Android 4.1 Jelly Bean launched

Android 4.1, Jelly Bean, is the fastest  version of Android until now. Jelly Bean compliments the simplicity and beauty of Android 4.0, it also introduces a new Google search experience on Android. Few best features of the newly launched OS are :
1. Speedier interface,  
2. New Camera app, 
3. Offline voice typing, 
4. Significantly improved notifications,  
5. Siri-like voice search, 
6. Google Now 
and much more.

Few features i've enjoyed using the most so far.

      PROJECT BUTTER

Google used a variety of methods to accomplish this feat, ranging from "sync timing" (ensuring a consistent frame rate across all screen drawing and animation) to triple buffering and touch prediction come together to make everything run just a little bit more nicely, resulting in an overall smoother feel across the user interface.

Jelly Bean runs more smoothly than prior Android versions.

OFFLINE VOICE TYPING

I know its really annoying when you can't dictate anything to your phone without internet or WI-FI connection.

Jelly Bean has made it a thing of the past. Now even if you have a poor internet connection or no connection, voice-to-text tasks are completed locally instead of in the cloud.

As per my experience, offline voice-to-text is slightly less accurate than the cloud-based version.

                   GOOGLE NOW

I am pretty sure that we'll be talking about "Google Now" a lot in the future. Google has made this amazing thing that predicts what you'll need and gets it to you even before you realize that you need it. If we go by theory then it means that your device learns your habits, interests and so on, and then tries to offer up relevant traffic, weather and point of interest info.


I would label it as one of Jelly Bean's best attributes.

         

NOTIFICATIONS                                                                                       
    
 Now the notification bar can do more than ever. It can even expand  to show you your inbox, than just emails. Google Now  also appears in the notifications tray, which means that you can view relevant info just by opening the notifications.             

 

VOICE SEARCH(S-Voice)

S-Voice, the Siri's competitor included on the Samsung Galaxy S III, wasn't a thumbs up.

Anyhow now Google's voice search is powered by Knowledge Graph, which means  that you will now receive what Google deems to be the best answer to your query, followed by some relevant web results. Google's voice search definitely made Siri look a bit terrible.
