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 8):
An apparatus for determining existence of a foreign material on a surface of a fingerprint sensor, comprising:\n a processor; and a memory, coupled with the processor and configured to store program codes which when executed by the processor become operational with the processor configured to:\n obtain a current capacitance value of the fingerprint sensor of a terminal; \n calculate a first difference between the current capacitance value and a preset capacitance reference value; and \n 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.
