Google Duo Reviews
Most of the reviews for the app is positive
One of the best ones out there. High quality video calls supported all around the world even with the low speed. The best thing is that you can have both 4g and wifi on, and the app works with wifi as default, and switches to 4g immediately if there is any problem. It also lets you know about that, which is very good. So, if you have wifi interruption, you don’t lose the quality while you talking. And it brings back the call on wifi when the speed reaches to an acceptable amount. Totally recommended. I hope they do not ruined it after some time. Maybe it is great since it is new.It has good quality. I just face chatted with my 10 year old daughter in Florida on vacation with her aunt and uncle from Indiana and it worked really great. The sound and picture was wonderful.
