Claim:
1. A handheld electronic apparatus, comprising: a display, comprising a touch panel; a proximity sensor; a communication unit, being configured to establish a call; a processing unit, being electrically connected to the display, the proximity sensor, and the communication unit and configured to disable the touch panel during the call based on a detection of presence of nearby object of the proximity sensor; and a motion sensor, being electrically connected to the processing unit and configured to detect an instant acceleration value of the handheld electronic apparatus, wherein the instant acceleration value comprises an X-direction value, a Y-direction value, and a Z-direction value; wherein the processing unit determines a value that is only related to the instant acceleration value relates to at least one of the X-direction value, the Y-direction value, and the Z-direction value based on at least a first difference between two of the X-direction value, the Y-direction value, and the Z-direction value and determines whether the value is greater than an acceleration threshold while the touch panel is disabled during the call and the processing unit enables the touch panel during the call based on a determination that the value is greater than the acceleration threshold.
