What should I do if QQ unfreezes face recognition and keeps displaying error code 653?

Because of the software version, facial recognition keeps displaying error code 653. Please try to update to the latest version.

There are several reasons for the failure of face recognition: network conditions, lighting conditions and software version.

Network status: the device is not connected to the network, or the signal is too poor to upload the input data to the terminal and execute the next instruction.

Lighting conditions: In face recognition, the environment is dark, and the equipment cannot clearly distinguish faces.

Software version: the system pushes the latest software version, but the equipment is not updated, which affects the data transmission to the terminal.

Problem-solving skills for face recognition;

Face recognition failure may have little to do with face value. Chances are, you just haven't mastered the skill of brushing your face yet!

Allow to turn on the phone camera:

Many users will ask questions such as "why can't the camera shoot" and "why can't I upload photos of my ID card". In fact, the main reason is that when users open the app software, they refuse the software access to the camera function. Just re-open the relevant permissions in the system settings.

Take clear pictures:

Be sure to take good photos and adjust the light to avoid too strong or too dark light; At the same time, we should also pay attention to the shooting angle, avoid the reflected light spots, and try to keep the horizontal front shooting. Remember, hands can't shake, photos can't "paste"!

To completely "expose" your true self:

In order to verify the identity information, face recognition technology collects dynamic video streams for recognition. So please blink, turn your head and open your mouth according to the screen and voice prompts. It should be noted that a large area of bangs, hats or glasses may lead to recognition failure.

It is worth mentioning that some people use photos or videos instead of "brushing their faces" in an attempt to get away with it, but they don't know that the face recognition system will conduct live detection.

In the face of face recognition technology, the trick of using photos or videos is to show the prototype. Therefore, when carrying out face recognition, fully exposing one's complete face is the best guarantee to pass the recognition.

Update the photo information to the public security network:

When all the above three points are achieved, but still can't be recognized by the machine, it is necessary to consider whether your photo information on the public security network is invalid. If the photo information is really out of date, you can go to the police station or the accreditation center to update (reissue) the ID photo.
