Why is Huawei's mobile phone photography the opposite? How to adjust it?

Photos or videos taken with the front camera are upside down.

The cause of the problem:

When the "selfie mirror" is turned on, the picture taken is opposite to the real scene and consistent with the photo preview;

When the selfie mirror is turned off, the picture taken is the same as the real scene, contrary to the photo preview.

Solution:

When the phone is in the front camera mode, slide the screen to the left or click the setting icon in the upper right corner to enter the "Settings" interface, and turn on or off the "selfie mirror" switch as needed.
