Android 4.0 Ice Cream Sandwich introduced a refined user interface with new animations and feedback. It included virtual buttons, improved multitasking, resizable widgets, new lock screen actions, improved text input, powerful voice input, and controls over network data usage. The Retina Display featured in Apple products has very high pixel density that makes images and text look sharp and continuous at any size.

8. 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.

9. 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.

10. Continue ….
 Multitasking is a key strength of Android and it's 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.

11. Android 4
Multitasking

12. 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.

13. 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.

14. 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.

15. Improved text input and
spell-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.

16. 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.

17. 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.

18. Control over network data
 Data usage controls let you monitor total usage by
network type and application and then set limits if
needed.

19. OTHER FEATURES
 Fast & smooth
 Seamlessly take and share photos.
 Android Beam
 The new Google experience on Android-Voice
Search.

20. Google Experience
 Google Now brings you just the right information
at just the right time.
A new look for Search i.e. VOICE SEARCH

21. Continue ….
 Redesigned Gallery app with photo editor
 Live Effects for transforming video
 Powerful web browsing
 Android Beam for NFC-based sharing
 Face Unlock
 Wi-Fi Direct and Bluetooth HDP .

22. 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.

23. • 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

24. 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.

25. 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 iPad's display comes from Samsung
while LG Display make the MacBook Pro display, along
with the iPhone and iPod Touch displays .

26. Retina Display
 SO IT MAKES STUFF LOOK
MAGICALLY BETTER .

27. 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.

28. Continue…
 No detail overlooked.
By developing pixels a mere 78 micrometers wide, Apple
engineers were able to pack four times the number of pixels
into the 3.5-inch (diagonal) screen found on iPhone 4S and
iPhone 4. The resulting pixel density — 326 pixels per inch
— makes text and graphics look smooth and continuous at
any size.

 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 to
achieve a wider viewing angle than on typical LCDs. Which means you
can 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.

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.
