The Samsung Galaxy S4 Active is a waterproof, drop proof and dust proof spinoff to the S4. A revised design gives this 5-inch phone IP67 certification. The S4 Active’s design is slimmer than we had expected. Measuring in at 9.1mm thick it is 1.2mm chunkier than its more high-profile sibling yet feels just as streamlined and svelte. On top of this, the added bulk and protection make it feel considerably more sturdy. It features trio of physical Android controls as opposed to the usual touch based options found on the original S4. This allows it to be used in more challenging conditions such as when caked in mud or underwater. The Samsung Galaxy S4 Active’s screen is a slight deviation from that on the S4 but equally impressive. An LCD option instead of Super AMOLED panel, it is still of the 5-inch variety and impresses from the off thanks to a 1080p Full HD resolution and stunningly sharp 441 pixels-per-inch image density. It is a bright, pleasing offering with sharp colours and extremely detailed text and image production. On first impressions, the performance of the Samsung Galaxy S4 Active felt on par with the S4. Featuring the same 1.9GHz quad-core processor as its big brother, it is also bestowed with 2GB of RAM and Google’s Android 4.2.2 Jelly Bean OS skinned with the TouchWiz UI. The Samsung Galaxy S4 Active is possibly our favourite of the S4 spinoffs. It poses the question what could have the S4 been like with a slightly studier frame and, we expect, gives a nod to next-year’s flagship model.
