New Delhi, Feb 14: Despite the government’s continuous push to help domestic smartphone manufacturers, Chi-based vendors are thriving and their collective market share has reached a massive 53 per cent in 2017 from 34 percent a year ago, Intertiol Data Corporation (IDC) has said. “The untapped demand in the lower-tier cities remains the key attraction for Chi-based brands to explore the growth trajectory in India,” said Jaipal Singh, Senior Market Alyst, IDC India. Their strength in their home market of Chi and weakening position of local players has helped some of these Chi-based players to solidify their operations in India,” he added.
