Android (based on the Linux Kernel) is from Google Inc.. It has the largest installed base worldwide on smartphones. Most of Android is free and open source, but a large amount of software on Android devices (such as Play Store, Google Search, Google Play Services, Google Music, and so on) are proprietary and licensed.

Android's releases prior to 2.0 (1.0, 1.5, 1.6) were used exclusively on mobile phones. Android 2.x releases were mostly used for mobile phones but also some tablets. Android 3.0 was a tablet-oriented release and does not officially run on mobile phones. The current Android version is 5.0.

Android's releases are named after sweets or dessert items:

Cupcake (1.5)
Donut (1.6)
Eclair (2.0)
Frozen Yogurt ("Froyo") (2.2)
Ginger Bread (2.3)
Honeycomb (3.0)
Ice Cream Sandwich (4.0)
Jelly Bean (4.1), (4.2), (4.3)
Kit Kat (4.4)
Lollipop (5.0)


Most major mobile service providers carry an Android device. Since HTC Dream was introduced, there has been an explosion in the number of devices that carry Android OS. From second quarter of 2009 to the second quarter of 2010, Android's worldwide market share rose 850% from 1.8% to 17.2%. On November 15, 2011, Android reached 52.5% of the global smartphone market share. On September 2014 Android's global market share rose to 85%********************
