The June numbers are out from AdDuplex, one of the largest advertising platforms for Windows Phone and developers. The figures are gathered from apps running on Windows Phone and are used to measure market share within the Windows Phone ecosystem. Because there are fewer new phones hitting the market, there is even less movement this month over last. Instead, we see the continued trends of the Lumia 63x and Lumia 535 growing in many regions, including in the US, France, Italy, and Poland. However, these are modest shifts mostly at the cost of declining Lumia 520 users.

Microsoft and Nokia continue to control the Windows Phone market with a massive 96.74 percent of all devices. Those utilizing Windows 10 Mobile on their phone now account for 2.5 percent of all Windows Phone users, a number certainly to grow in the coming months. As AdDuplex notes, this means one out of every 40 Windows Phone users is on Microsoft's next-gen phone OS.
