What does it mean that there is a moon sign on the mobile phone? What's the use of the moon constellation on the mobile phone?

If you use a vivo phone, the moon icon in the status bar indicates that "do not disturb mode" has been turned on. When the Do Not Disturb mode is turned on, all incoming calls, messages and software notifications will be muted except those who are allowed to disturb. You can also set a time period to automatically turn on the Do Not Disturb mode.

Setting path: Settings-Sound and vibration/sound, vibration and mute keys/sound-Do not disturb mode/focus mode.
