WhatsApp returns to the past, call alerts arrive. The news comes with an update currently available only for Android and includes the video call feature. In practice, if you are already engaged in a phone call and you receive another one, a sound will alert giving you the opportunity to choose whether to change or not. One possibility already offered by most telephone operators. However, the call alert on WhatsApp has a difference: it does not allow the first call to be put on hold in favor of the incoming call. You can only decide whether to reject or accept the second call. In this case the instant messaging service will close the phone call in which we were already engaged instead of pausing it. The update is now available for Android devices, it is not clear if and when it will also land on Apple devices.
