Definitions

- An electronic device includes a display module, at least one processor operatively connected to the display module, and a memory operatively connected to the at least one processor, the memory comprising: Upon execution, the at least one processor, in response to detecting a first touch event, sets a touch slop that is a criterion for performing a scroll, and controls the current touch every specified time while the first touch event is maintained. Touch information corresponding to a point is acquired, and when it is determined that the touch movement distance exceeds the touch slope based on the acquired touch information, scrolling of the first screen displayed on the display module is initiated, and the scrolling is performed.
