  2. 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. 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. 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. 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. MOHAMMED RAFNAS KALATHIL 16
  17. 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. 18.  The best way to reduce a devices vulnerability to malware attacks is to install the most recent versions of operating systems which include security patches. The only mobile platform other than Apples iOS without reports of malware so far is HPs (formerly Palms) webOS, but this may be explained by its relatively low adoption rate.
