Shenzhen audio became Africa’s largest sales of the smartphone company. It sold more than 50 million handsets in Africa in the first half of the year, mainly with a physical keyboard, plus 11 million smartphones. Globally, the voice is ranked fourth on handset sales, after Samsung, Apple and Huawei, but by sales, it is only the 13th-largest handset maker. The tone took an unusual path, ignoring the Chinese market, setting up sales networks in sub-Saharan Africa and trying to adapt low-cost handsets to local tastes. It is now targeting the South Asian market, moving its manufacturing operations out of China, building a factory in India, and establishing an “industrial park” in Ethiopia, where a number of handsets have been made.
