Don't know why everyone misses this big fish - Huawei Ascend D Quad XL in MWC 2012. "The fastest smartphone in the world" as Huawei claimed, and more 30% faster than Nvidia Tegra 3 based phones.
The quad-core processor is specially made by Huawei called the K3V2.
4.5-inch 720p display, 8 megapixel rear camera and 1.3-megapixel front-facing camera, Dolby 5.1 surround sound, a larger 2,500mAh battery, Android ICS.
