The Samsung Galaxy S II is the phone the Korean firm deems the successor to its best smartphone so far. And with a 1.2GHz processor, super-slim chassis and feather-light innards, it’s easy to see why.

The dual-core race is set to heat up massively over the next few months, with the LG Optimus 2X already released, and the Motorola Atrix, HTC Sensation and iPhone 5 or iPhone 4S all set to bring the tech to market too.The Samsung Galaxy S2 is almost impossibly thin when you pick it up – dimensions of 125.3 x 66.1 x 8.5mm mean it’s one of the thinnest smartphones on the market at the moment, rivalling the likes of the iPhone 4 and Sony Ericsson Xperia Arc for the title.

The 3.5mm headphone jack lives on the top of the phone, bucking the lower placement on other 4.3-inch screen phones, and the microUSB slot (which also doubles as an HDMI out port) lives on the bottom.

The only other element of note is the 8.1MP camera with single LED flash on the rear – it’s slightly raised, but not so much that it disrupts the Galaxy S2 when you’re placing it on a table, thanks to a rear lip to help you hold the phone.
