The Moto G 2014, also known as the second-gen Moto G, appears to now be receiving its Marshmallow update. Owners of the phone in select countries have already been able to download the update, but now it appears as though more users are able to install it on their phones. The Marshmallow update brings the new Doze feature, enhanced permission controls and more to the phone.
If you haven't already received an update notification you can head into your Settings, About phone and check manually for the update. Once you've installed it, be sure to let us know how it works out for you.
Thanks for the tip, Grant!
