Research analysts Gartner published their latest quarterly smartphone sales report on Tuesday.
Microsoft’s Windows Phone sales remained flat during Q3 2011 according to Gartner. Android’s growth saw the operating hit 52% market share worldwide with Symbian at 16.9% in second place, shortly followed by Apple’s iOS in third with 15%. Microsoft managed to secure just 1.5% market share in Q3 2011, down from a 2.7% market share in the same period during 2010. Android benefited from a number of mass-market offerings according to Roberta Cozza, principal research analyst at Gartner. The operating system reached 52% market share thanks to “a weaker competitive environment and the lack of exciting new products on alternative operating systems such as Windows Phone 7 and RIM,” Cozza said.
Gartner predicts that Microsoft’s Windows Phone turnaround won’t take place until the second half of 2012, mainly due to Nokia’s products. “Heavy marketing from both Nokia and Microsoft to push the new Lumia devices should bring more improvement in the fourth quarter of 2011,” said Gartner.
Gartner has previously predicted that worldwide smartphone sales will reach 468 million units in 2011, a 57% increase from 2010. Android is expected to further hold its lead and account for 49% market shareby 2012. Microsoft’s Windows Phone is expected to increase to 10.8% by 2012, up from 4.2% in 2010. Gartner has also previously predicted that Microsoft will cement a strong second place market share by 2015. The research analysts believe Microsoft’s Windows Phone will account for 19.5% market share by 2015, above Apple’s 17.2%. Windows Phone will also account for 215 million worldwide shipments by 2015.
