  • Publication number: 20140068327
    Abstract: An apparatus and a method for managing a hang state of a mobile terminal are provided. The apparatus and method receives an input signal from a through an input device, such as a chip, independent of an Application Processor (AP) and detects and resolves the hang state. The apparatus includes an AP; an input device configured to receive an input and transmitting an input signal; an input processor configured to receive the input signal and transmit a notification signal to the AP; and a hang-state processor configured to determine that the AP is in a hang-state as the AP is not processing the input signal and the hang-state processor is further configured to remedy the hang-state of the AP, wherein upon receiving the notification signal the AP requests the input signal from the input processor.
