1. A method, comprising:

  • at an electronic device with one or more processors, memory, and a touch-sensitive display;

    receiving 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;

    receiving a touch input on the touch-sensitive display;

    determining 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, processing the touch input as an intentional touch input;

    upon determining that the device is in the second proximity state, processing the touch input as an unintentional touch input; and

    in response to a change in the received proximity data, changing the processing of the touch input.
