One UI is a user interface developed by Samsung Electronics for its Android-based smartphones, tablets, smartwatches, and other devices. It was introduced as a replacement for Samsung’s previous user interface called Samsung Experience (formerly known as TouchWiz) and debuted with the release of the Samsung Galaxy S9 and S9+ smartphones in 2018. One UI is designed to provide a more intuitive, streamlined, and visually appealing user experience for Samsung device users. Here are some key features and characteristics of One UI:
