Abstract
This generation, phonemakers developed their products more useful and more attractive and thus smartphones are born two of the biggest competitors of today : The Google Corporation that developed the well known operating system for smartphones called “Android OS” while the Apple Corporation and CISCO used their resources to build their compact operating system called “iOS”. At first iOS was called “iPhone OS” because it is only dedicated for the apple smartphone called the iPhone but now, almost of the Apple devices uses the iOS like iPad, iPod touch and Apple TV. This paper makes a comparison on what operating system is most suitable for multimedia, multi-tasking, connectivity and communication. The review examines in depth the pros and cons of the current boom in information revolution focused on smartphones, its advantages and its limitations.

Which is smarter iOS or Android OS?

First, Android operating system, the world's most popular mobile platform. Android powers millions of phones, tablets, and other devices and brings the power of Google and the web into your hands.With an amazingly fast browser, cloud sync, multi-tasking, easy ways to connect & share and the latest Google apps (and thousands of other apps available on Android Market) your Android powered device is beyond smart. Second, An “iOperating System” is the system that all other programs “Operate in”. An iPhone, iPod Touch or iPad is really a portable computer. iOS (formerly iPhone OS) is Apple Inc.'s mobile operating system. Originally developed for the iPhone, it has since been extended to support other Apple, Inc. devices such as the iPod Touch, iPad, and Apple TV. Apple, Inc. does not license iOS for installation on non-Apple hardware. As of October 4, 2011, Apple, Inc.'s App Store contained more than 500,000 iOS applications, which have collectively been downloaded more than 18 billion times. It had a 26% share of the smartphone operating system units sold in the last quarter of 2010, behind both Google's Android. In May 2010 in the USA, it accounted for 59% of mobile web data consumption (including use on both the iPod Touch and the iPad).This review considers whether what’s best to use by responding by following questions: 1. What are the similarities and differences of iOS and Android OS? 2. Today most of the smartphones are smarter, what is the history and versions of iOS and Android OS? 3. What are the phone manufacturers using iOS and Android OS? 4. Which is preferred between iOS and Android OS?

Level APP or Experience? Page 4 What are the similarities and differences of iOS & Android OS?
Android and iOS are starting to look a lot like each other. Let's see what's different and what's similar.

iOS notification area Android notification area
The Notification Center is a brand new feature in iOS 5 that have been around in Android since it's very beginning. And it's great. Simply swipe your finger from the top of your screen to see notifications; anything from messages, emails and facebook happenings. Of course this exists in Android 4 still, with improvements such as availability even when the phone is locked and you can remove notifications by swiping them to the right. Also you now see pictures of the people that might have called or messaged you.

Unlock With Your Picture
A very neat new feature in Android 4 is the ability to unlock your phone without a code. Instead, take a photo of yourself and the phone will analyze the picture and decide if it's you, and if it is--it'll unlock the phone. This feature is unique to Android 4. At least for now

Print Screen

Level APP or Experience? Page 5
Android users can now take print screen regardless of phone, by pressing volume down and the power button a screenshot is taken. This is something that iOS have had for a long time, by pressing down the power and home button at the same time. While this has existed in some of the android versions before, it hasn't been universal till now.

Hardware-accelerated User Interface
The user interface of Android has long been referred to as sluggish, this is due to Android previously having the CPU handling the user interface, but with Android 4.0 it's the GPU (graphic processor) who takes over this task. iOS have had it this way for a long time now and the result for Android users sould be a snappier user interface, much like the iOS already is,.

Widgets
Another new feature of Android 4 is that widgets are presented in the same fashion as apple's apps, but in a separate tab. This makes it so you have a much better overview of your widgets. iOS 5 does not have widgets

Voice Control
Siri in the iOS 5 allow you to ask questions and talk to your iPhone in a very natural way. Ask what the time is, the weather, find a nearby mexican restaurants and even see if Siri wants to start your car (she can't). Android does not have this, instead you have to be content with simple voice recognition which can detect some commands that you give it, but it's not even close to as advanced as Siri for the iOS.

Folders
To create folders is just as easy on both platforms now, since Android 4 have taken the iOS 5 solution. Now a folder is created if you drag an app over another.

Data Traffic

Level APP or Experience? Page 6
Android 4 have another new feature, the ability to control how much data traffic the phone are allowed to use. If you have a plan with limited amount of data traffic, this is good. You can add in warnings and limits. iOS 5 does not have this.

Today most of the smartphones are smarter, what is the history and versions of iOS and Android OS? Android OS Overview
The version history of the Android operating system began with the release of the Android 1.0 beta in November 2007. Android is a mobile operating system developed by Google and the Open Handset Alliance, and has seen a number of updates to its base operating system since its original release. These updates typically fix bugs and add new features. Since April 2009, each
