Ah, the Galaxy S4 Active: it's like the regular Galaxy S4 but, you know, more rugged. It's actually not a truly rugged device, since it hasn't been built to meet military specifications, but it's certainly designed to stand up to slightly more abuse than its non-Active namesake. It is able to survive in up to a meter of water for 30 minutes and sensitive areas, like the micro-USB port on the bottom edge, are protected by rubber flaps. The beefed-up build adds some weight, about three-quarters of an ounce, and we actually find it quite welcome. Where many Samsung handsets can often feel cheap, plasticky and are lighter than they look, the S4 Active actually has a pleasant and natural heft to it. The weight makes the phone feel less fragile than the regular S4 and also delivers a better balance in the hand. We grabbed some hands-on time with it at Samsung's London event, so dive past the break for our impressions.
