Hello friends I am going to tell my personal experience with Google duo app today. I am an Android user and I have installed it . If I tell the truth then it’s picture quality and sound are very nice for me. Whenever I make video calls to my friends and relatives I mostly use this app. It’s layout and design is very simple and easy to use there is no complicated option in it . It’s feature and function also very good it’s show the history of the call , easy to invite friend and knock knock option and .etc really I love this app.
