3D Wallpaper Clock Widget HD is for personalizing a phone’s appearance with moving backgrounds and related designs. Its live wallpapers are described as 4K and can be applied to the home screen, the lock screen, or both. Animated keyboard backgrounds and call screen graphics provide additional ways to change the device’s look.
Choosing a background for the home or lock screen
When the goal is to replace a static screen background, the app offers a selection of 3D live wallpapers. Choose a design and apply it to the home screen and lock screen in a few taps; the description also says you can use a wallpaper on either screen. The stated 4K quality is intended to provide a crisp display, though no device-specific resolution details are given.
Matching the keyboard to a wallpaper
For a more coordinated appearance while typing, the app includes animated custom keyboard backgrounds. You can select from the available designs to find one that matches your chosen wallpaper. The source describes these backgrounds as animated, but does not specify additional keyboard tools or settings.
Changing the call screen design
The app also provides graphics for call screens, extending its visual customization beyond wallpapers and the keyboard. These designs can add another coordinated visual element to the phone. The description does not provide details about selecting, setting, or customizing individual call screen designs.
