Introduction to Android 4.0 There are three things that you must know about Ice Cream Sandwich. First, Ice Cream Sandwich is not a food that you can eat as a dessert. For people who knows about nowadays technology, they know that Ice Cream Sandwich, is a type of operating system. Second, Ice Cream Sandwich is a nickname of an operating system, Android 4.0 used in smartphone, mobile phone, and tablet. In these, Ice Cream Sandwich is used to control hardware function of your device and provide general services of your applications. Last, you must know why Android 4.0 is called Ice Cream Sandwich, it’s because Android’s major update all have dessert code names starting in alphabetical order. They are Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, and Ice Cream Sandwich. Latest OS is Jelly Bean which is the fastest and smoothest version of Android yet.
Refined, evolved UI Refined animations and feedback throughout the system make interactions engaging and interesting. An entirely new typeface optimized for high- resolution screens improves readability and brings a polished, modern feel to the user interface. Virtual buttons in the System Bar let you navigate instantly to Back, Home, and Recent Apps.
Continue …. Multitasking is a key strength of Android and its made even easier and more visual on Android 4.0. The Recent Apps button lets you jump instantly from one task to another using the list in the System Bar. Rich and interactive notifications let you keep in constant touch with incoming messages, play music tracks, see real-time updates from apps, and much more.
Resizable widgets Home screens in Android 4.0 are designed to be content-rich and customizable. You can do much more than add shortcuts — you can embed live application content directly through interactive widgets. Widgets are resizable, so you can expand them to show more content or shrink them to save space.
New lock screen actions The lock screens now let you do more without unlocking. From the slide lock screen, you can jump directly to the camera for a picture or pull down the notifications window to check for messages. When listening to music, you can even manage music tracks and see album art.
Quick responses for incoming calls When an incoming call arrives, you can now quickly respond by text message, without needing to pick up the call or unlock the device. On the incoming call screen, you simply slide a control to see a list of text responses and then tap to send and end the call. You can add your own responses and manage the list from the Settings app.
Improved text input andspell-checking The soft keyboard in Android 4.0 makes text input even faster and more accurate. Error correction and word suggestion are improved through a new set of default dictionaries and more accurate heuristics for handling cases such as double-typed characters, skipped letters, and omitted spaces. Word suggestion is also improved and the suggestion strip is simplified to show only three words at a time.
Powerful voice input engine Android 4.0 introduces a powerful new voice input engine that offers a continuous "open microphone" experience and streaming voice recognition. The new voice input engine lets you dictate the text you want, for as long as you want, using the language you want. You can speak continously for a prolonged time, even pausing for intervals if needed, and dictate punctuation to create correct sentences.
Control over network data Mobile devices can make extensive use of network data for streaming content, synchronizing data, downloading apps, and more. To meet the needs of you with tiered or metered data plans, Android 4.0 adds new controls for managing network data usage. In the Settings app, colorful charts show the total data usage on each network type (mobile or Wi-Fi), as well as amount of data used by each running application. Based on your data plan, you can optionally set warning levels or hard limits on data usage or disable mobile data altogether. You can also manage the background data used by individual applications as needed.
Control over network data Data usage controls let you monitor total usage by network type and application and then set limits if needed.

Limitations :• First, the disadvantage is face unlock. Face unlock is the new feature from operating system ICS. The disadvantage is, smartphone can be opened by someone using a photo of smartphone owner .• Second, the disadvantage is minimum requirement. For using Operating System Ice Cream Sandwich, smartphone must be have minimum 1Ghz processor and 512 MB RAM.• The other disadvantage of Android 4.0 is that older Android devices will not be upgradable to the Ice Cream Sandwich.
• Google Android Sales to Overtake iPhone and Tablets by the end of 2012.• Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android .• Android was developed with multiple-processor utilization in mind. It’s simple for Android developers to program for a phone with 2, 4, or even 32 processing cores without having to write a single extra line of code.• By the end of 2012, new devices will be released with up to eight processing cores with clock speeds in excess of 2 GHz. This means longer battery life, as a phone with multiple cores can do more calculations quicker with less energy.More Android devices are coming and some will push the envelope even
Conclusion All-in-all, I would say that the latest offering from Android, the Android 4.0 Ice Cream Sandwich is definitely worth more than just a look. Offering variety of powerful features and functionalities, this is one mobile platform that developers are going to love to develop apps for. By and by, there will be more devices powered by Android 4.0 and that is when its true potential will be fully released to the world.
WHAT’S A RETINA DISPLAY? High Resolution Screen Technology introduced by Apple. Provides greater pixel density and higher contrast ratios. The term is used for several Apple products, including the iPhone, iPod Touch, iPad, and MacBook Pro. The displays are manufactured by different suppliers. Currently, the iPads display comes from Samsung while LG Display make the MacBook Pro display, along with the iPhone and iPod Touch displays .
Retina Display SO IT MAKES STUFF LOOK MAGICALLY BETTER .
FEATURES The sharpest, most vibrant, highest-resolution phone screen ever. Everything you see and do on iPhone 4S looks amazing. That’s because the Retina display’s pixel density is so high, your eye is unable to distinguish individual pixels. Which means text in books, web pages, and email is crisp at any size. Images in games, movies, and photos pop off the screen. And everything is sharper.
Continue… No detail overlooked.By developing pixels a mere 78 micrometers wide, Appleengineers were able to pack four times the number of pixelsinto the 3.5-inch (diagonal) screen found on iPhone 4S andiPhone 4. The resulting pixel density — 326 pixels per inch— makes text and graphics look smooth and continuous atany size.
Continue… Brilliant no matter how you look at it.The Retina display uses technology called IPS (in-plane switching) —the same technology used in the Apple LED Cinema Display and iPad toachieve a wider viewing angle than on typical LCDs. Which means youcan hold iPhone almost any way you want and still get a brilliant picture. In addition, the Retina display offers four times the contrast ratio of previous displays, so whites are brighter, blacks are darker, and everything is more beautiful.
Continue… Advancements in the glass And under it. Made from the same materials used in helicopters and high-speed trains, the Retina display glass is chemically strengthened to be harder, more scratch resistant, and more durable than ever. The glass also features an oil- resistant coating that helps keep the screen clean. The Retina display includes LED backlighting and an ambient light sensor that intelligently adjusts the brightness of the screen for optimal viewing and battery life. When you lift iPhone to your ear for a phone call, a proximity sensor immediately turns off the display to save power and prevent accidental dialing.
