After setting the wallpaper, the wallpaper deformed and enlarged

Because the aspect ratio of the picture does not match the proportion of the phone screen, the phenomenon of stretching and enlargement will appear after setting the wallpaper. For example, when the screen ratio of the phone is 20:9 and the photo ratio is 4:3, the picture will be cropped in order to fill the screen. It is recommended that you crop the photo to an appropriate ratio in the album before setting the wallpaper.
