In the US, the world’s largest smart phone market, HTC shone in Q3 2011, edging out Apple Inc and Samsung.

With year-on-year and sequential growth of 252% and 60% respectively, Samsung shipped 27.3 million smart phones under its own brand to capture a 23% share, becoming the number one vendor in APAC, Western Europe and Latin America, ahead of Nokia Corp (NYSE:NOK), Apple Inc (NASDAQ:AAPL) and Research in Motion Ltd (NASDAQ:RIMM) respectively, according to Canalys's Q3 2011 shipment estimates.

With well-regarded products, such as the Galaxy S II, and significant marketing campaigns, the vendor registered the second highest quarterly shipment total in the market’s history, behind only Nokia’s Q4 2010 performance. In addition, Samsung shipped an estimated 500,000 units worldwide under the Google and T-Mobile brands.

United States

In the United States, the world’s largest smart phone market, HTC shone in Q3 2011, edging out Apple and Samsung to become the leading vendor. HTC shipped 5.7 million smart phones in the US under its own brand, giving it almost a quarter of the market, as well as an estimated 70,000 units under the T-Mobile brand.

Samsung pushed Apple into third place in the US market, with shipments of its own-brand devices reaching 4.9 million units. Apple’s US smart phone shipments totaled 4.6 million in the quarter and it was affected around the world by consumers waiting for the launch of the next-generation iPhone.

Research in Motion

RIM had another tough quarter in its largest market, where its volumes declined 58% from a year ago and its US market share slipped from 24% in Q3 2010 to just 9% in Q3 2011. It continues to face unfavorable press there and its volumes have dropped significantly despite a refreshed product line that includes its flagship BlackBerry Bold 9900.

UK-based Canalys Senior Analyst, Tim Shepherd: "RIM’s market share has fallen below 10% for the first time, and the current outlook for it in the US is certainly bleak. While Apple can for now get away with not having a 4G smart phone, no other vendor in the US can. RIM must deliver a competitive high-end 4G smart phone in early 2012."

China

Canalys’ research also revealed huge growth in the smart phone market in mainland China, where shipments in Q3 2011 increased by an impressive 160% on a year ago to 23.2 million units. While maintaining very high growth potential, just over 200,000 fewer smart phones shipped in China than in the United States, leaving it a hair’s breadth away from being the world’s largest smart phone market.
