Abstract: A handheld electronic device and a physical button operation method are provided. The physical button operation method is adapted to the handheld electronic device that includes a physical button. The method includes the following steps. When an application is executed, the physical button is switched from an initial control mode to an application control mode. When the physical button operates in the application control mode, a press event of the physical button is intercepted. The intercepted press event is mapped to a touch operation event. The application is controlled based on the touch operation event. As a result, the convenience and operational flexibility of operating the application can be significantly improved.
