The functionality that adjusts a display’s orientation based on the device’s physical position is a standard feature in many mobile operating systems. As a device is tilted or rotated, the screen content adapts to maintain a readable and user-friendly view, shifting between portrait and landscape modes. For example, when a user turns a smartphone on its side while watching a video, the screen image usually expands to fill the width of the display.
This feature offers increased convenience and accessibility, allowing users to view content in the manner most suitable to their needs and the specific application. It enhances the viewing experience for videos, photos, documents, and web pages. Early mobile devices lacked this capability, requiring manual adjustment of the screen orientation which proved cumbersome and less intuitive for the user.
