Description
The Device Posture API is an API which helps targeting foldable devices. It provides developers the ability to query the posture of the device (through MQs or JavaScript) and provide a differentiated experience to the user. It does not expose the hinge angle sensor value but a set of "posture" which describe the current physical position of the device.
As this time this API applies only to Android and Windows OSes. Android provides the necessary OS APIs over here. Windows doesn't have an official API yet but instead relies on OEMs implementing the following specification in their middleware pre-installed software.
This API is to complimentary of the Viewport Segments which also helps targeting foldable devices (WebKit position requested over here).
This API is enabled by default on Samsung Internet.
