Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a continuation application, claiming priority under 35 U.S.C. § 365(c), of an International application No. PCT/KR2024/008894, filed on Jun. 26, 2024, which is based on and claims the benefit of a Korean patent application number 10-2023-0085869, filed on Jul. 3, 2023, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2023-0115514, filed on Aug. 31, 2023, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety. BACKGROUND 1. Field The disclosure relates to an electronic device including a sensor switch and a drop misrecognition prevention method therefor. 2. Description of Related Art Electronic devices are evolving into various structures to meet the needs of users who want various functions. Recently, electronic devices that support the functions of electronic devices through sliding or rolling mechanisms (e.g., slidable electronic devices, rollable electronic devices) have been released. These electronic devices may include a driving structure (e.g., a slide body) designed such that some components of the electronic device are drawn out by the rotational force of a driving unit (e.g., a driving motor), or are seated back by reversing the rotation of the driving unit. However, when electronic devices are subjected to an external impact, such as a drop, while some components of the electronic device are drawn out, the components operatively connected to the driving structure (e.g., flexible display, driving motor, camera lens, electronic components) may be damaged. Moreover, electronic devices may be more vulnerable to damage from external impacts, such as a drop, when some components of the electronic device are drawn out compared to when they are retracted. Electronic devices may require measures to minimize impact by reversing the driving motor to protect the components during a drop state. The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. SUMMARY When an electronic device detects a drop state while some components of the electronic device are drawn out, the electronic device may support a drop detection misrecognition solution function or a drop misrecognition prevention function that determines whether the drop state recognition is a malfunction on the basis of the grip status, and accordingly, either reverses the rotation of the motor or maintains the current state. Meanwhile, the grip sensor used for recognizing the grip status must meet the object recognition distance according to the specific absorption rate (SAR) measurement standard, and so the sensing path may be tuned with defined sensing features. However, since the object recognition distance for the drop misrecognition solution is different from the SAR measurement standard, there is a limitation in utilizing a single grip sensor for both SAR measurement purpose and the drop misrecognition solution purpose. Consequently, the electronic device may require a separate sensing path for the grip sensor, in addition to the sensing path of the grip sensor for SAR measurements, for use in drop detection misrecognition solution (or for drop detection monitoring). However, adding a separate grip sensor to the electronic device may result in hardware constraints not only because of the additional allocation of connection wiring for linking with the control processor but also because of mounting location and increased connection wiring. Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device which proposes a structure and method that can utilize a single grip sensor not only for grip state determination (or SAR measurement) but also for a drop detection misrecognition solution (or drop detection monitoring) by using a sensor switch without adding a separate grip sensor. Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a housing, an antenna, a display, a driving unit that moves at least a portion of the display, a first sensor that identifies a first measurement value for detecting motion information of the electronic device, a second sensor that identifies a second measurement value for detecting grip information of the electronic device, a first circuit and a second circuit that are selectively connectable to the second sensor, a switch by whi
