Why doesn't Xiaomi mobile phone have face recognition application?

I used Xiaomi 6X. Personally, I think this function has low security. I wore nothing when I entered my face, and I was drunk when I put on sunglasses. I wonder if other models of mobile phones have such problems.

With the development of science and technology, face recognition on mobile phones is nothing new. Many models of Xiaomi can support face recognition. But what if Xiaomi's mobile phone face recognition fails?

Xiaomi mobile phone face recognition fault

1. Please keep the front camera clean and unobstructed, and then try to unlock the face.

2. When the face is unlocked, the mobile phone is facing the face, and at the same time, the situation that clothes, hair, sunglasses, masks and heavy makeup affect facial recognition is reduced.

3. Try not to unlock in dark light, strong light, backlight, smoke and other environments.

4. Delete the face data and re-enter the face, or restart the phone and try again.
