![]() (The researchers know only that they received about 60,000 randomized MAC addresses from Android phones. Of the roughly 960,000 Android devices that were scanned over a two-year period, fewer than 60,000 of them-and very possibly as few as 30,000 of them-randomized their addresses, even when running OS versions that supported the feature. Newly published research, however, has found Android's MAC randomization to be largely absent. Full implementation went live in March 2015 and is currently available in version 5.0 through the current 7.1 those versions account for about two-thirds of the Android user base. A few months later, Google's Android operating system added experimental support for the measure. Apple introduced MAC address randomization in June 2014, with the release of iOS 8. Only when a phone actually connected to a Wi-Fi network would it reveal the unique MAC address it was tied to. That way, Wi-Fi devices that logged MAC addresses wouldn't be able to correlate probes to a unique device. Their solution was to rotate through a sequence of regularly changing pseudo-random addresses when casually probing near-by access points.
