How does Xiaomi do not disturb mode treat missed calls?

Look for missed calls in the address book.

Xiaomi mobile phone can still receive incoming SMS normally after the Do Not Disturb mode is turned on.

When the "Do Not Disturb" mode is turned on, incoming calls and text messages will not ring or vibrate. When the phone is locked, it will not wake up. You can choose to turn on the timing and do not disturb mode, or you can choose to set the number to ring normally.
