The mobile phone and card are lost, and Beijing Health Bao can't display the previous number displayed by the avatar.

1. When Beijing Health Bao can't display the head portrait or face recognition fails, it may be caused by weak signal, poor network or insufficient light.

You can try to switch the light source at this time. Light may affect the face recognition effect. It is suggested to change the angle or position and choose a place with moderate light distribution to try again. For some customers whose mobile phone memory space is relatively small, they should turn off their mobile phones or delete some useless software accordingly.
