Our very own Matt Brian was on the ground in London as Samsung unveiled its brand new Galaxy S III, and I have to say that it’s quite beautiful. The phone sounds like a powerhouse, as expected, with some impressive specs: The phone features a 4.8-inch Super AMOLED screen, measures 136mm x 70mm and has a 1280×720 HD display, all powered by a 1.4 GHz Exynos 4 Quad processor. Matt went hands-on with the latest device from Samsung, which should hit stores by the end of summer. (via Hands-on With The Samsung Galaxy S III [pics])
