Interception principle of abnormal high frequency interference number

The reason is that the "interception threshold" is too high, and mobile phone butlers of major brands will set interception thresholds. When the setting is too high, those harassing calls that are not marked frequently can still be answered normally. At this time, it can be solved by lowering the interception threshold, and the lowering process is as follows:

Materials required: Huawei EMUI9. 1 system demonstration (the setting method of other versions of EMUI system may be different, and the setting method of other brands of mobile phones is similar).

1. Open Huawei Mobile Manager and click "Harassment Interception".

2. Click "Interception Rules" at the bottom of the interception interface.

3. Click "Telephone Interception Rules" in the interception rules (if you need to set SMS interception rules, click SMS interception rules, and the operation process of lowering the threshold is the same).

4. In this interface, click "Interception Threshold" below.

5. Click the first item in the interface, "Harassing phone calls".

6. At this time, the harassing phone interception threshold bar will pop up. Just lower the threshold here and click "Save" (Note: it cannot be set too small, because some numbers that have been maliciously marked several times will also be intercepted).
