The Samsung Galaxy S4 runs on the easy to use and widely popular Android operating system. The Galaxy S4 includes a vivid Full HD 5" display for pin-sharp images, rich colours and flicker-free video that you want, the S4 screen is certainly going to impress while brining Web pages to life. The Super AMOLED display handles colours and blacks just as well as we have come to expect, even in bright sunlight. The touch-free navigation enables you to view photos and files with just a wave of your hand.

There are so many cool, useful, and sometimes scarily clever tools included with this phone including S Planner, S Memo, S Voice and now a handy way to keep in shape with S Health. This app allows you to input your personal data and will then track your food and calorie intake. There is even a sport band available which can sync to the app and track your daily exercise. Another useful tool is the translator. This lets you speak into the phone and have your words translated into a number of different languages on the go.

The 13 megapixel camera in the Samsung Galaxy S4 16GB Demo was just about the highest resolution camera found in any smartphone at the time of release and today is still regarded as a high quality camera. Whilst Burst Mode and HDR mode help you to grab the best pictures possible, new additions such as Dual Shot and Sound & Shot add fun to your photos. Dual Shot lets you take a photo with the main camera and then superimpose your face over the top of it, whilst Sound & Shot enables you to attach a short audio clip to a photo, which then plays when the photo is viewed.
