Abstract
A portable communication device having a touch-sensitive input device is configured to selectively suppress spurious key press events based on the orientation of the portable communication device. The device is equipped with an orientation sensor and processing circuitry to suppress key press events when the device is oriented in a predefined orientation, such as a predefined orientation representative of an active call.
