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 like
Home screen folders and favorites tray
New home screen folders offer a new way for users to group their apps and shortcuts logically, just by dragging one onto another. Also, in All Apps launcher, users can now simply drag an app to get information about it or immediately uninstall it, or disable a pre-installed app.
Resizable widgets
Home screens in Android 4.0 are designed to be content-rich and customizable. Users can do much more than add shortcuts — they can embed live application content directly through interactive widgets.
New lock screen actions
The lock screens now let users do more without unlocking. From the slide lock screen, users can jump directly to the camera for a picture orpull down the notifications window to check for messages. When listening to music, users can even manage music tracks and see album art.
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.
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 users dictate the text they want, for as long as they want, using the language they want. Users 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 users with tiered or metered data plans, Android 4.0 adds new controls for managing network data usage.
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 users 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.
Communication and sharing
Designed for the way people live, Android 4.0 integrates rich social communication and sharing touchpoints across the system, making it easy to talk, email, text, and share.
