Motorola was the first to ship updates containing new Android versions, while the company operated independently. After Lenovo acquired Motorola, the US company slowed a bit with the updates, but the Moto G4 Plus devices finally got the Android Nougat.
At the moment, the update is available only for unlocked Moto G4 Plus devices in the US. The update is shipping over-the-air and it includes all of the Nougat goodies such as multi-window mode and inline notification replies, as well as Doze improvements making the battery-saving feature even better and battery life even longer.
Android Authority explains that “The update is already being rolled out, but might not be available to all users just yet. It could take a couple of days before Nougat hits all the unlocked Moto G4 Plus smartphones in the country.” So, if you’re living in the US and own the unlocked Moto G4 Plus wait a couple of days (if your device still hasn’t received the update) and Nougat will land on your phone.
The update weighs in at 741 MB so it is advisable to download it over a Wi-Fi connection. You can wait for the notification to appear, or you can try checking for the update manually. If you rely on the automatic update system, you should get the notification once the update is ready to be installed. If you’re impatient, there’s an option to manually check for the update (just visit the update menu inside the Settings app).
