Prior to this release, a call established over cellular data for example, persisted over cellular data for the duration of the call even if a WIFI network became available. This is undesirable since a WIFI network is usually cheaper and requires less battery power. With this release, an ongoing call will automatically and seamlessly switch to a preferred network type when one becomes available. Network types supported in preferred order are: ETHERNET, WIFI, VPN, and CELLULAR.
