Samsung's Galaxy S4 smartphone has sold more than 10 million units around the world less than one month after being released, making it the fastest-selling Android phone in history.
The new flagship smartphone, launched globally on April 27, is estimated to have sold at a rate of four units per second, according to the company, and has sold at twice the rate its rival, the HTC One.
The S4's predecessor, the Galaxy S3, previously held the title for the fast-selling Android smartphone after reaching the 10 million mark after 50 days on sale in 2012. Before that, the Galaxy S2 and Galaxy S took five and seven months respectively to reach the same goal.
"On behalf of Samsung, I would like to thank the millions of customers around the world who have chosen the Samsung GALAXY S4," said JK Shin, chief executive and president of IT and mobile communications at Samsung. "At Samsung we'll continue to pursue innovation inspired by and for people."
An anonymous Samsung executive told South Korean newspaper The Chosun Ilbo last week that sales had surpassed six million in the first two weeks after launch.
Meanwhile, an unnamed HTC executive told The Wall Street Journal that the HTC One, seen by industry commentators as a rival to Samsung's S4, has sold five million units since its launch, which occurred about the same time as the S4, meaning Samsung has doubled the sales of its HTC rival.
Both Samsung and HTC have confirmed they will release a version of their new smartphones running the default version of Google's Android mobile operating system, rather than the ones currently customised with Samsung or HTC apps built in.
Samsung also confirmed that the Galaxy S4 will be made available in four new colours later this year: red, blue, purple and brown. The smartphone was available in black and white at launch.
