System UI provides the User Interface for an Android system. It basically determines how your system interface and navigation look without customization from an application. You might see it asSystem UIorcom.android.system.ui.
System UI Tuner is the functionality that allows users to customize their system’s user interface. A hidden System UI Tuner setting was introduced in Android 6 Marshmallow, which stayed till Android 7 Nougat.
