The phrase refers to Android-based mobile devices equipped with a lens offering an ultrawide field of view, typically represented as 0.5x zoom in the camera application. This lens captures a significantly wider perspective compared to the standard main camera, allowing more of the surrounding scene to be included in a single photograph or video. For instance, capturing a panoramic landscape or a large group of people in a confined space is made easier with this capability.
The inclusion of such lenses on Android phones has become increasingly common due to the demand for versatile photography options. These ultrawide lenses provide users with the ability to create visually compelling images and videos that would be difficult or impossible to achieve with a standard lens. This feature is especially beneficial in architectural photography, landscape photography, and situations where capturing a broad view is essential. The historical development of mobile phone cameras reflects a trend towards offering a wider range of focal lengths and perspectives to users.
