How to use 3D Ultrasonic Fingerprint of Galaxy S10 series

​A bunch of pioneers said that the fingerprints under the ultrasonic screen were overturned. In fact, they did not know how to use the ultrasonic fingerprints. The optical fingerprints must be pressed by the entire finger. The ultrasonic fingerprints are completely wrong here. Because the ultrasonic acquisition is the fingerprint 3D information, if you press the fingerprint to force the stereo deformation, it will affect the recognition accuracy. 

In theory, the fingerprint on the ultrasonic screen can be unlocked by air. It is only a mistake to confirm the touch screen. You only need to tap the identification area and “tell” the sensor. I want to unlock it now. 

The problem is coming. Some people think that it is not easy to use. I think it is the way they use it. 

Let’s take a look at my experience video, the exploration of optical screen fingerprint recognitio.
