Google Duo is optimized for low- bandwidth mobile networks through WebRTC and uses QUIC over UDP. The Google Duo web app will also be redirected to the Google Meet web app. The merger began in August, with the Duo mobile app renamed Meet and the original Meet intended to be phased out. In June 2022, Google reversed course and announced that Duo and Meet would, in fact, be merged. In December 2021 this objective had been dropped, but Duo continued to be available and updated. In August 2020, it was reported that Google was planning to eventually merge Google Duo with the business-oriented Google Meet. In December 2016, Google Duo replaced Hangouts within the suite of Google apps device manufacturers must install in order to gain access to the Google Play Store, with Hangouts instead becoming optional.
