An electronic device includes a touch screen, a user interface module, a detecting module and a process module. The user interface module is configured to create a user interface on the touch screen. A number of hidden active areas are defined in the user interface. A detecting module is configured to detect if the hidden active areas are touched and in what order. A process module is configured to switch the user interface from an operation mode to a test mode after the hidden active areas are touched in a predetermined sequence. |
