Unlocking method and electronic device

Abstract

An unlocking method and an electronic device relate to the field of terminal technologies. The method includes: when an inner screen () is in a locked and closed state, and an outer screen () is in a locked and black state, detecting an operation of turning on the outer screen (), turning on the outer screen (), starting a rear-facing camera (), and starting a first timer; if a face image captured by the rear-facing camera () before the first timer expires matches a preset face image, unlocking the outer screen (), entering a master mode, closing the rear-facing camera (), stopping the first timer, prompting a user to perform face authentication, and starting a second timer; detecting an operation of unfolding the inner screen (), turning on the inner screen (), starting a front-facing camera (), and locking the outer screen (); before the second timer expires, if the front-facing camera () captures a face image, closing the front-facing camera (), and stopping the second timer; and if the face image captured by the front-facing camera () does not match the preset face image, unlocking the inner screen (), and entering a guest mode. Therefore, the present invention helps improve convenience of entering the guest mode.
