lumia920-lNokia’s Lumia 920 is now the most widely used Windows Phone device, reaching 14 percent of usage, and Nokia is by far the biggest maker of Windows Phones, with upwards of 80 percent of the market for Microsoft-powered devices.

That’s the word from AdDuplex, an app-promotion service for Windows Phone and Windows 8, drawing from its latest data about Windows Phone usage. The Windows Phone Central news site is reporting on the numbers in advance of their public release.

By comparison, the HTC 8S and 8X together have 8 percent of the market, according to the data. Samsung’s Windows Phone devices are lumped into the “other” category in the AdDuplex report. Samsung is the leading maker of Android devices and its mobile chief has called the demand for Windows devices “lackluster.”

That’s a big gap between Nokia and other makers of Windows Phones — perhaps more than might be considered healthy. It could help to explain reports that Microsoft is working on its own Windows Phone, which could help to balance out the equation with another flagship device.

Comparing old and new versions of Windows Phone, the AdDuplex numbers show Windows Phone 8 with 43 percent of Windows Phone usage (up from 19 percent in January), and Windows Phone 7 with 57 percent.
