In 2016 Google launched video calling app, now google planning to integrate video calling directly into Android.That’s the company’s person-to-person mobile video calling solution, announced alongside Allo back at Google I/O 2016. Its mentioned in googles blog post, that the company wants to roll out video calling to Android users. Soon it will be available in latest Android featuring devices. This feature is headed to the first-generation Pixel, Android One, and Nexus devices. It will also be available for the Pixel 2.
“We’re working with our carrier and device partners to bring this experience to more Android devices over time,” Google explained. When the video call is placed, it’ll go through your carrier’s ViLTE service (video over LTE). If you’re not on a carrier with that type of service, Google will instead put the call through Duo, meaning both the sender and the receiver needs to have the app installed.
