1. Android Beam
This feature makes use of near field communications (NFC) technology to allow users to share information more conveniently. You simply need to tap two compatible devices together and items such as links, contacts and map location will be transferred. You can also share apps, though this doesn’t mean a complete transfer of the application. What happens is that the person receiving the information will be directed to Android Market where he/she can download the app from there.
2. Improved camera app and editing
The camera application in Android 4.0 has been overhauled, adding many new features. The Galaxy Nexus boasts of having “zero shutter lag”, which means the user can take photos continuously, with less risk of missing a shot.
A panorama shot feature has also been added, so you need only to pan the handset across a scene and the phone will stitch together a panoramic shot.
Photo-editing features have also been added so basic tweaks like crop, rotate and sharpen can be easily done. In addition, there are also filters so creative effects can be added. Some manufacturers (HTC, in its Sense UI, for example) have previously added these features in their custom camera apps, but having them native in Android will definitely be welcomed by users.
3. Face unlock
Similar to what you find on some notebooks, you can now use the front-facing camera to unlock the phone. The device will use face recognition to see if it’s really a registered user trying to get access–an alternative to keying in a passcode. It’s nice to have, but we doubt it will make the phone more secure than it already is. The demonstration of this feature didn’t go that well during the Samsung-Google event, but we’ll be sure to try it out when we get the Galaxy Nexus.
4. Voice typing
Android has had voice-recognition capabilities for some time now, allowing you to search by talking to the phone. This feature is now expanded so you can type by talking. If this works well, it will be a boon for those who have their hands full and need to send an email or text message urgently. We are a little concerned that Asian accents may be hard for the OS to recognize, but that’s something we’ll find out later after trying it
5. People app
Contacts have been improved with the People app, which integrates contact details with social networks in a new interface. The first thing you’ll see is the “Me” profile which lets you add your own details, right at the top of the list. Once you key in your own credentials, relevant details from services such as Facebook and Google+ will appear for all your friends.
Here you can press the power button and volume key to take screen shots. You can view, edit and share the screen shots in Gallery.

In addition to this Android4.0 camera has real-time face recognition, and select the focus point fingers.
