Are you still worrying about forgetting to adjust the volume of your mobile phone, being startled by a sudden call at work, or being woken up by the phone when you sleep? The scene mode is a tool application that automatically adjusts the volume, ring mode, and screen brightness. You can customize any number of modes, and each mode can be set to automatically trigger at any time, so you don't have to worry about forgetting to set it again. (It is recommended to add desktop widgets to the desktop to avoid invalidation due to being killed by the mobile phone system)
