How does Huawei intercept short messages and delete them automatically?

Huawei mobile phones can intercept short messages, but they can't automatically delete intercepted short messages (and almost all mobile phones can't automatically delete intercepted short messages). However, after interception, the mobile phone setting interception and setting interception without notification have no notification effect. The following demonstration:

Demonstration equipment: Huawei enjoys 20, EMUI9. 1, Huawei mobile phone housekeeper 9. 1.

First, open Huawei's mobile phone housekeeper and enter the harassment interception function.

Second, find the blacklist and click Open.

Third, click Add below, and then choose an add method. The following is a demonstration of manual addition.

4. Enter the number and click OK to add the number to the blacklist. After adding, calls and text messages at this number will be blocked.

5. Then return to the interception rules interface, click the interception notice, and the pop-up option is to click the blacklist without notice.
