Samsung Galaxy S4 review and specifications.

Samsung Galaxy S4 looks almost similar to its predecessor S3. Unlike IPhone and most HTC phones, it is made of plastic so it's a relatively light device.

Another thing about this device is that it's edges are flat and straight instead of round ones.

Running on Android OS , v4.2.2 (Jelly
Bean), it is powered by Samsung's latest Exynos 5 Octa 5410 Octa
core processor and a 2GB RAM. Its screen is a 5 inch 1080p display with a 13MP Camera. Most interesting is the 'floating touch' display which means you can operate the screen without touching it.
