    Abstract: In a method for unlocking an electronic device, the electronic device presents a visual indication as to whether the device is in a locked or an unlocked state. An unlocking icon and a first indication icon are displayed on a display device of the electronic device when the electronic device is locked. In response to detecting a touch signal on the display device, the method determines whether the touch signal is an unlocking signal in relation to the unlocking icon. When the touch signal is the unlocking signal, a touch duration is timed and a second indication icon is displayed on the display device. When the touch duration exceeds a predetermined time, a third indication icon is displayed and the electronic device is unlocked.
