In the third quarter of 2013, smart phone price mattered.
With a total base of 211.6 million smartphone units shipped during the quarter, Android accounted for 81 percent of all smart phone shipments.
Microsoft's Windows Phone grew 156 percent year over year from a small base of 3.7 million units in the third quarter of 2012, reaching overall market share less than five percent, according to IDC.
"Android and Windows Phone continued to make significant strides in the third quarter. Despite their differences in market share, they both have one important factor behind their success: price," said Ramon Llamas, IDC research manager.
"Both platforms have a selection of devices available at prices low enough to be affordable to the mass market, and it is the mass market that is driving the entire market forward," said Llamas.
Smart phone average selling prices were lower by 12.5 percent in the third quarter of 2013, to an average price of $317.
