KOREAN PHONE MAKER Samsung announced its Galaxy S4 smartphone at a bizarre press event in New York on 14 March, wooing the crowd at Radio City Music Hall with its hardware upgrades and innovative software features.
Since, it has made its debut in the UK and other countries, and Samsung announced in May that it has already flown past 10 million sales. If analyst predictions are anything to go by, this number may increase to 80 million before 2013 is up.
Because of these bumper sales, Samsung has since announced a handful of new Galaxy S4 models, which will be available in red, brown and purple.
Of course, these incoming model will feature the same specs as the original Galaxy S4, including a 5in touchscreen, nippy quad-core processor and 13MP rear-facing camera.
However, it's on the software side where things get really interesting, with Samsung equipping the phone with several features including Group Play and Smart Scroll, a quirky eye-scrolling feature that enables users to control webpages simply by moving their eyes. The Samsung Galaxy S4 also echoes Sony's Xperia lineup with its 'floating touch' display, which means users can operate the screen without touching it.
Not only has Samsung announced new colour versions, it has also announced the pint-sized Samsung Galaxy S4 Mini and the rugged Samsung Galaxy S4 Active.
