Why does the Xiaomi 14T display the wrong aperture value when shooting in portrait mode?

The aperture of the front camera of the Xiaomi 14T is f/2.0, while the aperture of the rear camera is f/1.77. Several factors will affect shooting in portrait mode, which makes the phone display the wrong aperture. The reason for this issue could be the misunderstanding of the adjustable F value in the portrait mode.
If the phone displays the wrong aperture value when shooting in portrait mode, please refer to the following details:
1. The F value adjusted in the portrait mode represents the degree of blurriness. It is not the same as the F aperture in the image properties;
2. If you want to adjust the aperture, you can only do so by changing the zoom value.
If the above methods cannot solve the problem, please apply for the after-sales inspection.
