The Samsung Galaxy S4 has finally landed with enough new features, including a brighter screen and an Xperia Z-rivalling camera, making it a worthy alternative to the iPhone 5 and the HTC One.

With a bigger 5-inch display to protect and a slender new design to keep scratch and dent-free, buying a nice cover for your Samsung Galaxy S4 will surely be one of the first things on your new phone to-do list, along with adding mum's number to your address book and setting up Facebook.
