U.S. tech giant Apple had a sour first quarter in China's mobile market. The country's top-four handset makers - Huawei, Vivo, Oppo and Xiaomi - secured a 53-percent combined market share.
Statistics released by Counterpoint Research shows iPhone shipments in May dropped by 1.2 percent year on year in the Chinese mainland, while its sales in Greater China fell 26 percent in the first quarter.
Meanwhile, competition between China's four largest smart phone makers is intensifying, as they scramble for a bigger share of the world's largest smart phone market.
