2.  A Smartphone is a mobile phone built on a mobile
operating system, with more advanced computing
capability and connectivity .
 The first smartphones combined the functions of
a personal digital assistant (PDA) with a mobile phone.
Later models added the functionality of portable media
players, low-end compact digital cameras, pocket video
cameras, and GPS navigation units to form one multi-use
device.
 Many modern smartphones also include high-
resolution touchscreens and web browsers that display
standard web pages as well as mobile-optimized sites.

3.  Design and capabilities of a Mobile OS (Operating System)
is very different than a general purpose OS running on
desktop machines:
 mobile devices have constraints and restrictions on
their physical characteristic such as screen size,
memory, processing power and etc.
 Scarce availability of battery power
 Limited amount of computing and communication
capabilities
 Thus, they need different types of operating systems
depending on the capabilities they support. e.g. a PDA OS
is different from a Smartphone OS.

15.  According to a Readers' Choice Awards survey conducted
by P C Magazine in 2012, iOS and Windows Phone
customers gave their phones a rating of 8.7 on a 0
(extremely dissatisfied) to 10 (extremely satisfied) scale, an
improvement of 0.3 and 0.6 points respectively. Android
received a 7.9 (the same rating it received in 2011), followed
by webOS (7.7), Symbian (7.4) and Blackberry OS (6.8).
 The biggest reasons given by readers when asked why they
chose their mobile phones are as follow: operating system
(51%) and 4G capability (51%) for Android, quality of email
experience (46%) for Blackberry, availability of apps (63%)
for iOS and operating system (78%) for Windows Phone.

16.  The rate of lawsuits, trade complaints, and countersuits
and complaints based on patents and designs, in the
markets for smartphones and devices based
on Smartphone OSes such as Android and iOS, increased
greatly in 2010 as companies engaged in patent wars.
 Smartphone war between Samsung and Apple started
when Apple claimed that the original Galaxy S Android
phone copied its iOS in terms of interface and possibly the
hardware of iPhone 3GS.

17.  As smartphone adoption increases, these devices become
more appealing to attackers who try to infect them
with malicious software(malware).[Smartphone security
literature suggests that smartphone malware can be written
even by average developers.
 Smartphone malware is more easily distributed through
application stores that have minimal or no security
mechanisms, such as app kill switch, review process for
their content, etc
 Often malware is hidden in pirated versions of legitimate
apps, which are then distributed through 3rd party app stores
MOHAMMED RAFNAS KALATHIL 17

18.  The best way to reduce a device's vulnerability to malware
attacks is to install the most recent versions of operating
systems which include security patches.
 The only mobile platform other than Apple's iOS without
reports of malware so far is HP's (formerly Palm's) webOS,
but this may be explained by its relatively low adoption
rate.

 Mozilla's Firefox OS
 Canonical Ltd.'sUbuntu Phone
 Jolla Sailfish
 Tizen

20.  Technology mobile phones become more powerful from
time to time. For sure mobile operating system also
improved to make sure all the application on the devices
run smoothly.
