The phrase denotes an application package file specifically for the Android operating system, referring to the second version of a particular application commonly used for device customization. This package is often sought to modify the appearance and functionality of an Android device’s home screen and app drawer, providing an alternative to the device’s default user interface.
The availability of such files allows users to personalize their mobile experience, often resulting in improved performance and added features compared to the stock launcher. Historically, these customizable interfaces gained traction as users sought to overcome limitations imposed by device manufacturers, leading to a thriving ecosystem of alternative launchers and related files.
