Windows Phone posted the largest year-over-year growth worldwide of any of the leading operating systems, a result primarily driven by the support of Nokia. By itself, Nokia accounted for 93.2% of all the Windows Phone-powered smartphones shipped during the quarter, marking a new milestone in the company’s short history on the Microsoft platform. Participation from other vendors, meanwhile, still seemed a mixed bag with more vendors participating from a year ago, but volumes still far behind Nokia’s own. iOS, despite seeing its total volumes increase and reaching new record third quarter volumes, saw its market share decline during Q3 2013, most likely due to soft demand in the weeks leading up to the launch of iOS 7 smartphones. Still, if the 9 million units sold during the last week of September is any indication of future adoption, iOS stands to reap another record quarter in terms of volumes, market share, and year-over-year growth.
