Abstract:
1. A mobile terminal, comprising: a communication unit configured to communicate with at least one external terminal; a memory configured to store at least a first operating system configured to act in a first mode and a second operating system configured to act in a second mode, respectively; and a controller configured to execute the first operating system and to activate the first mode corresponding to the first operating system, to display a first information screen on a display unit corresponding to the activated first mode, to receive a switching signal indicating the first mode is to be switched to the second mode, to perform an authentication procedure for authenticating that the first mode can be switched to the second mode, to activate the second mode and deactivate the first mode when the authentication procedure is validly performed, and to display a second information screen on the display unit corresponding to the second mode and that is different from the first information screen, wherein each of the first information screen and the second information screen comprises at least a first group identifier indicating a first application group corresponding to the first mode or a second group identifier indicating a second application group corresponding to the second mode, wherein the first application group includes at least one application executable in the first mode, and the second application group includes at least one application executable in the second mode, wherein the controller is further configured to control the display unit to display a type identifier only in one group identifier corresponding to a currently activated mode among the first group identifier and the second group identifier, the type identifier indicating the type of the at least one application included in each of the first application group and the second application group, and wherein when the switching signal is received while executing a specific application executable only in the first mode, the controller is further configured to terminate the specific application and responsive to the termination, identify an alternative application similar to the terminated application and execute the alternative application in the second mode.
