Smartphone sales set for bigger hit following more curbs in Delhi, Mumbai Representative Image Synopsis For now, the lockdowns in Mumbai and Delhi would hurt the premium segment of devices more, a segment that has been the fastest growing category—between 70% and 100%—for the past three quarters. Smartphone sales are set to take a sharper hit in the coming weeks with restrictions being announced in Delhi as well, adding to Mumbai, the top two metros accounting for 20% of India’s overall smartphone market. But market trackers say the bigger fear is of a lockdown in Noida, which would lead to a far bigger negative impact on the industry, as the region accounts for 60% of the smartphone production in India.
