How do mobile phones intercept spam messages?

Taking Huawei P20Pro as an example, the specific operation steps are as follows:

1. Open Info APP through the mobile phone desktop.

2. In the information window, click the function button in the upper right corner and select "Harassment Interception".

3. In the "harassment interception" window, click "SMS interception rules".

4. In the "SMS Interception Rules" window, click to open the "Intelligent Interception of Spam Messages" function and finish the operation.

5. If a strange number that is not marketing continues to harass the owner with short messages, the function of "blocking strange short messages" can be turned on at the same time.

Matters needing attention

1. The "Intelligent Blocking Spam Messages" function of mobile phone needs to download the Spam Number Identification Library to complete intelligent blocking. Therefore, it is necessary to provide the "mobile phone housekeeper" App with networking permission in order to update the identity database data in time.

2. If you still can't intercept some harassing short messages according to the above operation method, you can set a keyword blacklist through the harassment interception-interception rule to intercept stranger short messages containing keywords.
