Nielsen has posted its report for the second quarter this year, its figure displayed that Android went further, dominating, while the iOS goes second. The two platforms control 86.2% of the US smartphone market.

For the second quarter of this year, Android rules 51.9% in the US smartphone world, while Apple iOS got 34.5%, RIM’s Blackberry OS came third, but the margin is too far below running just 8% of the market.

The range is too large for among the new platforms, among the US citizen that purchased a smartphone in the past three months, 58.6% went for Android, 33.0% were pleased with the iOS gadget. The reason behind topping so largely is that the latest vector of the iOS, the iPhone 4S is nine month on market at the end of the quarter, while the powerful One X Android vector is just entering the market.

As you know that the Samsung Galaxy S III is also new in the US market in the Q3, and the next iPhone is expected to land in market at the core end of the quarter, what we are expecting is the two platforms continues in its expansion and leading the market shares by the time the next polls rolls out.

As shown on the graph, the sale of the BlackBerry went down to 2.7%, while other platforms like the new Microsoft’s Window Phone managed a combination of 5.8%. The Windows Phone is not expected to make a significant move before the Holiday season, as we await the new Window Phone 8 device to launch.
