For years, smartphone designs have been trending towards fuller screens. The biggest innovation of this phone design is the hidden front camera beneath the screen. It also integrates other components including under-display sound, an under-display light sensor, and an under-display fingerprint sensor. All of these components are blended beautifully into a 6.92-inch screen, giving consumers a perfect full-screen experience. The 3D curved glass back gives Axon 20 a soft and graceful feeling in the hand. For special user scenarios, Axon 20 possesses a high-speed train mode and an elevator mode with the latest 5G communication and super PDS antenna technology.
