The next step is to launch the application. When the application starts loading, you need to click on the 'Home Screen' icon to launch the application. You will get various options like a wallpaper for the application, as well as various color schemes and images to use as wallpapers for the application. The last step is to launch the application, using the Home key. You can see an avatar of your Redmi Note 7 complete with a smiley face, at the end of the avatar.
