Chinese Brands Challenge Samsung and Apple
Smartphone Market
Among the top 5, Apple was the only vendor whose sales didn’t grow by at least 10 percent compared to last year’s September quarter. This can largely be attributed to the fact that Apple’s major smartphone release of the year, the iPhone X, wasn’t available until October as opposed to last year’s iPhone 7, which made its debut in September and thus contributed to Q3 sales.
Despite an 11 percent decline in sales compared to Q3 2016, Greater China is still the largest smartphone market in the world. Accounting for 27.9 percent of sales, the Chinese market is more than twice as large as the North American market in terms of unit sales.
