Nokia Lumia 520 is World's Best-Selling Windows Phone Device

Nokia's Lumia 520 Windows smartphone has emerged as the world's best-selling Windows Phone 8 (WP8) phone.

The latest data from Adduplex, a Windows-based cross-promotion network for applications, states that Nokia's cheapest Lumia model, the 520, accounts for 18% of all Windows Phone handsets sold, and 27% of all WP8 handsets.

Another interesting snippet of information which has come out of the survey shows that overall 57% of WP8 smartphones use just 512 MB RAM, which indicates that lower-end devices are the best-selling devices running Microsoft's operating system.

Almost 65% of WP8 handsets are made by Nokia, with that percentage rising to a huge 86.9% when taking into account all Windows Phone smartphones (including models running Windows Phone 7 and Windows Phone 7.5).

While all of this looks like good news for Nokia, it must be remembered that Windows Phone only accounts for 3.3% of all smartphone sales, trailing Android (80%) and Apple iOS (14%) by some distance, according to the latest figures from Gartner.
