Android 4.0 (Ice Cream Sandwich) is the latest version of
the Android platform for phones, tablets, and more. It builds on the things
people love most about Android — easy multitasking, rich notifications,
customizable home screens, resizable widgets, and deep interactivity — and adds
powerful new ways of communicating and sharing.
Re-sizable widgets:
When taking pictures, continuous focus, zero shutter lag
exposure, and decreased shot-to-shot speed help capture clear, precise images.
Stabilized image zoom lets you compose photos and video in the way you want,
including while video is recording. For new flexibility and convenience while
shooting video, you can now take snapshots at full video resolution just by
tapping the screen as video continues to record.
For capturing larger scenes, the Camera introduces a
single-motion panorama mode. In this mode, you start an exposure and then
slowly turn the Camera to encompass as wide a perspective as needed. The Camera
assembles the full range of continuous imagery into a single panoramic photo.
The Gallery app now makes it easier to manage, show, and
share photos and videos. For managing collections, a redesigned album layout
shows many more albums and offers larger thumbnails. There are many ways to
sort albums, including by time, location, people, and tags. To help pictures
look their best, the Gallery now includes a powerful photo editor. You can crop
and rotate pictures, set levels, remove red eyes, add effects, and much more.
After retouching, you can select one or multiple pictures or videos to share
instantly over email, text messaging, bluetooth, social networks, or other
apps.
Refined, evolved User Interface (UI):
Focused on bringing the power of Android to the surface,
Android 4.0 makes common actions more visible and lets you navigate with simple,
intuitive gestures. 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. The System Bar and virtual buttons are present
across all apps, but can be dimmed by applications for full-screen viewing. You
can access each application's contextual options in the Action Bar, displayed
at the top (and sometimes also at the bottom) of the screen.
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. The list
pops up to show thumbnail images of apps used recently — tapping a thumbnail
switches to the app.

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. On smaller-screen devices, notifications appear at the top
of the screen, while on larger-screen devices they appear in the System Bar.
Home screen folders and favorites tray:
New home screen folders offer a new way for you to group
your apps and shortcuts logically, just by dragging one onto another. Also, in
All Apps launcher, you can now simply drag an app to get information about it
or immediately uninstall it, or disable a pre-installed app.
On smaller-screen devices, the home screen now includes a
customizable favorites tray visible from all home screens. You can drag apps,
shortcuts, folders, and other priority items in or out of the favorites tray
for instant access from any home screen.
 |
| Jump to the camera or notifications without unlocking |
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 let you check
email, flip through a calendar, play music, check social streams, and more —
right from the home screen, without having to launch apps. 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.
Swipe to dismiss notifications, tasks, and browser tabs:
Android 4.0 makes managing notifications, recent apps, and
browser tabs even easier. You can now dismiss individual notifications, apps
from the Recent Apps list, and browser tabs with a simple swipe of a finger.
Improved text input and spell-checking:
 |
| Spell checker helps you find error and fix them faster |
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.
To fix misspelled words more easily, Android 4.0 adds a
spell-checker that locates and underlines errors and suggests replacement
words. With one tap, you can choose from multiple spelling suggestions, delete
a word, or add it to the dictionary. You can even tap to see replacement
suggestions for words that are spelled correctly. For specialized features or
additional languages, you can now download and install third-party
dictionaries, spell-checkers, and other text services.
Powerful voice input engine:
 |
| A powerful voice engine allows you to dictate continuosly |
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. As the voice input engine
enters text, it underlines possible dictation errors in gray. After dictating,
you can tap the underlined words to quickly replace them from a list of
suggestions.
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.
Designed for accessibility:
A variety of new features greatly enhance the accessibility
of Android 4.0 for blind or visually impaired users. Most important is a new
explore-by-touch mode that lets you navigate without having to see the screen.
Touching the screen once triggers audible feedback that identifies the UI
component below; a second touch in the same component activates it with a full
touch event. The new mode is especially important to support users on new
devices that use virtual buttons in the System Bar, rather than dedicated
hardware buttons or trackballs. Also, standard apps are updated to offer an
improved accessibility experience. The Browser supports a script-based screen
reader for reading favorite web content and navigating sites. For improved
readability, you can also increase the default font size used across the
system.
