Apple offers a variety of dynamic wallpapers for iPhones and iPads that let you add an element of depth and movement to the background. To set a dynamic wallpaper on your smartphone or tablet:
First, open the Settings app on your iPhone or iPad. If you can not find it, drag it down the Home screen of your device to use Spotlight Search.
Scroll down the Settings menu and tap Background Image.
Select the option "Choose a new wallpaper." different types of built-in wallpapers. Select "Dynamic" at the top of the menu.
You can select one of seven dynamic wallpapers. While six contain monochrome balls, the first option consists of a mixture of the different variants. Select the wallpaper whose preview you want to preview.
If you want the dynamic wallpaper to appear in full-screen mode, tap Set. You can select "Cancel" if you want to see one of the other options.
Now select "Both" to set the dynamic wallpaper on the lock screen and the home screen, or choose from the following options to display it in a single place.
Done! You should be redirected to your homescreen, where you can see the dynamic wallpaper in action (if you set it to either or only on homescreen).
Unfortunately, Apple did not open dynamic backgrounds for third-party developers. In the meantime, download or create your own live wallpaper if you want more options to choose from.
