Samsung has always had its own take on the Android UI. After TouchWiz and Samsung Experience, the company first introduced One UI, based on Android 9 Pie, in 2018 to facilitate one-handed operations on its larger devices. It also brought some cool features like a dark system mode and more, and Samsung kept adding more features over the years. The latest version, One UI 5.0, based on Android 13, is currently in beta.

All Android phones have a launcher, and Samsung’s launcher, which is part of its One UI overlay, is called One UI Home. The launcher allows you to customize various aspects of the phone’s home screen. You can add widgets, change the appearance of app notifications, and adjust the appearance of the app drawer, to name a few.