The accessibility experience begins at first setup — a
simple touch gesture during setup (clockwise square from upper left) activates
all accessibility features and loads a setup tutorial. Once accessibility
features are active, everything visible on the screen can be spoken aloud by
the standard screen reader.
Communication and sharing
People and profiles:
Throughout the system, your social groups, profiles, and
contacts are linked together and integrated for easy accessibility. At the
center is a new People app that offers richer profile information, including a
large profile picture, phone numbers, addresses and accounts, status updates,
events, and a new button for connecting on integrated social networks.
Your contact information is stored in a new "Me"
profile, allowing easier sharing with apps and people. All of your integrated
contacts are displayed in an easy to manage list, including controls over which
contacts are shown from any integrated account or social network. Wherever you
navigate across the system, tapping a profile photo displays Quick Contacts, with
large profile pictures, shortcuts to phone numbers, text messaging, and more.
Unified calendar, visual voicemail:
To help organize appointments and events, an updated
Calendar app brings together personal, work, school, and social agendas. With
user permission, other applications can contribute events to the calendar and
manage reminders, for an integrated view across multiple calendar providers.
The app is redesigned to let you manage events more easily. Calendars are
color-coded and you can swipe left or right to change dates and pinch to zoom
in or out agendas.
In the phone app, a new visual voicemail features integrates
incoming messages, voice transcriptions, and audio files from one or more
providers. Third-party applications can integrate with the Phone app to add
your own voice messages, transcriptions, and more to the visual voicemail
inbox.
Rich and versatile camera capabilities:
The Camera app includes many new features that let you
capture special moments with great photos and videos. After capturing images,
you can edit and share them easily with friends.
When taking pictures, continuous focus, zero shutter lag
exposure, and decreased shot-to-shot speed help capture clear, precise images.
Stabilized image zoom lets you compose photos and video in the way you want,
including while video is recording. For new flexibility and convenience while
shooting video, you can now take snapshots at full video resolution just by
tapping the screen as video continues to record.
To make it easier to take great pictures of people, built-in
face detection locates faces in the frame and automatically sets focus. For
more control, you can tap to focus anywhere in the preview image.
For capturing larger scenes, the Camera introduces a
single-motion panorama mode. In this mode, you start an exposure and then
slowly turn the Camera to encompass as wide a perspective as needed. The Camera
assembles the full range of continuous imagery into a single panoramic photo.
After taking a picture or video, you can quickly share it by
email, text message, bluetooth, social networks, and more, just by tapping the
thumbnail in the camera controls.
Redesigned Gallery app with photo editor:
The Gallery app now makes it easier to manage, show, and
share photos and videos. For managing collections, a redesigned album layout
shows many more albums and offers larger thumbnails. There are many ways to
sort albums, including by time, location, people, and tags. To help pictures
look their best, the Gallery now includes a powerful photo editor. You can crop
and rotate pictures, set levels, remove red eyes, add effects, and much more.
After retouching, you can select one or multiple pictures or videos to share
instantly over email, text messaging, bluetooth, social networks, or other
apps.
An improved Picture Gallery widget lets you look at pictures
directly on the home screen. The widget can display pictures from a selected
album, shuffle pictures from all albums, or show a single image. After adding
the widget to the home screen, you can flick through the photo stacks to locate
the image you want, then tap to load it in Gallery.
Live Effects for transforming video:
Live Effects is a collection of graphical transformations
that add interest and fun to videos captured in the Camera app. For example, you
can change the background behind them to any stock or custom image, for just
the right setting when shooting video. Also available for video is Silly Faces,
a set of morphing effects that use state-of-the-art face recognition and GPU
filters to transform facial features. For example, you can use effects such as
small eyes, big mouth, big nose, face squeeze, and more. Outside of the Camera
app, Live Effects is available during video chat in the Google Talk app.
Sharing with screenshot:
You can now share what's on your screens more easily by
taking screenshots. Hardware buttons let them snap a screenshot and store it
locally. Afterward, you can view, edit, and share the screen shot in Gallery or
a similar app.
