First, he pulled down the notification shade. Instead of the old scattered toggles, there were beautiful, round icons, and he could reply to messages directly from the notification without opening the app. He pressed and held the recent apps button—split-screen mode!

It was a Nougat-powered machine, reborn.

That upgrade had a name: Android 7.0 Nougat.
