Galaxy S4 Mini

AT&T has just released a new firmware for the Samsung Galaxy S4 Mini that delivers support for voice over LTE (VoLTE) calling. Though the update could be downloaded over the air, you'll need to be connected to a WiFi network to do so. In addition to VoLTE support, the update also supports emergency 911 calling without requiring a SIM card to be present.
