SystemUI Tuner is special software that has been designed to help users customise their experience when using various different apps that have been created for the Android platform. This can be done in various ways such as customising the app tool bar and notifications. However, it should be noted that SystemUI Tuner has been primarily designed for users of Samsung devices and people who are using other brands of Smartphones and tablets may find that the software does not run as smoothly as could be hoped for.
