Q：How to use the split-screen function
A：1. Both apps that need to be used in split-screen mode must be running, meaning they are running in the background.
2. Clicking the menu button at the bottom of the screen will show all the apps running in the background. Click the icon at the top of the view of one of the apps you want to use in split-screen mode, select "Split Screen" from the pop-up options, and then select the other app you want to use in split-screen mode.
3. The separator between the two app interfaces in split-screen mode can be dragged left or right (or up and down when splitting vertically). Drag it to the very edge to exit split-screen mode (or press the back button on the navigation bar to exit split-screen mode).
