I prefer simple wallpaper, then mainly black wallpaper, and occasionally some landscape wallpaper, because black wallpaper has many advantages, such as many designs on the market now, such as Liu Haiping, water drop screen and hole digging screen, which can be perfectly hidden, and then icons and words are more readable on a black background. In addition, on some screens made of materials, black wallpaper also has the effect of saving electricity, so I usually use black wallpaper the most. Of course, I will use some other types, such as colorful wallpaper. Some, but few.
