How does Apple's mobile phone turn the icon sideways?

First, please click to open the "Settings" application on the Apple 6 screen, as shown in the figure.

In the list of settings, find the column "Display and brightness" and click Enter.

Next, under the list of display and brightness, click the column of "display mode", as shown in the figure below.

Then in the display mode, please select "Standard Mode" and click the "Settings" button. If you are currently in standard mode, you don't need to set it.

When resetting the display mode, you need to restart the system to adapt, and then click the restart button that pops up at the bottom.

After the restart, we can try to experience the horizontal screen operation. The home screen supports landscape screen, weather, stock market and other applications. As long as the application of landscape screen is supported, if you turn the phone sideways, it will automatically switch to split screen mode.
