Currently, Facebook videos autoplay on your News Feed as you scroll up and down. While they eat data and various resources, the saving grace is that they are silent -- that is, until now. Facebook has announced several new changes to its video platform today, including a setting that will autoplay videos with sound turned on by default. Android and Me reports: The audio of videos will fade in and out as you're scrolling through your feed. Fortunately, Facebook will at least make it so that audio won't autoplay if your phone is set to silent. If you're not a fan of this change, there will be a setting to turn audio autoplay off. The change is that it will now be on by default for everyone. Other feature introductions are larger previews for vertical videos, a picture-in-picture mode for videos so you can watch and continue scrolling (and even exit the app without interrupting the video on Android), and a Facebook Video app coming to smart TVs.
