Apple is aggressive planing to grow its iPhone and iPad business in India, one of the world's fastest growing market for smart devices, and the company is re-looking at its distribution landscape and redefining its customer segments.
According to CyberMedia Research, the iPhone maker has emerged as the largest 4G LTE device vendor in India with a market share of 45 per cent in October-December 2014.
The research firm said over a million LTE devices -- including smartphones, tablets and data cards -- were shipped to the Indian market in the fourth quarter of 2014, marking the "coming of age" of the 4G devices.
