The new data shows that the adoption of latest Android Nougat operating system reached a high of 11.5%, but only 0.9% of devices are running Android 7.1, as the rest of 10.5% still run Android 7.0. However, it looks like Android 6.0 Marshmallow is still king, running on 31.8% of the devices that visited Google Play Store in the last week. On the third place is Android Lollipop, which appears to run on 30,1% of the devices that are active on the market. From this, 22.3% of devices run Android 5.1 Lollipop and only 7.8% Android 5.0 Lollipop. But what should scare Google is that 17.1% of devices are still running the very old Android 4.4 KitKat operating system.
