Motorola has released Android 7.0 Nougat update to Moto Z and Moto Z Force. It came a few days after Verizon variant of the Moto Z, Moto Z Droid and Moto Z Droid Force in the US received the firmware. However, popular mid-range smartphones -- Moto G4 and Moto G4 Plus -- have been left out, upsetting their owners.

But why should the Moto G4 and Moto G4 Plus owners be disappointed with the delay in the roll out of Android 7.0 Nougat as several other handsets, including those belonging to Moto X-series haven't got it?

Well, owners of the Moto G4 and Moto G4 Plus have a reason to be upset. It was the Lenovo-owned company that confirmed in a blog post that it would release Android 7.0 Nougat update to Moto Z and Moto G (4th Gen) devices in the fourth quarter of this year. It gave the impression that the devices would receive the new firmware at around the same time, but that was not to be. The Moto Z handsets have got the OS but it is still not known when it will come to the devices from the Moto G4 series.

Interestingly, it was speculated much before the Moto Z devices received the Android 7.0 Nougat update that the Moto G4 and Moto G4 Plus had already got it (over-the-air) but it turned out to be false. Motorola clarified that it had not seeded the firmware to its devices.

The Moto G4, Moto G4 Plus and Moto G4 Play are expected to be in the next line to get Google's new firmware but it is still not known when it will happen.

Motorola has revealed in a blog post that its devices Moto G (4th Gen), Moto G Plus (4th Gen), Moto G Play (4th Gen), Moto X Pure Edition (3rd Gen), Moto X Style, Moto X Play, Moto X Force, Droid Turbo 2, Droid Maxx 2, Moto Z, Moto Z Droid, Moto Z Force Droid, Moto Z Play, Moto Z Play Droid, and Nexus 6 will receive Android 7.0 Nougat update.
