What is the principle of Meitu Xiu Xiu's beauty camera? Is there any bad influence on the camera or hardware equipment of the mobile phone?

The principle of beauty camera is to do software post-processing on photos in mobile phone after taking photos, which is the same as ps on computer after taking photos, and it is impossible to have any impact on hardware.

Different camera software controls the camera to take photos by calling the system software interface, but the compression ratio of photos saved by different software may be different, and the post-processing of images will also lead to the decline of image quality.

After downloading the beauty camera, the picture quality becomes worse (the statement of pixel deterioration is very inaccurate), which may be related to the software saving and processing photos, as long as the original camera software takes pictures unchanged.

If the original camera software is also getting worse, it is probably your psychological illusion.
