Samsung announced that it has sold 40 million Galaxy S III phones, since it launched in May 2012. So the total number of Galaxy S phones sold to 100 million since the first Galaxy S launched in May 2010. Samsung reached this milestone in 2 years and 7 months after the launch of the original Samsung Galaxy S back in May 2010.
Samsung says the Galaxy S III is selling at a rate faster than any other Galaxy phone so far. At present, daily sales of Samsung Galaxy S series phones are 190,000 units.
