Google Duo quickly climbed to the number one free app on Google Play within two days of its initial release, but it fell to the 127th place not long after

In an email sent to Android phone manufacturers on October 5, 2016, Google announced that, starting December 1, 2016, Google Duo will replace Hangouts within the suite of Google apps Android phone makers must pre-install on devices, with Hangouts instead becoming an optional app for phone makers to pre-install


Google advertises several features of the app:

  • HD 720p video
  • Optimized for low bandwidth mobile networks The app optimizes WebRTC and uses QUIC over UDP Optimisation is further achieved through the degradation of video quality through monitoring network quality
  • "Knock Knock" – an Android-only feature which shows a live preview of the caller before the recipient picks up, which Google says is to "make calls feel more like an invitation rather than an interruption"
  • End-to-end encryption by default
  • Google Assistant support
  • Use of phone numbers to allow users to easily call people from their contact list
  • Automatic switching between Wi-Fi and mobile data
