Disabling the feature that routes phone calls over a Wi-Fi network on an Android device is a straightforward process. This setting, when active, allows calls to be placed and received using a Wi-Fi connection instead of the cellular network. For example, one might deactivate this setting to prioritize call quality when the Wi-Fi signal is weak or unreliable.
Deactivating this function can be beneficial in several situations. It can conserve battery life, particularly when Wi-Fi connectivity is inconsistent, as the device is not constantly searching for and switching between Wi-Fi and cellular networks for call routing. Historically, this feature was introduced to improve call quality in areas with poor cellular coverage, but advancements in cellular technology have diminished the necessity for it in many locations.
