Android devices dominated smartphone sales in the second quarter of 2016, with devices running Google's popular operating system accounting for 86.2% of the market share. Apple devices, however, saw a downward trend in Q2 sales, recording a 7.7% drop, according to a report by IT research and advisory firm Gartner.

Global sales of smartphones rose to 344 million units in the second quarter, marking a 4.3% jump as compared to that in the corresponding period last year. Five of the world’s top 10 phone vendors – Huawei, Oppo, Xiaomi, BBK Communication Equipment and Samsung – all showed growth. Samsung led with 76,743 units, followed by Apple with 44,395 units and Chinese brand Huawei with 30,670.

Overall sales, however, contracted by 0.5%, the report added. According to Anshul Gupta, research director at Gartner, demand for "premium smartphones" drop in the second quarter as consumers wait for the launch of new hardware in the second half of the year.

Moreover, Apple's sales has been on a decline in the United States – its biggest market – and Western Europe. But it has been even worse in Asia where sales plummeted a massive 26%. However, in Eurasia, Sub-Saharan Africa and Eastern Europe, Apple saw a 95% year-on-year growth, according to the Gartner.
