An electronic device having a foldable screen, where when the foldable screen is in a folded state, the foldable screen is divided into a primary screen and a secondary screen. When a first component disposed on the primary screen is in a working state, or an application that invokes the first component is in the working state, when a screen switching event is detected, the electronic device is prohibited from switching to a state in which only the secondary screen performs display, to avoid a case in which a user is close to the primary screen but the primary screen does not perform display.
