With January on the way out, AdDuplex returns with an interesting look at Windows Phone usage for the month. Also worth discussing: Why Nokia Lumia sales were down quarter over quarter in Q4 2013, but actual Windows Phone sales to customers—and thus activations—were in fact up. It's all here in this month's peek at Windows Phone device usage.
As you may remember, AdDuplex bills itself as the largest cross-promotion network for Windows Phone and Windows 8 apps, empowering developers and publishers to promote their apps for free by helping each other. And each month it provides a tantalizing glimpse at which Windows Phone (and Windows) devices people are actually using.