Cloud-connected experience
Android has always been cloud-connected, letting you browse
the web and sync photos, apps, games, email, and contacts — wherever you are
and across all of your devices. Android 4.0 adds new browsing and email
capabilities to let you take even more with them and keep communication
organized.
Powerful web browsing:
 |
| Browser Tab Menu helps you switch quickly between the tabs |
The Android Browser offers an experience that’s as rich and
convenient as a desktop browser. It lets you instantly sync and manage Google
Chrome bookmarks from all of your accounts, jump to your favorite content
faster, and even save it for reading later in case there's no network
available.
To get the most out of web content, you can now request full
desktop versions of web sites, rather than their mobile versions. You can set
your preference for web sites separately for each browser tab. For longer
content, you can save a copy for offline reading. To find and open saved pages,
you can browse a visual list that’s included with browser bookmarks and
history. For better readability and accessibility, you can increase the
browser’s zoom levels and override the system default text sizes.
Across all types of content, the Android Browser offers
dramatically improved page rendering performance through updated versions of
the WebKit core and the V8 Crankshaft compilation engine for JavaScript. In
benchmarks run on a Nexus S device, the Android 4.0 browser showed an
improvement of nearly 220% over the Android 2.3 browser in the V8 Benchmark
Suite and more than 35% in the SunSpider 9.1 JavaScript Benchmark. When run on
a Galaxy Nexus device, the Android 4.0 browser showed improvement of nearly
550% in the V8 benchmark and nearly 70% in the SunSpider benchmark.
Improved email:
In Android 4.0, email is easier to send, read, and manage.
For composing email, improved auto-completion of recipients helps with finding
and adding frequent contacts more quickly. For easier input of frequent text,
you can now create quick responses and store them in the app, then enter them
from a convenient menu when composing. When replying to a message, you can now
toggle the message to Reply All and Forward without changing screens.
For easier browsing across accounts and labels, the app adds
an integrated menu of accounts and recent labels. To help you locate and
organize IMAP and Exchange email, the Email app now supports nested mail
subfolders, each with synchronization rules. You can also search across folders
on the server, for faster results.
For enterprises, the Email app supports EAS v14. It supports
EAS certificate authentication, provides ABQ strings for device type and mode,
and allows automatic sync to be disabled while roaming. Administrators can also
limit attachment size or disable attachments.
For keeping track of incoming email more easily, a resizable
Email widget lets you flick through recent email right from the home screen,
then jump into the Email app to compose or reply.
Innovation
Android is continuously driving innovation forward, pushing
the boundaries of communication and sharing with new capabilities and interactions.
Android Beam for NFC-based sharing:
Android Beam is an innovative, convenient feature for
sharing across two NFC-enabled devices, It lets people instantly exchange
favorite apps, contacts, music, videos — almost anything. It’s incredibly
simple and convenient to use — there’s no menu to open, application to launch,
or pairing needed. Just touch one Android-powered phone to another, then tap to
send.
For sharing apps, Android Beam pushes a link to the app's
details page in Android Market. On the other device, the Market app launches
and loads the details page, for easy downloading of the app. Individual apps
can build on Android Beam to add other types of interactions, such as passing
game scores, initiating a multiplayer game or chat, and more.
Face Unlock:
Android 4.0 introduces a completely new approach to securing
a device, making each person's device even more personal — Face Unlock is a new
screen-lock option that lets you unlock your device with your face. It takes
advantage of the device front-facing camera and state-of-the-art facial
recognition technology to register a face during setup and then to recognize it
again when unlocking the device. Just hold your device in front of your face to
unlock, or use a backup PIN or pattern.
Wi-Fi Direct and Bluetooth HDP:
Support for Wi-Fi Direct lets you connect directly to nearby
peer devices over Wi-Fi, for more reliable, higher-speed communication. No
internet connection or tethering is needed. Through third-party apps, you can
connect to compatible devices to take advantage of new features such as instant
sharing of files, photos, or other media; streaming video or audio from another
device; or connecting to compatible printers or other devices.
Android 4.0 also introduces built-in support for connecting
to Bluetooth Health Device Profile (HDP) devices. With support from third-party
apps, you can connect to wireless medical devices and sensors in hospitals,
fitness centers, homes, and elsewhere.
