 Definition: Mobile operating system

 History

 Types of mobile operating systems

 Comparison

 A mobile operating system (mobile OS) is the
operating system that controls a smartphone, tablet,
PDA, or other mobile device.

 Modern mobile operating systems combine the
features of a personal computer operating system
with touchscreen, cellular, Bluetooth, Wi-Fi, GPS
mobile navigation, camera, video camera, speech
recognition, voice recorder, music player, Near field
communication, personal digital assistant (PDA), and
other features.

The first smartphone, the IBM Simon, had a touchscreen,
email, and PDA features.

 Palm Pilot 1000 personal digital assistant is introduced
with the Palm OS mobile operating system.
 First Windows CE Handheld PC devices are introduced.

Symbian became the first modern mobile OS on a
smartphone with the launch of the Ericsson R380

 Microsoft's first Windows CE (Pocket PC) smartphones
are introduced.
 BlackBerry releases its first smartphone.

 Apple iPhone with iOS introduced as an iPod, "mobile
phone" and "internet communicator”.
 Open Handset Alliance (OHA) formed by Google, HTC,
Sony, Dell, Intel, Motorola, Samsung, LG, etc.

OHA releases Android 1.0 with the HTC Dream (T-Mobile
G1) as the first Android phone.

Samsung announces the Bada OS with the introduction of
the Samsung S8500.

The Lenovo K800 will be the first Intel powered
smartphone (Android OS).

In 2006, android, ios, windows phone, and bada did
not yet exist and just 64 million smartphones were
sold of blackberry and symbian OS.

Today, nearly 10 times as many smartphones are
sold and the top mobile operating systems by
market share are android, apple ios, RIM
blackberry, windows phone, and bada.

 LATEST STABLE RELEASE

2.0.3 Software Development
Kit(SDK) / December 16, 2011
Bada 2.0 Home screen

 Samsung's first phone running the bada platform was
the wave S8500.With the release of the Samsung wave,
Samsung opened an international application store,
Samsung apps, for the bada platform.
 Bada, as Samsung defines it, is not an operating system
itself, but a platform with a kernel ( it is a bridge
between applications and the actual data processing
done at the hardware level) configurable architecture,
which allows using either a proprietary real-time
operating system (RTOS) kernel, or the Linux kernel.
 Bada supports many mechanisms to enhance
interaction, which can be incorporated into
applications. These include various sensors such as
motion sensing, vibration control, face detection,
accelerometer, magnetometer, tilt, global positioning
system (GPS), and multi-touch.

 All VOIP over Wi-Fi applications were
banned which means that popular
applications such as Skype cannot be
used. In march 2011 this restriction was
removed, allowing VOIP applications to
run on the platform.

 Bada versions 1.X only allowed one bada
third party application to run at a time.
Multitasking applications was only
possible between the base applications
and one bada application. This limit is
removed since version 2.0

Research In Motion(RIM)

 The operating system provides multitasking and supports specialized
input devices that have been adopted by RIM for use in its
handhelds, particularly the track wheel, trackball, and most
recently, the track pad and touchscreen.
 The BlackBerry platform is perhaps best known for its native
support for corporate email, which allows complete wireless
activation and synchronization with Microsoft Exchange, Lotus
Domino, or Novell GroupWise email, calendar, tasks, notes, and
contacts, when used with BlackBerry Enterprise Server. The
operating system also supports W A P (WIRELESS APPLICATIION
PROTOCOL) 1.2.

 INITIAL RELEASE
1997, at the time simply referred to as EPOC,
was later renamed Symbian OS

C++,

Nokia Belle (Symbian^3)

Home screen displayed by Nokia
N8, running Symbian Belle
Operating System.

 USER INTERFACE
Symbian^3 includes the QT FRAMEWORK(cross-platform application
framework that is widely used for developing application software with a
graphical user interface (GUI)), which is now the recommended user interface
toolkit for new applications. QT can also be installed on older Symbian devices.
Nokia currently recommends that developers use QT QUICK WITH QML, the
new high-level declarative UI and scripting framework for creating visually rich
touchscreen interfaces that allows development, it will be delivered to existing
Symbian^3 devices as a QT update.
 BROWSER

Symbian^3 and earlier have a native WEBKIT based browser; indeed, Symbian
was the first mobile platform to make use of WebKit (in June 2005).Some older
Symbian models have Opera Mobile as their default browser.
Nokia released a new browser with the release of Symbian Anna with improved
speed and an improved user interface.

 MULTIPLE LANGUAGE SUPPORT
 Symbian has strong localization support enabling manufacturers
and 3rd party application developers to localize their Symbian
based products in order to support global distribution.
 Current Symbian release (Symbian Belle) has support for 48
languages, which Nokia makes available on device in language
packs

 APPLICATION DEVELOPMENT
 From 2010, Symbian switched to using standard C++ with QT as
the main SDK, which can be used with either Qt Creator or
Carbide C++.
 Alternative application development can be done using Python,
Adobe Flash Lite or Java ME.

ANDROID MARKET
• Android Market is the online software store developed
by Google for Android devices. An application
program ("app") called "Market" is preinstalled on
most Android devices and allows users to browse and
download apps published by third-party developers,
hosted on Android Market.
• As of October 2011 there were more than 300,000 apps
available for Android, and the estimated number of
applications downloaded from the Android Market as
of December 2011 exceeded 10 billion. The operating
system itself is installed on 130 million total
devices.(Techcrunch-July 18 2011)
• Google has participated in the Android Market by
offering several applications themselves, including
Google Voice (for the Google Voice service), Sky Map
(for watching stars), Finance (for their finance
service), Maps Editor (for their MyMaps service), etc.

SECURITY
• Google has responded by removing malicious apps from
the Android Market, remotely disabling them on infected
devices, and scanning newly-uploaded apps for potentially
malicious software. Several security firms have released
antivirus software for Android devices, in particular,AVG
Technologies,Avast!,F-Secure,Kaspersky,McAfee[and
Symantec.

• Android smartphones have the ability to report the location
of Wi-Fi access points, encountered as phone users move
around, to build vast databases containing the physical
locations of hundreds of millions of such access points.

manipulation, using multi-touch gestures,Interface control
elements consist of sliders, switches, and buttons. The response to
user input is immediate and provides a fluid interface.

The home screen displays application icons and a dock at the
bottom of the screen where users can pin their most frequently
used apps. The home screen appears whenever the user
switches on the device or presses the "Home" button (a physical
button on the device).
