• a memory;
• and
• a processor operatively coupled to the display, the AOA antenna, the communication circuitry, and the memory, wherein the memory stores instructions executable by the processor to cause the electronic device to:
• determine a position of the electronic device relative to an external electronic device, using the AOA antenna,
• execute a sharing operation with the external electronic device,
• identify whether the display of the electronic device is disposed in a first state or a second state,
• based on detecting that the display is disposed in the first state, perform a first positioning operation for the external electronic device, and
