Google Releases Duo App for One-to-One Video Calls on Smartphones

It also adapts to changing network speeds and conditions and can automatically switch from Wi-Fi to cellular data if a caller starts a chat at home and then heads outside, he said.

The Knock Knock feature was created to "make calls feel more like an invitation rather than an interruption," Uberti noted. "Knock Knock makes video calling more spontaneous and welcoming,...
