The question of what is System UI on an Android often arises when users encounter terms like the status bar, navigation bar, or lock screen.
System UI, short for System User Interface, refers to all the visual elements on your Android device that are not part of any specific app.
It is an integral layer of the operating system, enabling users to interact seamlessly with their devices. Here’s everything you need to know about System UI.
