Over a month after Motorola officially announced the global roll out of the Moto Z and Moto Z Force Nougat update, the update has started hitting European Moto Z units. Arriving as version NPL25.86-15, the Android 7.0 update weighs in at around 1.5GB. The update also brings compatibility with Google's Android-powered VR platform Daydream. As is usually the case with OTA roll outs, it may take sometime before the update notification pops up on your device's screen. You can manually check for the update by heading to your handset's Settings menu. Via
