ComScore: Microsoft's mobile phone market share slipping

Nokia may have launched the Lumia 710 in the US in January, but the biggest smartphone launch yet for Microsoft's Windows Phone OS apparently didn't help the company's market share against Apple, Google and Research in Motion. A new report from ComScore today states that Microsoft's share of the smartphone market went down from 5. 4 percent in October 2011 to just 4.4 percent in January 2012 in the US.

Google's Android OS continues to dominate the smartphone market with 48.6 percent in January, up from 46.3 percent in October 2011. Apple's iOS commanded 29.5 percent of the market in January, compared to 28.1 percent in October. RIM's Blackberry OS saw its market share dip from 17.2 percent in October to 15.2 percent in January.

ComScore also said that January was an important month for the smartphone industry in the US. For the first time, over 100 million US mobile phone customers now use smartphones. Overall, 234 million US citizens age 13 and above use some kind of mobile phone device. Samsung is the number one smartphone manufacturer in the US with 25.4 percent of the market in January. LG was second with 19.7 percent, followed by Motorola with 13.2 percent, Apple with 12.8 percent, and Research in Motion with 6.6 percent.
