Global smartphone sales volume will maintain low single digit growth rate in 2018 and 2019, due to extended smartphone replacement cycle, higher smartphone prices, industry consolidation, shrinking China market, as well as economic headwinds / uncertainties etc. We expect the growth rate will slightly pick up from 2020 onwards mainly driven by 5G and new hardware innovations. Worldwide smartphone sales volumes will steadily expand by +25% from 2018 to 2023. Asia Pacific remains as the biggest region, followed by North America. The three largest smartphone countries by far in the next five years will be China, India and the USA, due to their massive populations.

Almost every major country worldwide is covered, including the United States, China, India, Indonesia, Japan, South Korea, Russia, Brazil, Mexico, South Africa, Saudi Arabia, UK, Germany, France, Italy and Spain.
