China's Huawei Technologies Co is set to be the fastest-growing major smartphone vendor this year, analysts said, boosting its drive upmarket to challenge industry giants Samsung Electronics Co and Apple Inc. The upbeat view came after Huawei, the world's third-biggest smartphone supplier by volume, on Tuesday said third-quarter global smartphone shipments jumped 63 pct year-on-year to 27.4 million handsets. Higher-end device sales also grew, a key target for Huawei as it seeks to shed its budget supplier image.
