If you recall, back in October this year, Motorola announced the Nougat update for its Moto G4 and G4 Plus smartphones as well as posted release notes for the update on its India website, leading us to believe that the roll out has begun. That, however, was not the case.
Now, nearly a couple of months later, the update has finally started rolling out. Even a Motorola rep confirmed (third screenshot below) that this is the official roll out.
The update is currently hitting units in India. Arriving as version NPJ25.93-11, it brings along Android version 7.0 and also bumps the security level to November 1. The update is being rolled out in batches, so it may take time before your device gets it.
