What is the effect of turning on the focus mode?

After turning on the focus mode, your mobile phone will enter a new state.

Turn on focus mode to help you handle tasks more effectively and avoid being disturbed by unnecessary notifications. The mobile phone will only receive allowed notifications, all other applications and notifications will be muted, and the status will be displayed in the chat conversation. However, it should be noted that after the focus mode is turned on, other important notices such as phone calls and text messages cannot be received in time, so please ensure that the focus mode can be turned off or exceptions can be set if necessary.
