Not exactly the best-kept secret in the mobile world, Samsung has launched the Samsung Galaxy S II, a slimline device that packs Android 2.3 and a premium set of features to match those eye-catching looks.Significantly thinner than the iPhone (would you believe), the all-new Galaxy packs a 4.27-inch 800 x 480 Super AMOLED Plus display, a full-featured (think mid-range compact) 8-megapixel primary camera that's capable of shooting video in 1080p HD, while a 2-megapixel camera takes care of the video calling side of things. Under the bonnet is a dual-core 1GHz Samsung chip, with 1GB of RAM keeping everything running along smoothly.Other features of note include a choice of 16GB and 32GB of built-in storage, high-speed 3G, Wi-Fi and interestingly, Bluetooth 3.0+HS, for the connectivity, along with Wi-Fi Direct to connect to wireless-enabled PCs and printers, plus NFC for those contactless payments - certain to be big news this year and next. Also listed is an accelerometer, 3-axis gyroscopic sensor, light sensor, digital compass and proximity sensor if any of those are important to you, plus, of course, that all-important GPS.That's before we talk about built-in business apps and software for work and for play, the latter in the form of separate hubs for Social, Readers, Game and Music. I think you've guessed what they cover, but just to clarify, Social brings all your social networks and messages together, Readers covers ebooks, specifically from Samsung's catalogue of up to 2.2 million books (along with papers and periodicals), Games allows easy download and access to mobile games from Gameloft, while music is your direct hook-up to 7digital. There's also the Samsung Live Panel for even more content management, specifically for customising your homescreen with information from feeds and real-time apps.When? Which network? Not clear as yet, but we would guess at a spring / early summer launch and just about every network wanting a piece of the Samsung Galaxy S II action. We'll confirm as soon as we get details.
