If you're a power user, or simply want to make your Android phone a little more personal, you'll want to install System UI Tuner. This app is a hidden utility that lets you change your phone's UI. You can do things like hide the navigation bar, show only the status bar, or change the font and color of your phone's main menu. You can even hide all the apps from the main menu!

There is a way to make this app work with your Android phone, but it is not compatible with Samsung devices.
