Whenever the orientation of UI is changed, all applications rotate 90 or 270 degrees (not only the foreground application). By default, the UI does not rotate automatically to any other orientation while opening or closing an application, swapping to another application, or in the case of embedded applications or seamless task flows. In addition, the UI should not change its orientation when another view within an application is opened.
Applications that support only one orientation, and thus trigger automatic orientation switch, do not change the orientation of other applications. That is, if the orientation is ’portrait’ before launching a ’landscape-only application’, it is portrait even after exiting it.
An exception to this rule is for the applications that are launched from the landscape application itself (for example, the Go to gallery option in the Camera application) or embedded within the application (for example, the embedded Browser within an image editor when downloading content). In these cases, one orientation should remain throughout the task flow, and the original orientation should be returned only after exiting the application that triggered the rotation.
No queries or notes are recommended to inform or ask the user about rotation.
