In 2018，the global mobile phone market declined slightly as the Chinese domestic mobile phone market continued to experience negative growth. Yet at the same time，the global market share of domestic brands further increased. Bezel-less screen，AI chips，multi-camera configuration，biometric recognition，fast charging，gaming for mobile phones and other technologies became the focus of the smartphone market in China. Mobile smart terminal products were increasingly rich in form. Wearable devices，Internet of Things terminals，and vehicle-mounted wireless terminals were rapidly developing. With the arrival of 5G，the smart terminals will present a trend of diversification in product form and differentiation in terms of technical functions in all three major usage scenarios.
