Symbian OS was originally developed by Symbian Ltd. as a mobile operating system used primarily in Nokia smartphones. It was formed as an independent consortium in 1998 led by Psion, Nokia, Ericsson, and Motorola. The first Symbian OS phone was the Ericsson R380 in 2000. By 2008, Symbian OS was running on approximately 75% of all mobile phones and had over 82 million cumulative shipments. The operating system was made up of several layers including user interface frameworks, core application frameworks, middleware services, and the kernel. However, Symbian struggled in later years due to poor internet performance, lack of apps, an outdated interface, and issues with its partner network.

2.  Symbian OS is one of Nokia’s mobile
operating system for mobile device
and smartphones with associated
libraries, user interface, frameworks
and reference implementations of
common tools, originally developed
by Symbian Ltd.

3.  Psion founded by David Potter in 1980 launched
the Psion Organizer, the world’s first volume-
produced handheld computer in 1984.
 1997: Psion’s EPOC OS Launched(2 MB memory)
 1998: Symbian consortium and Symbian OS
 Independent of Psion
 Ericsson, Nokia, Motorola, Psion(founders)
 Panasonic, Sony Ericsson, Siemens,
Samsung(shareholders)
 2000: First Symbian OS phone
 Ericsson R380

4.  Symbian OS runs on ~75% of all mobiles.
 Nokia expects the mobile market to exceed 250
million units in 2008
 82.8 million cumulative Symbian OS phone shipments
since the formation of Symbian (as of Q2 2006).
 Symbian C++ gives
 Maximum flexibility
 Speed

5. Same Basis, different feel and look due to different at UI layer:
 S 60: Smartphone with numeric keypad, “phone centric
 S 80: Organizers with full keyboard, “information centric”
e.g. Nokia 9300
 UIQ: mobile phone with pen input, “information centric”
e.g. Sony Ericssion P910

6.  Greater range of application.
 High quality games.
 Better inbuilt web browser.
 Connectivity is not more easier and faster.
 Real Player, Smart movie player etc. sort of application are not
available with java phones.
 You can install software and application of any type.

10.  Frameworks and libraries
for constructing a UI
 Includes the basic class
hierarchies for UI
controls
 Concrete widget classes
used by UI components
 Other frameworks and
utlities
Topmost layer of
Symbian OS, foundation
for variant UI

11.  UI independent support for
application
 Including basic application
frameworks/services
 Application
class(“technology
specification”) logic
 Support for specific
application
 Also some applocation
engines used and extended
by licensees
Generic
Application class specific-
Messaging, browsing
Application specific – Word, Sheet
Engines vs services - evolving

12. o Extends the “base” into a fully
functional OS providing services
across a fully range of
technologies, e.g. graphics,
communications, multimedia,
etc.
o Organised by technology
domain
“Middleware” layer of
Symbian OS, full range
of servers, framework,
and libraries which
extend the base system
into a complete OS
Connectivity
Services
Multimedia &
Graphics Services

13.  It includes the file Server and
User Library
 Plug-In Framework which
manages all plug-in
 Central Repository, DBMS
 Cryptographic services
 Services for a functional port
Lowest level of user-side services,
extends the OS kernel into a
useable(but minimal) system

14.  Bootstraps the physical or emulated
device
 Provides physical and logical device
drivers and other hardware
abstraction
 Create and manages the
fundamental OS kernel abstractions
 Processes, memory
management, scheduling
Kernel layer, contains the OS kernel itself,
device drivers, and similar low-level
components

15.  Poor internet performance
 Failure to gain advantage from being
open-source
 The unsatisfactory app-availability
 Developers started to hate Symbian
 The boring user-interface (UI)
 Symbian did’t target the smartphone
market.
 The unmanageable network of Symbian
partners
