Pure-Gear Retro Game
On the front, this case just looks like any other, offering essential protection to the rim of the device. Turn it over however, and it's a completely different story.

This is a nice slim case that will protect from light bumps and scrapes - but Ted Baker is the star of the show here. The Autumn/Winter collection uses a natty chess board design, for those who are more than comfortable with their inner board game nerd.
Anymode Marvel Beamcase
These funky Marvel cases come in a variety of designs, featuring pretty much all of your favourite Marvel superheroes.

It's slim and unobstructive of ports too, good show.
Samsung S View
The official case for the Galaxy S4 looks much like the old flip cover the S3. This time, a letterbox cut-out at the top of the case displays part of the screen when the case is closed, so to speak. The phone recognises when the cover is on, and it displays important info - time, notifications, that sort of thing - at the top of the screen, so it is viewable through the letterbox apps.

If you want to ditch the wallet and keep receipt hording to a minimum, the polymer case has enough room in the back to hold three cards or store away an emergency fiver in the back. Available in a range of vibrant colours, there's also rubberized cover for Sleep/Wake and volume buttons to keep out the scratches.
The fashion choice of winter sport enthusiasts and surfers, the case with a trendy checked print is slim enough to not add extra bulk to your 7.9mm thick Samsung Galaxy S4 smartphone and also comes with a screen protector to add another layer of protection.

Samsung Flip cover
Another official case offering unveiled at the Samsung Galaxy S4 launch, the cover attaches itself to the back of your S4 the slender rubber bumper aims to guard your 5-inch 1080p screen from day-to-day damage and then can fold away when you want to get back to playing.

Crucially there's holes for the ports, headphone jack and that new 13-Megapixel camera to take full advantage of all those new snapping features.
