To use your own icon for any Lite App, open the Lite App, then tap “Customize”.
Under “Theme”, find the current icon, and tap on it to change.
Pick an icon and set it as your new icon!
Some photo picker apps (i.e. the external app that is used above to select an icon) do not support transparency. We recommend using Google Photos or a file picker app (instead of a photo picker app) to choose the icon so that it will retain transparent areas of the icon correctly.
