The ability to change the orientation of the main interface of Android devices, so that it displays in either portrait or landscape mode, is a feature controlled by device settings. The behavior allows users to view the home screen and its associated widgets and icons in a manner best suited to their current needs. For example, when viewing images or videos, many individuals prefer a wider, landscape view on the main interface.
This functionality enhances user experience by providing flexibility and adapting to various content consumption scenarios. Its evolution reflects the increasing importance of multimedia use on mobile devices and the need for optimized viewing experiences. Historically, operating systems were designed with a fixed orientation, but the demand for adaptability led to the inclusion of orientation control features.
