Xiaomi mix4 front camera is very dark at night.

The front camera of Xiaomi mix4 is dark at night, because the front camera does not have night vision function. If it is too dark, a black screen will be displayed.

1. Check whether the camera is blocked.

2. If you use a third-party camera software, I suggest you take photos with your own camera function to see if there is a black screen.

3. If the camera doesn't work, please turn off the phone and restart it.
