SystemUI Tuner

SystemUI Tuner is an app that lets you customize aspects of your Android device that the default configuration options normally don't allow you to customize. And best of all, the app doesn't require root privileges in order to work.

With this handy app, you can choose what icons you want to appear on your status bar, set the importance of notifications, customize the speed of some animations and transitions, and even hide the status or browsing bar directly. It is important to note, however, that SystemUI Tuner does not work with all devices on the market. For example, some of the features don't work correctly on MIUI or Samsung devices.

SystemUI Tuner is an excellent customization app, that lets you give your device a unique and personalized look. You can even enable some 'hidden' Android features that are disabled by default.
