When you unfriend someone, you don’t get any reminders until you send them a message.

When an exclamation mark appears in a chat box, I believe many people will feel very uncomfortable.



In addition to sending messages, friends can only check who has deleted their friends by setting up a group or transferring money, which is quite troublesome and may lead to some embarrassing situations.

In order to quickly check the relationship without disturbing the other person, a third-party wechat “powder” tool was once very popular.



However, many illegal groups and criminals often make plug-in apps under the guise of “clean powder”.

These apps appear to be so-called “clean powder” programs, but may actually steal all kinds of information from users’ phones.

Since the third party “clean powder software” can not be used blindly, so, only wait for wechat official launch of “clean powder” function.



On April 23, Tencent Technology (Shenzhen) Co LTD released a patent for “one-way friend detection method, device, media and computer equipment for social accounts,” according to the Tianyancha APP.

The patent reads:

Obtain the one-way friend detection command triggered by the social application interface, and the one-way friend detection command includes the account id of the detected social account;

Based on the one-way friend detection instruction, and obtain the one-way friend identification determined according to the first address book of the detected social account and the second address book corresponding to each social account in the first address book;

Obtain one-way friend information according to the one-way friend identification; The one-way friend information is displayed in the social application interface.



Basically, it checks if you’ve been unfriended.

We can also see the specific operation mode from the attached picture of patent literature instruction: click on the upper right corner of wechat address book page, and you can see the option of “clearing individual friends”.



Then the address book list of your friends will be displayed, that is, your wechat friends have been deleted. You can click the delete button in the upper right corner to delete them.



Tencent said the method is simple to operate and does not need to send a lot of redundant information, improving the efficiency of one-way friend detection and reducing system consumption.

However, after the patent was published, it caused a lot of ridicule on the Internet.

Some netizens believe that QQ has had this function for a long time, and wechat’s patent was also applied on October 22, 2019, so it has not been made public until now.



Some netizens believe that wechat can not directly delete, because chat records involve a lot of evidence, one party is not qualified to delete the other party.



Although this feature is still in the patent stage, it is not officially available, but it should be soon.

As a national super APP, I hope wechat can listen to users’ opinions and improve its functions.

Last but not least, it is not recommended to use all the third-party friend relationship detection tools currently on the market, as privacy leakage and fraud may occur.
