Abstract: An unlocking method and an electronic device relate to the field of terminal technologies. The method includes: when an inner screen (141) is in a locked and closed state, and an outer screen (142) is in a locked and black state, detecting an operation of turning on the outer screen (142), turning on the outer screen (142), starting a rear-facing camera (132), and starting a first timer; if a face image captured by the rear-facing camera (132) before the first timer expires matches a preset face image, unlocking the outer screen (142), entering a master mode, closing the rear-facing camera (132), stopping the first timer, prompting a user to perform face authentication, and starting a second timer; detecting an operation of unfolding the inner screen (141), turning on the inner screen (141), starting a front-facing camera (131), and locking the outer screen (142); before the second timer expires, if the front-facing camera (131) captures a face image, closing the front-facing camera (131), and stopping the second timer; and if the face image captured by the front-facing camera (131) does not match the preset face image, unlocking the inner screen (141), and entering a guest mode. Therefore, the present invention helps improve convenience of entering the guest mode.

Abstract: This disclosure provides a method for displaying application icons. The method may be applied to an electronic device having an expansible screen. When the expansible screen is in a first state, a first group of application icons are displayed in a shortcut window region of the screen, and if the expansible screen changes from the first state to a second state, a second group of application icons are displayed in the shortcut window region of the screen. A quantity of the second group of application icons is greater than a quantity of the first group of application icons. The first state indicates a state in which the expansible screen is not expanded. The second state indicates a state in which the expansible screen is expanded. Corresponding electronic device and storage media are also described.
