In India, Russia and Brazil, the older types of cellphone are still the most popular.
– In India, 80 percent of phone users own an old-style feature phone, and only 10 percent have a smartphone. In Brazil and Russia, feature phones account for roughly half the market.
– China is one emerging country where the smartphone is dominant, with 66 percent of the market. That is largely thanks to the plethora of cheap Android smartphones available there.
