According to a research from Strategy Analytics, Samsung's Galaxy S3 overtook Apple's iPhone 4S to become the world's best-selling smartphone model for the first time ever in the third quarter of 2012. "Samsung's Galaxy S3 smartphone model shipped 18.0 million units worldwide during the third quarter of 2012, said Neil Shah, Senior Analyst at Strategy Analytics. "The Galaxy S3 captured an impressive 11 percent share of all smartphones shipped globally and it has become the world's best-selling smartphone model for the first time ever. A large touchscreen design, extensive distribution across dozens of countries, and generous operator subsidies have been among the main causes of the Galaxy S3's success. Apple shipped an estimated 16.2 million iPhone 4S units worldwide for second place, as consumers temporarily held off purchases in anticipation of a widely expected iPhone 5 upgrade at the end of the quarter."

Neil Mawston, Executive Director at Strategy Analytics, added, "Samsung's Galaxy S3 has proven wildly popular with consumers and operators across North America, Europe and Asia. However, the Galaxy S3's position as the world's best-selling smartphone model is likely to be short-lived. The Apple iPhone 5 has gotten off to a solid start already with an estimated 6.0 million units shipped globally during Q3 2012. We expect the new iPhone 5 to out-ship Samsung's Galaxy S3 in the coming fourth quarter of 2012 and Apple should soon reclaim the title of the world's most popular smartphone model."
