Hey dosto I am with my new review about google duo.It is available only for android software because the developer is google corporation powered by google limited. It is a very interesting video chatting application. With 2G network you can video chat with your friends, family.etc. It is very fast to use and voice and video quality and clarity is so good during chatting. I think it is better than imo and other videos chatting application which are use in 2G networks so must download this application and start video chat with your friends. Thnk you.
Love you friends
