What is the focus mode of the mobile phone?

If you use a vivo phone, focus mode function:

You can avoid unnecessary notification interruption in Do Not Disturb, work, sleep and personal scenes. Incoming calls, messages and notifications will be muted during power-on and the phone will not wake up when the screen is turned off. Incoming calls, text messages and notifications will be reminded normally.

Opening method: Enter the setting-sound and vibration/sound, vibration and silent key-focus mode, and set the "Do not disturb, work, sleep and personal" mode as required. Click "Auto-Open" on the page to automatically open this function at regular intervals.

Note: Because the configuration and functions of each model are different, if this option is not available, it means that this model is not supported.
