knock knock “. It means if you call a person through Duo app, he will see your
live preview without answering your call. It consists of the facility of
recording of our call conservation. The usage of this app is very simple. First
you select one person's phone number in your contact list who has the
accessibility of Duo app and make a video call to him through this app. In case
some of your contacts are not tagged with Duo app, then you a chance to get
connectivity with help of invite icon which is coexisted in this app. Its
abundance is free for installation from Google play store. But this app doesn’t
suits for PC and laptops. But we wish Google will make it as suitable for pc
