Samsung have yet another winner on their hands with their flagship Galaxy S4 smartphone, which has now sold over 20 million units. The Galaxy S4 launched just two months ago.
This means that the Galaxy S4 has sold roughly 1.7 times faster than the Galaxy S III at the same two-month point in its life. Samsung previously announced they had sold 10 million units around a month ago, so we're looking at around 10 million units per month which is nothing to complain about. If Samsung can continue to sell at this rate, the Galaxy S4 could be their most popular smartphone ever.
