This light, polymer-built case hugs your handset and shows off a matt and glossy pixel finish that will make the back of your smartphone look a bit like a minesweeper board. A raised bezel will help keep the screen out of harm when lying flat, while rubberised button covers should add another layer of protection.
The clue is in the name - this hard shell case is all about keeping your S3 in one piece using a silicone inner and durable polycarbonate shell to sure up the defence and make it easier to keep hold of. If you are a heavy-handed phone user or like to take your phone hiking, this case is designed for you.
This official Samsung case comes in an array of colours and replaces the battery cover and guards the AMOLED display against scratches and dirt. By covering the whole of the front, it stops you from accidentally pressing buttons or swiping, and with an NFC chip built in, it means you can still share images and videos by tapping it against another S3.
Made up of a polymer and carbon fibre backplate, the Atom also sports rugged, robust corners to absorb impact and make it more comfortable to hold. Buttons are moulded over and integrated into the case, while a speaker port means the sweet S3 sound doesn't get trapped.
20. Otterbox Defender Series - US$50 (around £32/AU$48.50)

Providing some back-up juice for your Samsung smartphone, the 2,000mAh charging capacity of this case will bump up the phone's power, with a row of LED lights notifying you how much battery you have left. Clipping onto the back and bumper, the OffGrid is made from Plextonium to fend off dents and scratches to the body, and is housed in surprisingly slim body.
If smartphone radiation is a concern, this snap-on case has been designed with an antenna system to deflect radiation away from your head when you are chatting. But that's not the only trick up its sleeve. It can also increase talk time battery life, improve signal strength and won't get in the way of any NFC transactions.
A slim solution to make sure the S3 makes it through the day, the 2,300mAh capacity case will deliver an extra 32 hours of audio or nine hours of web browsing. It can charge both smartphone and case at the same time, with LED notification lights displaying progress. Plus NFC and S-Beam support means you can still enjoy one-touch sharing.
