6. A non-transitory computer readable storage medium storing executable program instructions, which, when executed by an electronic with one or more processors, memory and a touch-sensitive display, cause the electronic device to: receive proximity data from a proximity sensor of the electronic device, wherein: the proximity sensor is configured to obtain proximity data corresponding to a location of a user relative to the electronic device; and the proximity data represents at least one of a distance and a rate of change of distance; receive a touch input on the touch-sensitive display; determine whether the device is in one of a first or second proximity state based on the received proximity data, wherein the second proximity state occurs when the electronic device is proximate to the user's ear; upon determining that the device is in the first proximity state, process the touch input as an intentional touch input; upon determining that the device is in the second proximity state, process the touch input as an unintentional touch input; and in response to a change in the received proximity data, change the processing of the touch input.

The non-transitory computer readable storage medium of claim 6 , wherein the executable program instructions cause the electronic device to: upon determining that the device is in the first proximity state, display information on the touch-sensitive display in a first display state, wherein the first display state is a regular power mode; upon determining that the device is in the second proximity state, cease to display information on the touch-sensitive display in a second display state different from the first display state, wherein the second display state is a low-power mode.
