Abstract
The invention relates to an electronic mobile device (10; 20) comprising a device mode control unit (5) arranged to switch the mobile device from a first operational mode into a second operational mode. An orientation sensor (18; 28) is configured to measure a current orientation of the mobile device. A processor (6) periodically receives the current orientation from the orientation sensor, periodically stores the received current orientation as a reference orientation, and periodically calculates a differential angle between the current orientation and the stored reference orientation. The device is switched from the first operational mode to the second operational mode if the differential angle is above a predefined angular threshold value. A frequency of said periodically receiving and periodically storing the current orientation as the reference orientation is lower than a frequency of said periodically receiving the current orientation, periodically calculating and periodically comparing the differential angle.
