A mobile device includes a touch screen, an unlocking key, a function key and a processor. The unlocking key transmits a first command to the processor when pressed. The function key transmits a second command to the processor when pressed. The processor is coupled to the touch screen, the unlocking key and the function key. The processor operates in a standby mode and is configured to: display a first user interface on the touch screen when the processor receives the first command; display a second user interface on the touch screen when the processor receives the second command; switch to a normal work mode when the first user interface of the touch screen detects that the touch gesture is an unlocking touch gesture; and switch to a special work mode and enable a first function when the second user interface of the touch screen detects a first touch gesture.
