Abstract: Multi-screen unlocking methods and electronic devices are disclosed. In an implementation, a method includes: in response to detecting a first operation on an electronic device, a first display displays a first screen lock interface, and a second display displays a second screen lock interface, where the first screen lock interface is different from the second screen lock interface. The second display displays a second unlocked interface in response to detecting a second operation on the second display. A second application indicates the electronic device to switch from a screen-locked state to an unlocked state, and sends a first message to a first application. In response to the first message, the first application displays a first unlocked interface by using the first display. The first display is locked by using the first application, and the second display is locked by using the second application.
