The various implementations described herein include systems, methods and/or devices used to enable touchscreen proximity sensing. An exemplary method is performed at a touch sensitive device and includes detecting the presence of water on a capacitive sense array (CSA). The method detects decreased electrode responses from at least a subset of a plurality of sensor electrodes of the CSA that satisfy one or more first trigger conditions. The method further includes: (1) normalizing the CSA based on the detected decrease in electrode responses to form a second baseline, (2) determining that the water is removed from the portion of the CSA based on one or more subsequent electrode responses from at least the subset of the plurality of sensor electrodes that satisfy one or more second trigger conditions, and (3) normalizing the CSA based on the detected one or more subsequent electrode responses to form a third baseline.

Water detection and wipe detection algorithms for touchscreen proximity sensing

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.
