Abstract
The various implementations described herein include systems, methods and/or devices used to enable touch screen proximity sensing with suppression of false ear touches. An example method is performed at a touch sensitive device and includes enabling or disabling grip suppression to prevent false touches from a user's ear during a phone call based on signals from motion sensors, such as gyroscopes and/or accelerometers, that indicate a direction of the touch sensitive device with respect to a user's face. Another method is performed at a touch sensitive device and includes allowing a user to input on the touch screen a predefined gesture to enable normal touch operation of a touch screen of a touch sensitive device when the device is in a proximity sensing mode.
