In one aspect, the present disclosure relates to a method including detecting force applied to a force sensing layer in a device and detecting touch contacts applied to a touch screen layer in a device. The method also includes determining if the location and/or amount of force detected by the force sensing layer correlates to a touch contact, and, if it correlates, treating the force as front-side force, while if the location and/or amount of force detected by the force sensing layer does not correlate to a touch contact, treating the force as a back-side force. Based on the type of force detected, appropriate action may be taken, including back-side specific actions such as multi-tasking application switches or content or viewport manipulation.
