Abstract: An electronic device includes a touch screen, a touch sensor, and a processor. The touch sensor detects an operation feature inputted by the user when the touch screen is in a locked state. The processor receives the operation feature of the user detected by the touch sensor and determines whether the processor stores an operation feature matching the operation feature of the user. When the processor stores an operation feature matching the operation feature of the user, the processor controls the touch screen to switch from the locked state to an unlocked state and actuate an application program or a file corresponding to the operation feature stored in the processor. When the processor does not store an operation feature matching the operation feature of the user, the processor controls the touch screen to keep in the locked state.
