Improvements to the dialer mean that users can now look up contacts directly from the dialer application, and the new gallery on the phone allows you to "draw" on your pictures. It also offers advanced cropping techniques as well as allowing you to adjust color, exposure, contrast and more. After the update, you will be able to print pictures, documents, Gmail and more using Google Cloud Print and HP ePrinters. And lastly, the update brings a new version of Hangouts that includes integrated SMS/MMS messaging. To make it your default SMS/MMS application, go to Settings > Wireless > Default SMS app.
The update is 174MB and Motorola suggests that you download it over a Wi-Fi connection in order to save your precious data. In addition, the Google owned company says that your battery should be at least 50% charged.
