Samsung's Galaxy S4 has already proved a huge hit in the market, with millions sold since it was launched to market in April.
Since then the firm has unveiled several variants of the device, such as the Zoom for a better camera, and the Active, which is designed for use in tough environments. The Active boasts physical buttons on the front to make it easier to operate while wearing gloves and conforms to the IP67 rating for dust and water protection.
This should ensure that dust particles are unable to penetrate inside the device and that it can survive submersion in water at a depth of one metre for 30 minutes. The earphone jack is also water resistant and the camera lens works underwater.
Specs-wise, the device is almost identical to the standard S4, with a 1.9GHz quad-core processor and a 5in screen with screen quality of 443ppi. You can also read our full review of the Samsung Galaxy S Active.
