On Sunday at MWC, Huawei launched their three newest Android phones: The Ascend D Quad, Ascend D Quad XL and Ascend D1. The first two are running Huwaei's own custom quad-core chip, called the K3V2, which they claim is faster yet more energy efficient than the competition from NVIDIA and others. They claim it is the "world's fastest quad-core smartphone." Here's a breakdown of specs from their new flagship devices: Huwaei Ascend D Quad & Huawei Ascend D Quad XL - K3V2 quad-core 1.5GHz processor 4.5-inch 720P high definition touchscreen 8-megapixel rear-camera - 1080p full HD video 1.3-megapixel front-facing camera Android 4.0 Ice Cream Sandwich 1800mAh battery (The Ascend D quad XL has the same specs as the Ascend D Quad above except it comes with a hefty 2,500 mAh battery.) The Huawaei Ascend D1 is their mid-range/budget device, and although they didn't share much about it, we do know it comes with a 1.5GHz dual-core processor and a 1650mAh battery. Here are some launch details followed by the press release, "The Ascend D quad series will be available in China, Australia, Europe, Asia-Pacific, North and South America, and the Middle East in the second quarter of 2012, with the Ascend D1 to be made available in April."
