A launcher app defines what your home screen looks like and how you organize and interact with all of your apps. The launcher that came with your phone puts the Google search widget and a clock widget on the home screen. See what that home screen looks like and how you can customize it.
If you want to totally change the look and feel of your home screen, you’ll need to download a new launcher and update settings to use that launcher. Launchers frequently include new sets of wallpapers, new gestures for interacting with your phone, and customizable elements for your home screen.
You can switch back to the original launcher and its home screen at any time.
Touch Default apps > Home app.
Or, touch Advanced > Default apps > Home app.
Select the launcher you want to use.
You can only delete launchers that you installed.
Touch & hold the launcher's app icon, then touch
> Uninstall.
