Google seems to have started testing Duo group calling and low light mode with a bunch of selected users. Both these features were initially spotted in the APK teardown done by folks over at Android Police. And now, they have received a few screenshots from an anonymous tipster showing both features in action.
The most noteworthy feature between the two is undoubtedly Google Duo group calling. It is a feature which will allow users to video call with multiple people simultaneously. As per the shared screenshots, it supports adding up to seven people within a single group. A user needs to create the group beforehand and once can also give it a name. This way, it will be easier to find the relevant group when you end up creating different groups like for work, family, and friends. Once group(s) has been created, it will become visible on the top of the contacts page.
Next Google Duo feature under work is called Low Light Mode. As the name suggests, it is a mode specifically meant to be used for video calls under low-light conditions. It seems like Google will ask the user before actually enabling the mode in such situations. It is unknown exactly how Google will make videos better for low-light situations but that is something we will know in the near future for sure.
Both these features are currently under testing with a small set of users. It also appears to be a result of the server-side change which means if you don't have it yet, there is no known way of getting these features work. For the time being, we can only expect Google to release them for masses sooner than later.
