Problems solved by technology

However, due to the limited volume of mobile phone terminals and in order to expand the area of ​​the display screen, almost all mobile phone manufacturers design the camera on the top of the mobile phone. This design defect makes it difficult for users to focus on the camera when making video calls through the camera. Look at the face of the other party displayed on the screen, but cannot focus on the camera while looking at the screen, resulting in the inability to make eye contact when the two parties are in a video call

And, because the user is usually accustomed to looking down at the camera when using a mobile phone, the camera is always at an angle of looking up to shoot a face, causing the face images displayed on the screen of the mobile phone to be in a state of looking up, which makes the user feel uncomfortable when making a video call. Less than a good visual experience
