Advertising service AdDuplex has published the company's report for Windows Phone for the month of December, breaking down Redmond's mobile platform. Using a selection of apps, the company has been able to provide some data as to which handsets are more popular and who is rocking the latest OS release.

Give it another month ad we should hopefully see Windows 10 Mobile surpassing Windows Phone 8. Aside from the OS figures, the AdDuplex report also showed how the Lumia 950 was more popular in certain markets, including the U.S. where it was noted as being more than twice as popular.

In the U.S., the Lumia 950 is twice as popular as the Lumia 950 XL

In France, the Lumia 950 is more popular than the Lumia 950 XL

In the UK, the Lumia 950 XL is more popular than the Lumia 950

In Australia, the Lumia 950 XL is more than twice as popular as the Lumia 950

The Lumia 950 appears in India, but 48 other Windows Phones are currently more popular than it

As well as numbers, we were also greeted by various unannounced handsets that appeared in the report. These included the RM-115 handsets from Microsoft with 5-inch 720p displays, a possible LG tablet (LG V496), and even an Acer S58xW WxGEN1 with two resolutions on a 5-inch screen - potential Continuuum supported hardware? Finally, there's also the mention of a 5.4-inch HP Falcon.
