What is a physical key?

In modern society, people generally use touch screen buttons. Do you know what a physical key is? Next, let me tell you what a physical key is.

Physical key meaning

In the past, when there was no big-screen mobile phone, physical keys were rarely said. After a large-screen mobile phone is equipped with a capacitive touch screen, it has the name of a virtual key, and all keys are divided into physical keys and virtual keys. Physical keys are physical keys. Loose physical keys mean poor contact and failure of keys.

Advantages of physical keys:

1) The tactile sensation of virtual keys is almost the same as that of capacitive keys, even more sensitive than the latter;

2) Not as fragile as physical keys;

3) Don't be distracted by the off-screen area;

4) Support rich custom settings, including the length and width of key bars, the number, sequence and function mapping of buttons, the size, style and color of button icons, etc.

5) It can realize backward and immersion modes, and support automatic hiding and gesture calling;

6) Support translucent system UI and allow translucent system bar (status bar+key bar);

7) Allow the background color of the system bar and the superimposed color of the small icon to change automatically with the applied theme color.

Shortcomings and improvements of physical keys;

1) Touch is not as good as physical buttons. But at present, it is the world of capacitive buttons. Looking forward to the popularity of touch-sensitive display screens.

2) Occupy valuable exhibition area. However, Android already supports the real full-screen mode, which is on call.

3) The dark status bar and key bar divide the screen into three parts, which separates the sense of visual unity.
