Android is an operating system intended for mobile devices such as smart phones and tablet computers and more recently used in car other electronic devices such as media players, VOIP phones, Car dashboards and even refrigerators and Micro Waves. It is developed by the Open Handset Alliance led by Google.
Before 2007, Android would have meant a completely different topic, a robot built in the image of humans.
Google purchased the initial developer of the software, Android Inc., in 2005. The Open handset alliance led by Google itself consisting of major tech companies was created to further the OS.
The first commercial product was the T-Mobile G1 smartphone manufactured by HTC. It was released October 2008 for T-mobile. It had the Android OS platform version 1.0. The OS lacked many of the refinements that the current day versions have. In fact the phone saw a major improvement in performance when it was updated with OS version 1.5 (Cupcake).
The 1.5 update brought in many enhancements like automatic screen orientation using the accelerometer and improved Bluetooth functionality.
The phone got mixed reviews. Cnet commented that the Phone was not really suitable for mainstream consumers and business users.
