Google has officially introduced Android 4.0 today along with Galaxy Nexus. It is also known as Ice Cream Sandwich, and is the much awaited overhaul for Android. Some of the prominent features of this Android release include redesigned user interface, improved multitasking, better notifications, facial recognition (Face Unlock), and ramped up NFC support.
Ice Cream Sandwich also brings Android Beam; an NFC based sharing system, which will help you in sharing apps, videos and other content with other NFC Android devices by simply tapping them.
Few new native Android apps have also been introduced in this release and one of the major ones is the People app with integrated Google Plus.
Camera interface has been redesigned for Android 4.0 and now includes a built-in panorama mode, new photo effects like “silly faces”, “background replacement” and many more.
