A device may include a capacitive touch screen having a surface and a sensor grid underneath the surface having a set of conductive columns and a set of conductive rows. The device may measure a mutual capacitance between a subset of conductive columns or a subset of conductive rows associated with a sensor grid, and compare the measured mutual capacitance between the subset of conductive columns or the subset of conductive rows to a baseline mutual capacitance associated with the set of conductive columns and the set of conductive rows. According to the comparison, the device may determine a presence of a protective layer in contact with the surface of the capacitive touch screen, and adjust an operating characteristic of the sensor grid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of a protective cover film on a capacitive touch screen","description":"Methods, systems, and devices for detection of a protective cover film on a capacitive touch screen are described.
