Surely, many people have already tried the messenger Google Duo. After its release, it allowed communicating only through video calls, but with the latest update, the function of voice calls became available to everyone.Recall that the main feature of Google Duo was the ability to see the interlocutor even before you press the button to accept the call. For those who are used to and like to use the video call this application provided perhaps all the necessary features, but for those who don't want to show their face to the interlocutor - it simply didn't leave much choice. However, back in March of this year, Google representatives announced the imminent implementation of the function of making voice calls in their messenger. Toward the end of last month, users from Brazil were able to try the new feature, and now it was launched worldwide. The switch to select the video or voice call appeared in Google Duo version under the number 9.1.1516. If the appropriate toggle switch does not appear, you should check the version of the installed program and, if necessary, update it. If after installing the current version the changes do not take effect, do not worry: many users report that the switch appears at the top of the screen after some time: from a few seconds to a couple of minutes.
