Google's Android mobile operating system surged past Apple's iPhone and Canada's Blackberry in the third quarter to become the second biggest smartphone platform after Nokia's Symbian, research firm Gartner said on Nevember 10.
Gartner said Finland's Nokia sold 29.5 million smartphones during the third quarter of the year for a 36.6 percent share of the world-wide market, down from 44.6 percent a year ago.
Sales of Android-powered smartphones soared to 20.5 million units, giving the Android platform a 25.5 percent market share, up from just 3.5 percent a year ago, Gartner said.
Apple's iPhone was next on sales of 13.5 million units for a 16.7 percent market share, down from 17.1 percent a year ago. Canada's Research In Motion, maker of the Blackberry, was in fourth position with sales of 11.9 million units. Its market share dropped to 14.8 percent from 20.7 percent a year ago.
Microsoft's Windows Mobile saw sales of 2.2 million units giving it a 2.8 percent market share, down from 7.9 percent a year ago, Gartner said.
"Smartphone (operating system) providers have entered a period of accelerated platform evolution, stimulated by more regular product releases, new platform entrants and new device types," said Roberta Cozza, principal research analyst at Gartner.
