Android (211.6 million devices) also enjoyed a year-on-year increase in market share from 74.9% to 81.0%. By contrast Apple's iOS (33.8 million devices) saw its market share fall from 14.4% to 12.9%, as did BlackBerry (6.8 million devices), from 4.1% to 1.7%.
Nokia's own numbers indicate that it shipped 8.8 million Lumia devices in Q3 2013, which using IDC's numbers, indicates that non-Nokia manufacturers (HTC, Samsung, and Huawei) shipped just 700,000 Windows Phone devices in the last quarter. In percentage terms Nokia shipped 93% of Windows Phone devices in the third quarter of 2013.
In the press release IDC also noted that Windows Phone shipment are domintated by Nokia:
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.
Ramon Llams, Program Manager with IDC's Mobile Phone Team, noted that Android and Windows Phone sucess was driven by price.
"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. 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."
Longer term context
Q3's smartphone numbers continue the seemingly inexorable growth in smartphone shipments. Android's dominance of the smartphone market is illustrated in the chart below, as is iOS declining market share, and Windows Phone's comparatively small market share.
However, as we've previsouly menioned, some caution should be used in treating each platform blocks as a single entities in the smartphone space. Most notable Android can be considered to consist of several platforms, with the most important divide being between devices with Google Services (what most people in Western markets think of as Android) and devices based on the Android Open Source Project (how most people in China experience an Android device).
