Apple Inc and Samsung Electronics Co Ltd continue to struggle as they find their place in India. In a new data released by a market intelligence firm, OnePlus has been revealed the top-selling premium mobile phone vendor in one of the world's fastest-growing economies.

Chinese smartphone manufacturer OnePlus has secured the top spot in a new market share analytics report by International Data Corporation (IDC) outlining the top performing phone manufacturers in India in terms of saleability. Despite the iPhone 7 and Galaxy S8 scoring the most impressive rave reviews, Shenzhen-based OnePlus was able to outdo the world's biggest tech giants.

In the second quarter, OnePlus claims 57 per cent market share for online smartphone sales in India. Apple comes second with 38 per cent share, while Samsung ranks third with mere 4 per cent share. Other brands occupy the remaining 1 per cent share.

The parameter of the premium landscape in the analysis is set for devices that cost not lower than US$400. The IDC data does not include offline sales.

OnePlus has been pushing its advertising strategy in India where its billboards fill the cities, which according to Tech in Asia, seems to be the driving force in the surge of online shopping for mobile phones.

In June, OnePlus released its new flagship smartphone, the OnePlus 5, with a base price of US$479. It runs on premium specifications and features, such as dual-camera system and Snapdragon 835 processor that can only be found in high-end cameras of Apple and Samsung.
