China's smartphone shipments fell 4.3% to 66 million ‌units in the second quarter from a year ‌earlier, as many manufacturers hiked prices to reflect rising memory and ​component costs, research firm IDC said on Tuesday. It was the fifth straight quarterly decline, and first-half shipments were down 4.2% from a year earlier. Huawei Technologies and Apple were ‌the only vendors ⁠to post growth in the quarter, with shipments up 19.4% and 24.4%, respectively.
