Why can I still hear CRBT after I leave you?

Because don't disturb is set for black people, it will ring normally, and there is no limit!

Because contacts who are not blacked out will always be prompted to get the bell, and those who are blacked out will not receive any information about the bell. This is the self-judgment function of the mobile phone, and judgment, understanding and analysis should be added. This situation can be adjusted and changed normally!
