HTC was ready to show its upcoming One X smartphone at the Barcelona Mobile World Congress. The HTC One X is the flagship member of HTC's new One family of smartphones. It features a 4.7-inch, 720p HD display and is powered by a quad-core NVIDIA Tegra 3 processor clocked at 1.5GHz. It is constructed of unibody polycarbonate, and has an 8 megapixel camera with 1080p HD video capture.

The One X runs Android 4.0 Ice Cream Sandwich with HTC's new Sense 4.0 interface with ImageSense camera features. HTC will launch the One X globally in April. A version with LTE and Qualcomm's Snapdragon S4 dual-core processor will be headed to AT&T in the U.S.

Alongside the new flagship One X, HTC was also showing off its just-announced One S at MWC 2012. The One S has the same unibody type of construction as the One X, but instead of polycarbonate it is made of aluminum. The finish of the phone features an ultra-matte black Ceramic Metal surface that is the result of a microarc oxidation process. This gives the phone a surprising amount of grip when it is in your hand, though it still attracts fingerprints like other matte finishes. The One S is extremely thin and light too, and the slight curvature to the body fits your hand better than say Samsung's flat, thin smartphones.

HTC also revealed the entry-level One V which has a retro unibody design that harkens back the to the Legend from 2010 and Hero from 2009. The One V is certainly lower-end than the One X and One S, and it lacks the "wow" factor that the other two have when held in your hand. Its display is noticeably smaller, at 3.7-inches, and the chassis is considerably thicker than the others.
