Motorola has been secretly (soak test) testing Android Nougat in Moto G4 Plus. The update weighing 953MB is currently floating around Brazil.
In early October 2016, Motorola revealed a full list of all handsets which will get Android 7.0 Nougat update. The company revealed that the update will start to roll out in Q4. According to sources, Moto Z and Moto G (4th Gen) series will get Android 7.0 Nougat update.
If you are unaware, soak test signals the fact that only a small subset of users will receive the update. Based on feedback, Motorola is expected to rollout the full release provided there are no critical problems.
