One of the year's most-anticipated smartphones, the Samsung Galaxy S3, has been subject to rumours since its younger brother's launch, giving us a good idea what to expect ahead of its unveiling at Mobile World Congress.
he phone, if the rumours are in fact accurate, will be the firm's most impressive handset yet. Lurking under the hood of its super-slim body you'll reportedly find a "1.5GHz or 1.6GHz quad-core" processor, which will deliver over double the speed of the Samsung Galaxy S2. These eye-popping innards will come paired, rightfully so, with the most-up-to date version of Google's mobile software: Android 4.0 Ice Cream Sandwich. This will equip the phone with a bunch of brand-new features, including Android Beam NFC support, Face Unlock functionality and a much-improved Android web browser.

This ICS operating system, as per, will come skinned in Samsung's TouchWiz UI, and we're expecting to see a yet-unannounced version of the custom interface. Still, as with its predecessors, this will dress the phone's multiple home screens with Samsung Hubs, social networking integration and plenty of customisation options.

Things sound just as impressive on the hardware front. Like the Samsung Galaxy Nexus, the S3 is rumoured to pack a whopping 4.65-inch Super AMOLED touchscreen, complete with a 1280 x 720 HD resolution. This'll deliver the perfect platform for displaying photos shot on the mooted 12 megapixel rear-facing camera, which will be capable of shooting 1080p HD video.
ther rumoured specifications include; a yet-unspecified front-facing camera, 32GB of built-in storage, NFC technology, HSDPA and WiFi connectivity, and support for 4G speeds over in the States.

The Samsung Galaxy S3 is expected to get the official nod ahead of MWC on February 26, with an April release to follow.
