The December update began rolling out on December 6, but Google says some customers reported their calls were being dropped or disconnected. The December update was initially slated to include a range of fixes and improvements, including a fix for an issue causing the Google Assistant to unintentionally start a phone call in certain conditions.  Customers that already received the December software update and are still dealing with dropped calls will have to use the Android Flash Tool and perform a factory reset to revert to the previous software version.  Google launched the Pixel 6 and Pixel 6 Pro back in October, introducing the first smartphone using the Google-designed Tensor chip. With its own hardware and software powering the device, the latest Pixels were designed to serve as Google’s answer to the iPhone. Reviews, however, have been mixed.
