Google's Android Phone, iphone, Nokia Symbian

Samsung, HTC, Sony Ericsson and Google's Android Phone


Google Android presents a software stack for mobile devices constituting an operating system, middleware and key applications. The Android SDK provides the necessary tools and APIs required to develop custom applications using the Java programming language. Android OS and Android SDK comes with a set of core applications, all written using the Java programming language, including an email client, SMS program, calendar, maps, browser, contacts, and others.
Advantages of Google Android Phone

Google's Android is much more available and talked about than any other mobile OS. Smartphones, unlike a few years ago, have attracted a mass today who are not professionals but are looking for more entertainment out of their cell phones. Google Android phones have become fairly popular because of the deluge of advantages it offers.
 

 Open Platform:    Google Android with Android OS and Google Android SDK is an open platform, which means that the Google code is available for people to look at and edit for making their projects fairly innovative and gives you quality features for anyone to program them into the system.
    

In addition to this, Google Open Source Platform also indicates that the device could be used on multiple networks. An Android phone makes itself available on most popular networks these days. This helps when you are switching from one to another because you won't have to make a complete change in whatever you are using.
 

    Android OS permits third parties to develop applications for the Android phone which could be installed and used by anyone. This is in contrast to many other platforms which demand a permission in order to install the software. With the Google Android phone, you are free to choose which software you wish to install.
 

    An Android phone comes with a guarantee that it works well with Google products. Google products have a huge customer base for the variety of features and flexibility they offer. Whether it's YouTube, Gmail, Google Docs or any other Google product; an Android phone gives you access to a wide variety of applications which you can comfortably use within your phone and your computer.
 

    Eventually this platform will work on netbook and computers. This means that you could have devices that share the same platform giving you the ability to purchase applications that will work on all your devices.

 

Nokia Symbian

Symbian is a mobile operating system (OS) and computing platform designed for smartphones and currently maintained by Accenture. Symbian was originally developed by Symbian Ltd., as a descendant of Psion's EPOC and runs exclusively on ARM processors, although an unreleased x86 port existed. The current form of Symbian is an open-source platform developed by Symbian Foundation in 2009, as the successor of the original Symbian OS. Symbian was the most popular smartphone OS until the end of 2010, when it was overtaken by Android.
The latest version, Symbian^3, was officially released in Q4 2010, first used in the Nokia N8. In May 2011 an update, Symbian Anna, was officially announced, followed by Nokia Belle (previously Symbian Belle) in August 2011. The latest phone with Symbian is the Nokia 808 PureView, released in June 2012.
On 11 February 2011, Nokia announced that it would migrate from Symbian to Microsoft's Windows Phone OS, after Symbian lost popularity. Nokia CEO Stephen Elop announced Nokia's first Windows phones at Nokia World 2011: the Lumia 800 and Lumia 710. These phones were launched on 14 November 2011. On 22 June 2011 Nokia made an agreement with Accenture for an outsourcing program. Accenture will provide Symbian-based software development and support services to Nokia through 2016; about 2,800 Nokia employees became Accenture employees as of October 2011. The transfer was completed on 30 September 2011

iPhone


iOS (previously iPhone OS) is a mobile operating system developed and distributed by Apple Inc. Originally released in 2007 for the iPhone and iPod Touch, it has been extended to support other Apple devices such as the iPad and Apple TV. Unlike Microsoft's Windows Phone (Windows CE) and Google's Android, Apple does not license iOS for installation on non-Apple hardware. As of September 12, 2012, Apple's App Store contained more than 700,000 iOS applications, which have collectively been downloaded more than 30 billion times. It had a 14.9% share of the smartphone mobile operating system units shipped in the third quarter of 2012, behind only Google's Android. In June 2012, it accounted for 65% of mobile web data consumption (including use on both the iPod Touch and the iPad). At the half of 2012, there were 410 million devices activated. According to the special media event held by Apple on September 12, 2012, 400 million devices have been sold through June 2012.

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. Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching from portrait to landscape mode).

iOS is derived from OS X, with which it shares the Darwin foundation, and is therefore a Unix operating system. iOS is Apple's mobile version of the OS X operating system used on Apple computers.

In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The current version of the operating system (iOS 6.0) dedicates 1-1.5 GB of the device's flash memory for the system partition, using roughly 800 MB of that partition (varying by model) for iOS itself



Conclusion:

  • Android is the First in Ranking
  • IPhone iOS is the Second in Ranking
  • Nokia's OS is third in Ranking
