AdDuplex says Lumia 640 has outperformed Lumia 520 in US

Just days after online retailer Expansys said that the Lumia 640 XL has been one of their best-sellers over the past few weeks, mobile advertising firm AdDuplex has revealed that the device's smaller sibling Lumia 640 is now among the top-10 Windows smartphones in the US.

The revelation was made by AdDuplex's founder and CEO Alan Mendelevich, who also said that the smartphone has even outperformed the Lumia 520, which according to the advertising company's last month's statistics held 6.4% of the US windows phone market.

If you aren't in the know, both handsets are currently available at discounted rates on Expansys - the Lumia 640 carries a price tag of $175, while the 640 XL will set you back $200.
