When using Find My iPhone, if you can hear sound when clicked, what might be the issue?

The scenario where you can hear sound when you click the "Find My iPhone" feature suggests that the device is indeed on and connected to the network, indicating that the device is not turned off or in Airplane mode. Additionally, if you can hear the sound, it confirms that the device you are trying to locate is correct and actively responding to the command.

Therefore, the situation described points to the possibility that you may have selected the wrong iPhone from the list. This means that while the feature is functioning properly, it is targeting a different device than intended, explaining why you hear the sound but may not actually be locating the correct iPhone. This understanding highlights the importance of verifying device selection within the "Find My" app to ensure accurate location tracking.
