Huawei's mobile phone is very powerful. It can run two apps at the same time while separating the screens. There are four ways to split the screens. Let's take Huawei's p30 mobile phone as an example!
First, make sure that the split screen gesture of the phone is turned on. Operations: Settings - Auxiliary Functions - Quick Start and Gesture.
Enter the shortcut startup and gesture, and then select split screen.
After the above operations, the split screen shortcut gesture has been enabled. Let's take a look at the first method: after opening an application that supports split screen, three fingers slide up from the screen to start split screen, and the slide up operation should not start from the bottom edge of the screen.
The split screen operation has been enabled. The following part can be used to open the app that supports split screen operation.
The second method: After opening an application that supports split screen, press and hold the screen with a single finger joint slightly to ensure that the finger joint does not leave the screen, and then drag the finger joint slightly to slide the screen to the right to start split screen. And the split screen scale can be adjusted. Click the small dot in the circle in the figure and drag it up and down to change the scale.
The third method: click the box key to open the split screen when the three key navigation in the screen is enabled.
The fourth method: start the recently opened program, enter the background, select the app to split screen, click the split screen button in the upper right corner to start split screen.
