Microsoft’s decline in market share of U.S. mobile smartphone platforms seems to have leveled off.
For the three months ending in August, Microsoft’s smartphone platforms — primarily Windows Phone but also older Windows Mobile — had 5.7 percent of smartphone subscribers, according to research company comScore’s August 2011 U.S. Mobile Subscriber Market Share. That’s about level with the 5.8 percent held by Microsoft platforms for the three months ending in May.
Research in Motion had a far more serious decline for the three months ending in August versus the three months ending in May, going from 24.7 to 19.7 percent of the market. Google’s Android platform shot up from 38.1 to 43.7 percent.
Overall, 84.5 million people in the U.S. owned smartphones during the three months ending in August, up 10 percent from the preceding three month period, according to comScore.

Microsoft is pinning its hopes for a boost in market share on Mango, the latest update to its Windows Phone 7 platform. Mango, which adds some 500 features, started rolling out to existing Windows Phone users last month. New handset models featuring Mango are expected to hit stores later this fall.
