Following last month’s successful soak test, AT&T is now pushing out the hefty Android 4.4.4 over-the-air (OTA) update to all its carrier-branded Moto X handsets currently located in the U.S. Together with the latest build of the open-source operating system, this upgrade brings a modernized dialer application, the ability to pause video recording within the camera app, as well as the habitual bug fixes and stability improvements.
