Android Nougat is currently installed on less than 0.4% of all Android devices
According to data collected by Google between November 1 and November 7, Android 7.0 Nougat is now installed on 0.3% of all Android devices in use around the world. As you probably know, only the LG V20, Nexus devices, and the Pixel C currently run 7.0 Nougat. Android 7.1 Nougat is not featured in Google's chart because it's installed on less than 0.1% of devices (basically, just the Pixel and Pixel XL are included here).
All in all, Android Nougat - 7.0 and 7.1 - can be found on less than 0.4% of devices in the wild. Since it's limited to the LG V20, plus the Nexus and Pixel series for now, we're not exactly shocked to see that the new version of the OS is not yet ready to make a bigger impact.
Meanwhile, Android Lollipop (5.0 and 5.1) still holds the crown with 34.1% of devices being stuck on it, followed by Android 4.4 KitKat at 25.2%, and Android Marshmallow at 24.0%.
With Samsung, LG, Motorola, HTC, and others planning major software updates for the coming months, Android Nougat is likely going to gain a few full percents pretty soon.
