Other than the fact it allows me to perform video calls, I struggle to find anything positive to say about Google Duo. Google halted provisioning of carrier based video calling on Pixel 6 devices, so I'm stuck with it. Audio quality is abysmal, static on all calls. No way to toggle back and forth between a video call and audio only. Both parties stopping their video is NOT the same thing, still a Duo data drain. Color tones tend to vary during calls as well. Miserable experience.
