Abstract
Disclosed is an electronic device including a housing, a display panel which is viewable via a part of the housing, and is configured to detect an input by a stylus pen, a processor operatively connected to the display panel, and a memory operatively connected to the processor, wherein the memory is configured to store instructions which, when executed, enable the processor to receive a signal from the stylus pen via the display panel, determine a strength of the signal, a first phase of the signal, and a location of an input by the stylus pen based on at least the received signal, and adjust a threshold value used for determining a type of an input by the stylus pen based on at least the first phase.
