Electronic device with touch-sensitive display and gesture-detection

A method comprising:

• utilizing transmitters and receivers of an electronic device to detect at least one object spaced from the electronic device;
• when the transmitters are transmitting, determining first signal values utilizing touch sensors of the touch-sensitive display to obtain first baseline noise values when no touch is detected by the touch sensors;
• when the transmitters are transmitting, detecting a touch while determining second signal values utilizing the touch sensors, and applying the first baseline noise values to the second signal values to reduce the effect of noise created by the transmitters on the second signal values when identifying a touch location;
• when no touch is detected based on the second signal values and the transmitters are not transmitting, utilizing the second signal values to obtain second baseline noise values;
• when the transmitters are not transmitting, detecting a touch while determining third signal values utilizing the touch sensors, and applying the second baseline noise values to the third signal values to reduce the effect of noise created by at least one source other than the transmitters on the third signal values when identifying a touch location.
