The on-screen control element present in Android 6.1, typically located at the bottom of the display, provides access to core system functions. These functions commonly include Back, Home, and Recent Apps. Its primary purpose is to facilitate user interaction and system navigation. As an example, tapping the triangle icon redirects the user to the previously viewed screen.
This feature offered a consistent and readily available method for traversing the operating system. Its benefits included increased user familiarity and simplified mobile device control. It represented a shift from physical buttons present on earlier Android devices and allowed for greater flexibility in device design and screen utilization. It was a key element in shaping the overall Android user experience during that era.
