Android, an open-source operating system developed by Google, was launched on October 22, 2008, with the T-Mobile G1 and has undergone numerous updates since. Key features like multi-touch capability, an on-screen keyboard, and a robust notification system have evolved through various versions, culminating in significant releases like Ice Cream Sandwich and KitKat. The OS has dramatically transformed from simple functionalities to a comprehensive smartphone platform, integrating features such as Google Now and enhanced multitasking.

2. Android, an Open-Source Operating System is made
by Google. This operating system has gone through
some pretty incredible modifications since its debut
on the T-Mobil G1.Without, doubt, no single
consumer technology has evolved as rapidly as the
Smartphone, and Android has been at the very heart
of this evolution.

3.  The era of Android, began on October, 22nd,
2008, when the T-Mobil launched in the
United States. Many of its important key
features that we can’t live without today, were
missing – multi-touch capability, an on-screen
keyboard and paid apps, for instance.

4.  However, these early phones clearly weren’t
without flaws, but it was nearly universally
admitted that Android nailed the notification
system from day one. The secret was in the
G1’s unique status bar, which could be
dragged downward to reveal every notification
with a single list, like text, voicemails,
messages, alarms, and so on. This
fundamental concept lives on even today in
4.0.

5.  Let us see the updates as and when they
occurred:

updates it got along were:
 An on-screen Keyboard
 Extensible Widgets

 Video Capture Playback

7.  V1.6 – Also known as “Donut”, though was not
as big update as Cupcake, but it was
nevertheless a far bigger deal than its 0.1
increments would let on. It made another pass
of minor visual refinements throughout the
platform. Although the news was, it offered
CDMA support, this version of Android was the
initiative to support CDMA platform.

8. V2.0/2.1 – it was named Éclair and was
launched in November 2009. It represented
the most fundamental refresh that Android
