Around 15 million smartphone of Xiaomi was sold in Chinese market during the second quarter, more than a three-fold surge from a year earlier, revealed market research of a company.

The sale of Samsung's China smartphone decreased to 13.2 million units from 15.5 million during April-June last year.

Lenovo trailed Samsung by a margin of 2 million units.

According to market research of a company, China was the world's largest smartphone market during the second quarter, with nearly four in every 10 smartphones sold there.

Samsung reported last week its lowest quarterly profit in two years for the second quarter, partly blaming a slowdown of cheap smartphone sales in China.

Samsung said it faced higher competition from local brands and weaker demand for its 3G handsets as Chinese consumers shifted to 4G smartphones.

Last week, another market research firm Strategy Analytics said Xiaomi became the world's fifth-largest smartphone vendor for the first time in the second quarter, surpassing LG Electronics Inc.
