Global mobile phone market volume grew sequentially but declined year-on-year in the first quarter of 2019, reaching 421.6 million units. Of the total mobile phones shipped, 329.3 million were smartphones, down both sequentially and year-on-year. The decline is mainly attributed to the fact that mobile phone markets in North America, Europe, and China have been saturate and the prices of new models have been relatively high compare to the past years. On top of that, the number of new models launched in the fourth quarter of 2018 was relatively few. Due to the relocation of productionfacilities as result of the US-China trade war, the global smartphone market volume is estimated to decline in the second and third quarters this year.
