New Delhi: Global smartphone sales are likely to grow at a lower rate of 11.3% this year as compared to 27.6% in 2014, impacted by a slower pace of growth in the Chinese market, research firm IDC said. While the overall growth will continue to slow, many markets, especially India, will experience robust growth in 2015 and beyond with global shipment volumes forecast to reach 1.9 billion units annually by 2019, IDC said. According to IDC, 1.44 billion smartphones are expected to be shipped globally in 2015. However, India’s share is estimated to grow from 7.61 per cent in 2015 to 13.29 per cent in 2019, IDC said.
