The Android operating system offers users several options for customizing the home screen experience. One such option is a launcher, which dictates the visual layout and functionality of the home screen, app drawer, and related elements. Some device manufacturers pre-install a specific launcher, which often becomes the default user interface.
The implementation can offer a cleaner, streamlined home screen interface, often emphasizing simplicity and ease of navigation. Its advantages may include reduced resource consumption, contributing to improved device performance and battery life. Historically, Google has utilized this streamlined user interface in its own devices, aiming to showcase the core Android experience.
