Hello, if this situation is not blacked out, you should consult the operator. If you are often troubled by harassing calls, you can try to install Tencent mobile phone housekeeper to intercept defensive harassing calls. In addition to intercepting and marking harassing calls, housekeepers can also intercept spam messages and blacklist annoying numbers. The operation method is as follows.

1. Install Tencent mobile phone manager and turn it on. The manager will automatically intercept "ringing phone" and "common scam messages" and prompt you to mark them.

2. After interception, you can only view the intercepted phone records through the "Harassment Interception" function in "Security Protection".

3. The housekeeper also provides the function of modifying the "mislabeled" phone. At the "Digital Mark", click "I want to correct my mistakes" to make changes. At the same time, you can see the latest marked numbers here, as shown in the following figure:

Click "Mark the latest strange number" to mark the recent incoming calls directly.

4. In addition, click on the "spam message" column to view the recently intercepted spam messages. Click SMS Delete, report and add more (restore to mobile inbox/add to whitelist/blacklist), as shown in the following figure:

5. In the "Settings-Blacklist" in the upper right corner, you can also directly mark harassing calls as blacklists. Butler provides four ways to add blacklist, which is convenient for users to intercept quickly and accurately. As shown in the figure below:

6. At the same time, the housekeeper also provides more personalized function options in the settings, which you can set one by one according to your daily needs:
