Android's latest version Nougat has finally passed the 1% mark in the Google OS distribution chart. 7.0 and 7.1 combined now represent 1.2% of the total number of devices running Android - more than Froyo and Gingerbread each. Hurrah. Meanwhile, Lollipop remains the OS version most droids have installed, down half a percentage point since last month to 32.7%. Marshmallow is a close second with 30.7% of the market. Compare that to the Apple figures, where the latest iOS 10 powers 76% of devices, and a mere 6% of iPads and iPhones are more than one version behind. Source
