What is One UI? How does it support one-handed use?

One UI is Samsung's custom user interface for Android devices, and replaces the previous user interface known as Samsung Experience. One UI is designed to keep everything within reach for one-handed users, and improves the experience of using larger phones by reducing the need to readjust your grip. The benefits of One UI are most noticeable within apps such as Messages. Access to both your Conversations and Contacts is located at the bottom of your screen, as are the keypad, the "Attachments" icon, and the "Send" icon when you are responding to a message. This design allows you to access what you need when you need it, so you can respond quickly and move on to the next task. For more information about One UI, please visit www.samsung.com.
