Abstract
A method, a mobile device, and a computer program product enable capacitive proximity sensing in a mobile device. The method includes determining, by a controller of a mobile device, whether the mobile device is participating in an active phone call. In response to determining that the mobile device is participating in an active phone call, the method further includes determining if an ear speaker mode of the mobile device is enabled. In response to determining that the ear speaker mode of the mobile device is enabled, the method further includes activating a driven shield to at least partially shield a capacitance sensor from sensing object capacitance at a second side of the mobile device that is opposed to a first side with the ear speaker.
