The Samsung Galaxy S4 Active is a durable phone that is IP67 certified which means the casing is sealed against dust and water ingress. This tough phone has many of the same features of the original S4 packed into its tough shell including Smart Stay which keeps the screen illuminated for as long as you look at it. The large 5-inch touchscreen display also includes Smart Scroll which detects when you have finished reading to the bottom of the page and automatically scrolls the text for you. Android 4.2.2 delivers an array of Google apps and Google Play is on hand for more to download whilst Samsung have added some of their own features too. S Health and S Voice Drive are on board and the quad-core processor delivers impressive power for multitasking such as using S Health to monitor your exercise activity whilst listening to music. 3.5G, Wi-Fi and GPS are on board as well as NFC and there is a front facing 2-megapixel camera for taking self-portraits or video chatting. The 8-megapixel camera on the back includes a number of nifty extras including the ability to record sound with your photos and dual camera mode which takes images from both cameras at the same time. The waterproof properties of the phone also mean you can use the phone to take underwater photos and social network integration lets you share them easily too.
