If you like the Google Duo app but you do not find many of your contacts using it, then it is not a problem anymore. Google Duo will now allow you to make the calls to even those people in your contact list who have not yet installed the app in their smartphones. This was recently noticed by a Reddit user who then shared his observation.

Similarly, those users who had tested this feature had actually notices that it is workable only with the audio calls. Moreover, the recipients of the calls made from Google Duo will be able to do multiple things, such as hanging up or answering the call, switching the cameras and even muting the calls. This is also done all by the normal Duo users.

Moreover, the users will also be able to block the calls from callers and wont let them contact again. However, if someone does not have Duo but still wants to make the call, then he will first have to install the app in order to make the call.
