The latest Android 7.0 Nougat news indicates we could get a final release of the updated OS as early as next month, but only for Nexus phones. While many of the OS’ more significant features have been revealed since Nougat was first announced earlier this year, some details may not be totally clear until the final version actually gets pushed out
One small new feature that hasn’t been revealed seems to be a minor but meaningful change to Android’s focal point “Home” button. In previews for Android 7.0, the button features extra colour, as well as new animations, when used with new Google Now on Tap features.
While nothing has been confirmed, it’s likely that holding down the Home button in Android 7.0 triggers Google Assistant and that the animations (seen above) provide visual feedback showing requests being processed.
It’s quite possible, however, that this could all change before Nougat’s final release. That being said, seeing Google Assistant being directly integrated into the Home button is certainly going to help the average user make use of the feature.
