An electronic device comprising:

• a detector capable of detecting a touch operation on an operation surface;
• and
• a memory and at least one processor which function as:
• a control unit configured to perform one or more functions in response to one or more touch operations performed on an operation surface for at least a first period, and
• a setting unit configured to set a response time to a second period longer than the first period in response to a user operation, wherein
• the control unit performs control such that:
• (1) when a first screen is displayed on a display surface in a case where the response time is set to the second period by the setting unit:
• (a) in response to a first touch operation having a duration time on the operation surface of less than the second period, not performing a function corresponding to the first touch operation, and
• (b) in response to a second touch operation having a duration time on the operation surface of at least the second period, performing a first function corresponding to the second touch operation and
• (2) when a second screen is displayed on the display surface in a case where the response time is set to the second period by the setting unit:
• in response to a third touch operation having a duration time on the operation surface of at least the first period and less than the second period, performing a second function.
