25% of Windows Phone devices run WP 8.1, Microsoft undisputed monopolist in terms of hardware
43
Windows Phone 8.1 has begun its rollout roughly a month and a half ago, and although we know that the platform is apparently stalling at the moment, it's pretty interesting to see how the latest iteration of Redmond's OS has been adopted across the user base.
Fortunately, the guys over at AdDuplex have provided data about the stats we are interested in, and from the looks of it, the spread of Windows Phone 8.1 now spans to 24.4% of all Windows Phone devices, whereas its predecessor, Windows Phone 8 still makes 56.5% of all WP devices click and tick. The earlier versions of Windows Phone, the likes of Windows Phone 7 and 7.5, combined account for the remainder of 19.2%. All in all, that's a significant growth for Windows Phone 8.1 in comparison with July.
