On Sunday, HTC announced the One X at the company’s Mobile World Congress 2012 press conference. The handset features a quad-core 1.5GHz NVIDIA Tegra 3 processor, a beautiful 4.6-inch 1,280 x 720-pixel high-definition Super LCD2 display, an amazing 8-megapixel rear camera, a 1.3-megapixel front facing camera, 1GB of RAM, 32GB of internal storage, Beats Audio and Sense 4 atop Android 4.0 Ice Cream Sandwich. During our hands-on time with the device the quad-core Tegra 3 processor was an absolute monster, and it helped the One X zip around ICS with no lag whatsoever. The One X is set to arrive on AT&T’s 4G LTE network by the end of April, however it will not include NVIDIA’s Tegra 3 chipset when it does. Instead, it will sport a dual-core Snapdragon S4 processor. As for the cause of the down-grade, the Tegra 3 chip wasn’t LTE-compatible when the handset entered production several months ago according to CNET.
