Abstract: A method is provided for folding an electronic device including a first housing and a second housing. The method includes an operation of calculating an angle between the first housing and the second housing. The operation of calculating the angle includes calculating, based on sensing data measured by a first sensor module disposed in the first housing and a second sensor module disposed in the second housing, an angle between the first housing and the second housing. The method further includes an operation of measuring a magnetic force value using a digital Hall sensor when a state of the foldable electronic device corresponding to the calculated angle corresponds to a set condition. The method further includes an operation of setting a first reference value associated with folding the foldable electronic device and a second reference value associated with unfolding the foldable electronic device based on the magnetic force value.

Abstract: An electronic device includes: a housing including a first surface facing a first direction; and a second surface facing a second direction opposite to the first direction, wherein an inner space is formed between the first surface and the second surface; a board disposed in the inner space; a geomagnetic sensor disposed on the board; and a processor. The geomagnetic sensor is configured to detect a first magnetic force, when a first cover part of the cover, including a first magnetic member, is disposed to cover the first surface from the first direction of the electronic device, and detect a second magnetic force, when a second cover part of the cover, including a second magnetic member, is disposed to cover the second surface from the second direction of the electronic device in a state where the first cover part is disposed to cover the first surface from the first direction of the electronic device.
