O3 Icon Pack is composed of over 4100 icons inspired by the style of the Oxygen operating system, with soft shapes and colors typical of MIUI design. This application needs a compatible launcher to work. Read the list of supported launchers below and instructions on how to apply the icons or change them manually. In the icon package you can find many alternative icons to associate manually with your favorite app. The application of custom alternative icons depends on the Launcher you have been using: on Nova Launcher / Evie Launcher / One Plus Launcher you have to long press on the icon you want to change, then click on "Edit" or its symbol, or directly on the icon thumbnail, then select the O3 icon package and you're done!
