOS 8, only to break it in iOS 10. [...] its network probe broadcasts to include a distinct Information Element (IE), data added to Wi-Fi management frames to extend the Wi-Fi protocol. https://www.theregister.co.uk/2017/03/10/mac_address_randomization/ https://www.theregister.co.uk/2017/03/10/mac_address_randomi... four scholars from the US Naval Academy say they've managed to track 100% of all test smartphones, despite the devices using randomized MAC addresses. [...] The novelty in our method is that we are sending RTS frames to IEEE 802.11 client devices, not APs, to extract a CTS response message which we derive the true global MAC address of that device. https://www.bleepingcomputer.com/news/security/researchers-break-mac-address-randomization-and-track-100-percent-of-test-devices/ https://www.bleepingcomputer.com/news/security/researchers-b...
