The functionality that allows voice calls over a Wi-Fi network on Android devices can be deactivated through the device’s settings. For example, a user experiencing call quality issues on a specific Wi-Fi network might choose to turn off this feature.
Deactivating this feature can be important for several reasons, including troubleshooting call connectivity problems, managing data usage on metered Wi-Fi networks, or ensuring calls are routed through the cellular network in areas with weak or unreliable Wi-Fi signals. Historically, this setting has been included in Android operating systems to offer users greater control over their calling preferences and network utilization.
