Tizen Operating System

Tizen is an operatng system as other operating system like Android,Windows & iOS. Tizen provides application development tools based on the JavaScript libraries jQuery and jQuery Mobile. Since version 2.0, a native application framework is also available, based on an Open Services Platform from the Bada platform.HTML5 applications run on Tizen, Android, Firefox OS, Ubuntu Touch, Windows Phone, and webOS without a browser.

In late January 2013, Tizen 2.0 scored highest at the time in an HTML5 test of any browsers. As the old HTML5 tests were phased out on November 13, 2013, Tizen 2.2 fell below BlackBerry 10.2 at 494 out of 555 points. However, as of December 2013 desktop browsers had regained the advantage, and results for Tizen 2.2 on a Samsung device score highest overall in mobile, with a score of 497 points.In May 2013, a community port of Qt to Tizen focused on delivering native GUI controls and integration of Qt with Tizen OS features for smartphones. 

Based on the Qt port to Tizen,Applications based on Qt, GTK+ and EFL frameworks can run on Tizen IVI. While there is no official support for these third-party frameworks, according to the explanation on the Tizen SDK website, Tizen applications for mobile devices can be developed without relying on an official Tizen IDE as long as the application complies with Tizen packaging rules. Extending open source software and patenting the extension is an option that most open source licenses do not restrict.Apple has pursued patent litigation and even transferred some to known trolls to pursue Tizen partners (HTC, LG, Samsung, and more), by early 2014 cross-licensing among hardware manufacturers was happening more broadly. 

A number of components internally developed by Samsung (e.g., boot animation, calendar, task manager, music player applications) are, however, released under the Flora License, essentially a BSD- or Apache-style license except granting patents to "Tizen Certified Platform" only. Flora is not approved by the Open Source Initiative.

Samsung's collaboration with the EFL project, and especially Carsten Haitzler, was known as LiMo for years. It was renamed Tizen when Intel joined the project in September 2011, after leaving the MeeGo project. A common misconception is that Tizen is a continuation of MeeGo. In fact, it builds on Samsung Linux Platform (SLP), a reference implementation delivered within LiMo.

Tizen released version 1.0 named LARKSPUR on April 30,2012.

American wireless carrier Sprint Nextel announced it had agreed to become part of the Tizen Association and planned to include Tizen-powered devices in their future lineup

On May 7, 2012

Tizen released version 2.0 alpha, code-named Magnolia. It offered an enhanced web-based framework with more features, better HTML5/W3C API support and more device APIs, multi-process WebKit2-based web runtime and better security for web applications. Support for OpenGL ES has been enhanced. Newly added platform SDK has been provided to help with platform development based on Open Build Service (OBS) On September 25, 2012

Market Release

• Galaxy Gear smartwatches use Tizen as their operating system

• Allegedly, the first Tizen devices were planned for the second half of 2012

• Tizen services made by Samsung were said to ship in 2013, perhaps in August or September

• Samsung released the firmware source code for their NX200 and NX300 cameras

• Samsung unveiled the Samsung Gear 2 and Gear 2 Neo smartwatches, running Tizen instead of Android (Android was used in the original Samsung Galaxy Gear).

 Tizen Vs Android

• Tizen is much lightweight  as compare to Android due to which it offers faster startup.

• For web browsing Tizen improve scrolling and rendering

• As android OS there is a swip down for notifications is similar in Tizen also

• Tizen offers 3D window effects with support for Apps and Games that require advanced 3D graphic

• Multi tasking and multi touch gestures are supported as just like Android

• Tizen's dynamic box icon can be resized to show more or less information

• Tizen version 3 will support 64 bit processors,which is something that Google is working on for its next Android update

 Challenges

• To reproduce alternatives to all Google services which are integrated within the Android OS

• To develop the Tizen App Store as mobile devices such as smart Phone and tablets live or die based upon the wealth of Apps available to them
