Device and method for adjusting orientation of a data representation displayed on a display

An electronic device, preferably in the form of a mobile phone, comprising a support structure and a camera carried by the support structure. An orientation detector is connected to the camera. The orientation detector is configured to identify images features in an image captured by the camera, such as the eyes and the mouth of the user, and to determine rotation orientation of the image relative to a reference orientation. A display carried by the support structure is configured to display a data representation, and further to display this data representation in an orientation dependent on the determined rotation orientation. This way a data presentation can e.g. be displayed in a portrait orientation or in a landscape orientation in dependence of which rotational orientation the device is currently held in when the data representation is viewed by a user of the electronic device.
