Abstract
The invention is directed to systems, methods and computer program products for switching between a dry mode and a wet mode for a mobile device. An exemplary method comprises: determining a first capacitance on a mobile device touchscreen using a sensor associated with the touchscreen, wherein the first capacitance is determined when the touchscreen is submerged under a body of water; comparing the first capacitance to a threshold capacitance; determining whether the first capacitance is greater than or equal to the threshold capacitance; and in response to determining the first capacitance is greater than or equal to the threshold capacitance, switching the touchscreen from a dry mode to a wet mode, wherein in the wet mode, a location associated with a user's touch is determined based on a capacitance at a point on the touchscreen associated with the user's touch being less than the first capacitance.
