Currently the animation makes Google Now on Tap launch, but with Google Assistant still in development and only expected to be launched alongside the new Nexus phones, it remains possible the animation will give you options that tap into Google Assistant instead.
The reports of customisations for the Nexus series (in this case, via the launcher) is in line with Google CEO Sundar Pichai's statement that the company was planning on getting more opinionated with is Nexus offerings.There remains the possibility that these changes will make their way to Android 7.0 Nougat, or, that the launcher will work on non-Nexus smartphones. As with any other Nougat 7.0 leak, we can't say for sure whether this will make Google's final cut or not but if the company has indeed gone ahead with the development of this animation and wants to promote its Google Assistant feature further.
In other leaks, the search giant is tipped to have changed the colour theme for its 'settings' menu to a UI that is dark grey, blue, and white in colour. The night mode has also been suggested to come under the name 'Night Light'.
The settings tab is suggested to be divided into two sections 'All' and 'Support' in the latest leaks. This particular change has been suggested to be exclusive to the upcoming Nexus devices.Another feature "Quick Screen Check", that has surfaced, will allow the users to check their notifications without waking the phone up fully.
