Why is oppo a full screen? Happy birthday.

Oppo set full-screen happy birthday steps:

1. Turn on the holiday wallpaper switch in Settings-Display-Holiday Wallpaper; 2. In Settings-Security Service/Security Privacy-Screen Locking-Set Screen Locking Mode-Optional Sliding/Face/Pattern/Password Unlocking (take pattern unlocking as an example here); 3. After the above steps are completed, the setting is successful. For example, today is a birthday, so when the lock screen reaches 0 o'clock today, the lock screen wallpaper displayed under the lock screen bright screen will be a happy birthday wallpaper, and the expression pattern of happy birthday atmosphere will be dropped on it.
