Here is another powerful, fast, and highly customizable home replacement for Android 4.0 Ice Cream Sandwich free to download ~ Apex Launcher. It is a nice ICS Launcher to replace default Samsung TW Launcher in Android 4.0.3 ICS Samsung Galaxy S II for you and me. Just like Nova Launcher, root access is needed only when you want to add widgets from the drawer. Apex Launcher needs to be installed as a system app which requires root access. All other Apex Launcher features are fully functional without root access.
