Strategy Analytics predicts global smartphone shipments will maintain the downturn track and the volume will decline -1% YoY in 2019. Under the worst scenario, we expect the market will maintain the downturn trajectory and fall -3% YoY in 2020. Under the best case, we expect the market will rebound by +3% YoY in 2020. Samsung will maintain the leadership in Europe, Central Latin America and Africa Middle East, while Apple will remain the top position in North America. Huawei will top the chart and see a big growth in Asia Pacific region this and next year, mainly thanks to the resurgence in home market. However, we expect Huawei will significantly lose ground in overseas markets under the US ban. OPPO, vivo and Xiaomi would see headwinds in home market in the following quarters.
