  1. 1. THE NEXT
  2. 2.  Introduction to smartphone OS’s  The SYMBIAN OS  The concept of CFW
  3. 3. Mobile phone is an electronic device used for full duplex two way radio telecommunications over a celluar network.
  4. 4. In addition to being a telephone, modern mobile phones also support many additionalservices, and accessories, such as SMS, e-mail, Internet access, gaming, Bluetooth & infrared short range wireless communication, camera, MMS messaging, MP3 player, radio and GPS.
  5. 5. Mobile phone Smart phone
  6. 6. A basic phone has a firmware, firmware is a term often used to denote the fixed, usually rather small, programs and/or data Struct- ures that internally control various electronic devices. Smartphone runs on an opeating system. Efficient utilization of hw resources is an advant- age.
  7. 7. What is a smartphone? A smartphone is a mobile phone that offe- rs more advanced computing ability and Connectivity than a basic mobile phone.
  8. 8. Smartphones may be thought of as handheld computers integrated within a mobile telephone.  They run complete operating system software providing a platform for application developers.  we can consider a smartphone as a Personal Pocket Computer (PPC) with mobile phone functions.
  9. 9. A bit of history… The first smartphone ‘SIMON’ was devolved by IBM in 1992, it had a calendar, contacts, world clock, calculator, notepad, email, fax and game. And believe it or not it was a touch screen it was released in 1993.
  10. 10. The OS Every smartphone runs an os, and just like in pc it acts as an interface between the user and hardware.
  11. 11. The OS’s available  IOS  Android  Blackberry  Symbian  Windows mobile
  12. 12. iOS is Apple's mobile operating system. Developed originally for the iphone.  Apple does not permit the OS to run on third-party hardware.  The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons.
  13. 13. The iphone interface….
  14. 14. Android is based upon a modified version of the Linux kernel. Designed and developed by google.  It has no 3rd party HW restrictions like IOS.  Its also designed with a touch user interface.  Its open source and free.
  15. 15. The os used by BlackBerry devices is a proprietary multitasking environment developed by RIM.  The os is designed for use of input devices such as the track wheel, track ball, and track pad.  It has restrictions in 3rd party app devolpment.
  16. 16. blackberry
  17. 17. Windows Mobile is a mobile os developed by Microsoft that was for use in smart phones. It’s a toned down version of windows os for pc, the os supports all office documents and media codecs.
  18. 18. Did we miss
  19. 19. The os… Symbian os is one of nokia’s mobile os’s, it runs on ARM processors.It is programmed in c++.
  20. 20. Symbian OS was created with three systems design principles in mind:  the integrity and security of user data is paramount,  user time must not be wasted, and  all resources are scarce.
  21. 21.  Symbian uses a microkernel, has a request-and-callback approach to services, and maintains separation between user interface and engine.  The OS is optimised for low-power battery-based devices and for ROM-based systems. Applications, and the OS itself, follow an object-oriented design
  22. 22. Is that all there is..?
  23. 23. The concept of CFW…… CFW (custom firmware) is the next step in personalizing your smartphone. Users can flash their phones with CFW, modified FW’s have lots of advantages…
  24. 24.  Users can modify apps in FW and add custom settings.  Efficient utilization of HW resources.  It allows users to remove unwanted apps from the OS.  Users can add frequently used apps to the FW, making the apps run with less resources.
  25. 25. The basic steps in making a CFW  Extract the original FW.  Add custom settings, apps …..  Repack FW  Flash the phone
  26. 26.  Just like desktops were replaced by laptops & netbooks, the smartphone will replace laptops.  Smartphones offer all the functionalities and processing power of a laptop.  The user gets more battery life and operating speeds.
