Monthly Android distribution numbers show Nougat in use on just .4% of Android devices26
The new numbers for December show a very small .1% decline to 34% for Lollipop. That breaks down to 10.8% for Android 5.0 and 23.2% for Android 5.1%. Combined, the Lollipop build remains the most widely used on Android devices. Second place goes to Android 6.0 Marshmallow, currently installed in 26.3% of Android devices. Phones and tablets powered by Android 4.4 KitKat (24%), Android 4.1.x, 4.2.x and 4.3 Jelly Bean (12.8%), Android 4.0.3, 4.0.4 Ice Cream Sandwich (1.2%) and Android 2.3.3-2.3.7 Gingerbread (1.2%) are next.
That leaves the previously mentioned .4% share belonging to Android 7.0 Nougat and the .1% share still owned by Froyo, Android 2.2. The latter was the first build of Android that supported the use of Adobe Flash on Android phones.
By the way, in case you were wondering, the data is based on devices visiting the Google Play Store during the seven days ended December 5th, 2016.
