After yesterday's hands-on with the Optimus G we had the opportunity to sit down with Dr. Henry Nho, LG Mobile's Chief Research Engineer, to discuss the technology behind the company's beautiful new flagship smartphone. We talked about the challenges his team encountered while designing the world's first handset to feature Qualcomm's 1.5GHz quad-core Snapdragon S4 Pro SoC -- including issues such as power and thermal management. Making the handset 8.45mm (0.33-inch) thin was another major engineering feat made possible by the Zerogap Touch display, sealed 2100mAh Li-polymer battery and compact 13-megapixel camera module.
