2. Click My to slide down to the preset theme and select the preset theme you like.

3. Click the application below.

Note: Switching the default theme cannot be solved. You can follow these steps:

1. Try whether the mobile phone can work normally after restarting.

2. Horizontal screen can be pulled down, but vertical screen can't: Please open an application that can be used for horizontal screen, such as the glory of the king, and pull down the status bar.

3. Pull down to open the search box: Sliding the home screen down from the middle of the screen will open the global search box, and pulling down at the top of the screen will open the status bar. Please pull down from the top.

4. You can't pull down the screen lock interface during the call: In order to avoid misoperation of the shortcut switch, it is no longer allowed to pull down the status bar in the screen lock interface and during the call. You can drop down the status bar after the screen lock interface is unlocked.
