HTC has a rather large booth at CTIA 2012 and most of it is dedicated to advertising the new features of its One line of smartphones. The company definitely wants to be seen and heard here at the show, in fact, even our badges have “HTC One” written on the back of them. We swung by the booth to see if there was anything new and were pleased to find a step-by-step guide to how HTC builds its super strong oxidized HTC One S shell. Unfortunately, T-Mobile launched the gradient version of the phone and not the oxidized matte black model, but the whole method is incredible interesting. HTC puts the metal through an oxidization process and, since we’re not materials scientists we’ll let the photo gallery and accompanying captions below speak for itself.
