Android continued its overall upward trajectory, reaching triple-digit growth for the year. Samsung was the biggest contributor to Android success, representing 42.0 percent of all Android smartphone shipments during the year. iOS posted another quarter and year of double-digit growth with strong demand for the iPhone. However iOS's year-over-year growth has slowed compared to the overall market. BlackBerry's tight grip on enterprise users has loosened and its popularity within emerging markets has been diminished by competition as a result of the company's decision to postpone the release of BB10 to 2013. Windows Phone/Window Mobile made market progress in the fourth quarter and for the year, driven by Nokia's strong commitment to the platform. As the same time, the relationship has benefited Nokia, which represented 76.0 percent of all Windows Phone/Windows Mobile smartphone shipments. Linux remained essentially flat from the previous year, with longtime supporters NEC and Panasonic moving to Android and newcomers K-Touch and Haier making up the difference.
