Abstract: An electronic device is provided. The device includes a first connector configured to couple with a second connector and including a plurality of contacts separated from each other, and a processor configured to detect an incomplete connection between the first connector and the second connector when an electric current does not flow through at least one of the contacts.

Abstract: An input apparatus of a portable terminal and an input method for compensating an input from a pen to increase the accuracy of the pen are provided. The input apparatus includes a touch panel configured to generate an input signal according to a pen touch, a memory configured to store at least one lookup table in which data for compensating an error of a pen input according to a user's pen usage characteristic is stored, a controller configured to detect an input coordinate of the pen touch on the touch panel and configured to extract compensation data from the lookup table corresponding to the input coordinate to compensate the error of the pen input, and a display unit configured to display a compensated pen input signal.
