operating system for digital cameras, but then it was realised that
market for such devices was not large enough so they diverted
their attention to producing a Smartphone operating system.

$ and unveiled its distribution in 2007 with formation of Open
Handset Alliance led by Google.

Dream, released on October 22, 2008 With Android Version 1.0

7. Revolution in Mobile Experience
• Before invention of mobile OS, only technological device that
required an operating system was a personal computer. Initially it
was just one or two high-end mobile phones that ran on operating
systems, but with the success of those particular models, more
models started using Smartphone operating systems.
• One Smartphone operating system that has truly revolutionized
the whole idea of a mobile phone is Android. The first mobile
phone to run on android OS was ‘HTC DREAM’. After the
success of Android based HTC(Dream), more and more
Smartphone manufacturers joined the android project and the
members of the Open Handset Alliance (OHA) increased. This
resulted in Android becoming the most widely used Smartphone
OS in the market.

8. Revolution in Mobile Experience
• The open source and flexible nature of Android allows the
developers and device manufacturers to modify the software
according to their needs, As a result of this constant
development and innovation, Android has been adapted to work
on technological devices other than smart phones.
• Android devices are much more cost effective than its rivals and
offer a more stimulating and fulfilling user experience, thus,
making Android the most preferred choice by users.
• Android has become the core operating systems of many other
devices like Smart books , Wristwatches , Car, CD/DVD players
, Camera and other devices

notification system which allows them to be accessed through
the lock screen and displayed within apps as banners at the
top of the screen. According to Google, it has been designed
to manage memory (RAM) to keep the power consumption at
minimum, so more battery.

15. Android Rooting
Android Rooting is the process of allowing users of devices
running Android OS to attain privileged control, also known
as root access, of their android system.
It is performed with the goal of overcoming limitations that
manufacturers put on their devices, resulting in the ability to
replace device’s operating system or perform other
operations that are otherwise inaccessible to a normal
android user.
Many manufacturers have tried to make “unrootable” devices
with harsher protections but they are usually still rootable in
some way. There may be no root available for a new device,
but one is usually available in a few weeks.

17. Limitations of Android OS
Android requires an active internet connection. At least there
should be a GPRS internet connection so that the device is
ready to go online according to our needs.
Application in the Android phones can easily be obtained and
for free, but the consequences in each of these applications,
will always be ads on display, either the top or bottom of the
application.
Android operating system has a lot of "process" running in the
background that lead to the quick battery drains.
Making source code available to everyone inevitably invites
the attention of hackers and less secure than other mobile
OS.
