The ability to deactivate Voice over Wi-Fi functionality on devices utilizing the Android operating system allows users to prevent calls from being routed through wireless internet networks. For instance, a user experiencing poor call quality due to a weak Wi-Fi signal might choose to prevent call routing through that network.
Deactivating this feature can be beneficial in situations where cellular network connectivity is stronger or more reliable than the available Wi-Fi. This ensures calls are placed and received using the most dependable connection, potentially improving audio clarity and reducing call drops. Historically, cellular networks were the primary method for voice calls; Wi-Fi calling emerged as a supplemental service to improve coverage in areas with weak cellular signals, but it’s not always the optimal choice.
