I want to be able to record a Google Duo video call, is that possible? Are all the calls recorded?
Google Duo does not record video or audio calls under any circumstances automatically. Many people seem to think Google records all of the above, but that is not true. The app may ask for permissions to your recorder and camera, but that is just for functionality, not invasiveness.
As far as recording audio and video on demand… this feature is not implemented in Google Duo at this time. Please feel free to leave feedback via the Google Duo app to let the developers know this is something you’d like to see in future releases!
