AdDuplex has released their monthly numbers for measuring the Windows Phone ecosystem. Perhaps the biggest news to come for February was the down revision of the Windows 10 Mobile numbers compared to Windows Phone 7.x and 8.x.

The revision is not due to people dropping off the next-gen OS but rather to the incorrect inclusion of some devices still running Windows Phone 8.1.

As a result, the previous month's report of 9.5 percent for devices running Windows 10 Mobile drops to a much more sobering 5.3 percent.

Windows 10 Mobile is currently only available to two segments of users:

  • Windows Insiders who opt in
  • New devices like Moly X1, NuAns NEO, Lumia 550, 650, 950, or 950 XL

Although there have been isolated reported of official upgrades most users with phones running Windows Phone 8.1 have not had the option to update to Windows 10 Mobile automatically.

Unfortunately, with such a low number for Windows 10 Mobile it still makes little sense for developers to aggressively target the platform versus Windows 10 for PC. Microsoft is banking on developers making mobile versions of their apps due to the ease of Windows 10 tools but clearly there is some time yet for the ecosystem to transition for users.
