Video frequently gets choppy even with a strong connection on both sides. I never use it unless my phone is plugged in because of the rapid battery drain, which makes the calls awkward. Still, it's the most reliable app I've tried so far for making calls between my Android phone and my Sister's iPhone.
So far I've only used it to call my husband since FB Messenger is too slow, but I like it. It's simple and if both of us have good signal then the picture is perfect. I'm sure it will be improved in the future, but as it is now is wonderful.
It show clear video but many times hangs on slow connections that's irritating. Video quality is better than IMO but please make it it smoother as like IMO on slow connections. Otherwise it has no use. It's frustrating wen it hangs during call. Plz make it better choice for all
The app is stellar overall, with one huge, glaring exception: You have to have the app open to get a video call (Nexus 6P Android 7.1.2 official here) otherwise you'll miss it, and won't get a notification about the missed call until the app is opened. Basically whatever contacts you've added into the app need to notify you via text/phone call that they would like to Duo call with you, and then you wait for the call to come in where apps like Skype will ring through just like a normal phone call, even when allowing Duo to manage phone calls like the normal phone dialer, even with the "Knock Knock" feature enabled. Fix this, and it'll definitely be 5 stars. Edit: even with these latest updates, I still don't get the knock knock of an incoming call on the same device listed above. I have to be in the app for it to alert me. Other people that I call out to on other devices on older versions of Android get the knock.
Way better than hangouts and tango. Just need one other feature. Can you allow answering a video call but allow forcing audio only or add a toggle to turn off video like hangouts. Otherwise fantastically simple and quality video call app.
Nyc app, I'm used this app many times for check quality, Amazing Video quality as well audio Communication between both. Noise ratio between calling is Zero. I'm recommend my frnds.
