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

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.

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.

will always be ads on display, either the top or bottom of the

background that lead to the quick battery drains.
