HTC has recently launched in China the One XC Android smartphone – a variant of the flagship One X powered by Qualcomm’s Snapdragon S4 chip.

The HTC One XC carries quad-core processors clocked at 1.5GHz, has 1GB of RAM, 4.7-inch display with 1280×720 resolution, 8 megapixel camera and runs Android 4.0 Ice Cream Sandwich. It also sports a different look with a black body with gold trim.
Overall, the One XC is similar to the One X but the placement of the Snapdragon S4 chipset enables the One XC to go head-to-head with the Xiaomi Mi-2 which also carries the same chipset.

Looks like the HTC One XC is exclusive to the Chinese market and is priced at $310.
