Claim of US Patent No. 10,990,200

17. An electronic device, comprising:a housing;
a display exposed through a portion of the housing;
a wireless communication circuit disposed in the housing;
a processor disposed in the housing and operatively connected with the display and the wireless communication circuit; and
a memory operatively connected with the processor, wherein the memory stores instructions executable by the processor to cause the electronic device to:
at a first time point, change the electronic device from a lock state to a unlock state in response to a user's input,
at a second time point after the first time point, change the electronic device from the unlock state to the lock state,
after the second time point, detect an approach of a stylus pen within a predetermined distance from a surface of the display in the lock state, and
change the electronic device from the lock state to the unlock state based at least in part on receiving, through the wireless communication circuit, at a third time point after the second time point, a wireless signal generated by the stylus pen based on the approach of the stylus pen, wherein:
when a state of the electronic device is changed from the unlock state to the lock state at the second time point based on execution of a first application program which is associated with a use of the stylus pen before the second time point, and the state of the electronic device is changed from the lock state to the unlock state at the third time point based on approach of the stylus pen at the third time point, and
when the state of the electronic device is changed from the unlock state to the lock state at the second time point based on execution of a second application program which is not associated with a use of the stylus pen before the second time point, and the state of the electronic device maintains the lock state at the third time point despite the approach of the stylus pen at the third time point.
