Abstract: This application provides a method for determining a foldable screen included angle and associated devices of the method, and relates to the field of terminal technologies. The method includes: for each display screen, acquiring, by an acceleration sensor, an initial acceleration signal at time t, and acquiring, by a gyroscope sensor, an initial angular velocity signal at time t; for each display screen, performing first preprocessing on the initial acceleration signal at time t to determine a target value of a gravitational acceleration signal at time t, and performing second preprocessing on the initial angular velocity signal at time t to determine an intermediate angular velocity signal at time t; detecting a state of the foldable screen according to the gravitational acceleration signals corresponding to the two display screens at time t and the intermediate angular velocity signals at time t to determine the state of the foldable screen at time t; and determining the included angle corresponding to the foldable screen at time t according to the state of the foldable screen at time t.
