Samsung Electronics said Thursday that global sales of its Galaxy S4 smartphones have surpassed the 10 million mark since its release in late April. Launched globally on April 27, the phone is estimated to be selling at a rate of four units per second.

The GALAXY S4 sets a new record for Samsung, generating sales quicker than any of its predecessors. Sales of the GALAXY S III reached the 10-million mark 50 days after its launch in 2012, while the GALAXY S II took five months and the GALAXY S seven months to reach the same milestone.

"On behalf of Samsung, I would like to thank the millions of customers around the world who have chosen the Samsung GALAXY S4. At Samsung we?ll continue to pursue innovation inspired by and for people," said JK Shin, CEO and President of the IT & Mobile Communications Division at Samsung Electronics.

The GALAXY S4 has a Full HD Super AMOLED display that showcases images on a 5-inch screen with 441ppi. Equipped with a rear 13MP camera, the GALAXY S4 also boasts a Dual Camera function that allows simultaneous use of both front and rear cameras. The GALAXY S4's new software features include Air View and Air Gesture for effortless tasks, while it also keeps users up-to-date with information about their health and wellbeing using S Health.

Samsung GALAXY S4 is available in more than 110 countries and will gradually be rolled out to a total of 155 countries.

Samsung is planning to introduce more color variations to meet various consumer tastes and preferences. In addition to the currently available White Mist and Black Forest, new color iterations will be added this summer, including Blue Arctic and Red Aurora, followed by Purple Mirage and Brown Autumn.
