Microsoft is keeping quiet about sales figures of Windows Phone 7 devices, so we have to look to retailers for some actual numbers. UK retailer MobilesPlease has released data that shows early WP7 phone sales were “unusually disappointing,” going on to state that only 3-percent of the company’s sales were from Microsoft’s new mobile OS.

This amounts to Android outselling Windows Phone 7 devices by a ratio of 15:1 which is highly impressive, although not surprising. Even Symbian outsold the OS, with just one phone they managed to outsell it 3:1.

Now these results are only from one retailer, but MobilesPlease reached out to fellow retailers in the area, and although they were not given specific numbers, the other retailers simply stated that “Windows Phone 7 devices are not selling.”

So Android is growing in popularity, even with it’s new rival from Microsoft. With all of these impressive figures we keep seeing, it will not take long for Android to become the top mobile platform in the world.
