Abstract
A method in an electronic device having one or more processors operable a fingerprint sensor and one or more other sensors includes detecting, with a fingerprint sensor, false fingerprint data. After detecting the false fingerprint data, the method determines whether the electronic device is disposed within a pocket. Where the electronic device is disposed within the pocket, the method transitions the fingerprint sensor from an active mode to a low power or sleep mode.
