GOOGLE NOW

Google Now is a sort of unifying service that takes everything the smartphone knows about the user, and everything the user’s previously wanted to know, and combines it to keep everything on track automatically.

KEYBOARD

The new Jelly Bean keyboard lets you get started by typing a word or two, and then based on what you’ve said, Android makes a few educated guesses on what your next word will be and offers them up as options before you’ve even started typing the next few words.

NOTIFICATIONS

Essentially, actions can now be performed from straight within the drop-down notifications menu. So, if you’ve missed a call, you can text or call back that contact directly from the notification widget. The same holds true for liking or commenting on foursquare check-ins and other social media interactions.

ANDROID BEAM

Android Beam now lets you tap your phone to any other NFC-enabled Android Beam phone to share photos and videos. You can also automatically pair any NFC-capable Bluetooth device, including speakers, headsets, etc., with your phone by simply tapping the phone against the device. “It’s that easy.”

CAMERA

The Jelly Bean camera app now lets users swipe for a quick preview of the last photo taken, but picture review gets even better. Users can continue swiping to see all photos taken, and pinch to shrink the gallery into a film strip UI, allowing users to navigate to the right image quickly.

You can swipe a particular picture from the film strip away to delete it, but in case it was a finger spasm or some other sort of misstep, you can always hit undo to get the image out of the trash can.
