Huawei mobile phone sent two messages.

Turn off the notification of card 1 card 2 permission in the SMS settings, and turn on the Do Not Disturb mode in the SMS settings, not all of them are Do Not Disturb. Because I received two short messages, the first one is card 1 card 2 notification, and the second one is do not disturb notification. But if you turn off Do Not Disturb and turn on the notification of 1 card and 2 cards, you can't keep the information in the notification bar. After a few seconds, there will be no notification, but you can check it in the SMS. Therefore, it is suggested to turn off the card 1 card 2 notification, but there is no bell in Do Not Disturb. But it's better than no notice on the bulletin board or two notices.
