Nowadays there are many video calling apps already available in which some become popular and some were flop. Then Google came with the video calling application i.e Google duo. The interface of this application is very neat and easy to use . It is easily available in play store and app store for free. The highlighting feature of this app is that when we make the call, the another person can see us without even answering the call. But in the main segment that is the video quality this app is very poor. The quality of calling is very poor, sometimes it didn’t even show the video of other side, only Audio . Therefore I don’t recommend this application and suggest to use other better application.
