13. LET’S TALK ABOUT SYMBIAN VS ANDROID

14. SYMBIAN’S INTRODUCTION
•The Smartphone operating system Symbian OS is produced by the software
development and licensing company Symbian Ltd.
•Symbian Ltd was established in June 1998 and is headquartered in Southwark in the
UK, and the current CEO is Nigel Clifford.
•Research
•We had in mind Symbian’s background, the whole history and development behind
this operating system, his capabilities, security, performance and so on.
•Hardware support and connectivity were, as well, one of our research points.
•The native language of the Symbian OS is C++, there for, our research will passes
through the programming languages that can be used on Symbian.
•The advantages and limitations will be the last tasks we’ll talk about.

15. VERSIONS HISTORY
• Symbian OS 6.0 and 6.1 (also called ER6 )
• Symbian OS 7.0 and 7.0s

• Symbian OS 9.5

16. 7 REASONS WHY ANDROID OS IS BETTER THAN
SYMBIAN
• Change the defaults
• Browsing
• Multiple Home Screens
• Applications
• Platform Updates
• On screen Keyboards

17. DIFFERENCE BETWEEN ANDROID AND
SYMBIAN DEVELOPMENT
• Android built with JAVA and Symbian Build with C++
• Andorid Development Kit (SDK) is much stable than Symbian(Qt)

26. LET’S TALK ABOUT WP VS ANDROID

27. INTRODUCTION
• Windows Mobile is a mobile operating system developed
by Microsoft that was used in smartphones and mobile devices, but is
being currently phased out to specialized markets. It is superseded
by Windows Phone 7
• The current and last version is "Windows Mobile 6.5". It is based on
the Windows CE 5.2 kernel

WINDOWS PHONE 7
• Streamlined User Interface
• Windows 8 has most innovative
mobile UI and Android on the other
hand has a buttery smooth
navigation
• It has live tiles on home screen
which can be now resized, letting
