a proximity sensor disposed behind the display, the proximity sensor comprising a light emitting unit configured to emit and a light receiving unit configured to receive a light of a specific wavelength band;
a memory storing instructions; and
a processor configured to execute the instructions to:
establish a call comprising an incoming call or an outgoing call;
during the call:
deactivate a set area of the display or display the set area of the display in a specific color;
