Abstract:
A method and an apparatus for determining existence of a foreign material on a surface of a fingerprint sensor, and a terminal are provided. The method includes the following. A current capacitance value of the fingerprint sensor of the terminal is obtained. A first difference between the current capacitance value and a preset capacitance reference value is calculated. Determine that the foreign material is present on the surface of the fingerprint sensor when the first difference is within a preset foreign-material threshold range.

Claim (Index 14):
The apparatus of  claim 8 , wherein the processor is further configured to:\n set the preset foreign-material threshold range according to experimental data of capacitance change tests performed on the fingerprint sensor when different conductive foreign materials are present on the surface of the fingerprint sensor.
