I downloaded Mobile9 Deco icons. It doesn't tell you how to use them. Or where they went on my phone. I have a Galaxy S5. Does anyone know anything about this app?
The icons require one of the following launchers to be installed in order to apply them. These icons are packed into APK files and launchers use them accordingly. Install any of the following launchers through Google Play and you should have the possibility to apply them to your phone:
Go Launcher, Nova Launcher, Themer Launcher, MIUI Launcher, ADW Launcher, Buzz Launcher.
