Achieved following respective summer launches in 2010 and 2011.
Samsung's flagship line has grown into the world's most desired smartphone – along with iPhone – with the Galaxy S passing 24 million sales in two years, while the S II has hit more than 28 million in just one year.
Meanwhile, its Galaxy Note 'phablet' device has hit the seven million milestone in seven months.
And the signs look good for the future of the brand too. The new Galaxy S III launched this week with nine million pre-orders.
However, it still has a way to go to compete with Apple's most recent quarterly sales of 30 million iPhones.
