The difference between Android Jelly Bean and Ice Cream Sandwich is not too significant. But of course you’ll found some improvement in Android 4.1 Jelly bean as it is the new update of Android 4.0 Ice cream sandwich.
While Android 4.1.1 Jelly Bean isn’t the latest version of Android, but it does offer significant improvements over Android 4.0 Ice Cream Sandwich.
Here are some improvements introduced in Android 4.1 Jelly Bean.
Prior to Jelly Bean, Android lacks smoothness and responsiveness when compared with iPhone and high-end Windows Phone to some extent. Project Butter is the Google’s effort to get rid of such performance issues and make Jelly Bean more faster and smoother. Jelly Bean’s “Project Butter” helps in improving graphics rendering at 60 frames per second, for which it extends vsync timing across all drawing and animation within the Android Framework.
Jelly Bean also adds triple buffering in the graphics pipeline, with which it reduces touch latency. Interesting fact is that it predicts your next touch at the time of the screen refresh, which ensures more reactive and uniform touch response and while, you touch after periods of inactivity, it boosts CPU input to max at the next touch event to ensure minimal or no latency.
Smarter Predictive Keyboard and Offline Text-To-Speech
Jelly Bean’s keyboard looks quite similar to the Ice Cream Sandwich, but the dictionaries are now more accurate and relevant. It learn your typing from time to time and show the words before you type them using bigram prediction and correction. The version has also an enhanced offline text-to-speech feature, making voice typing on Android more better, without a data connection. The stock keyboard is available in over 20 languages with a dedicated selection key that help in switching languages quickly.
Google has made a great improvement to Customizable home screen in Android 4.1 Jelly Bean. While with Android 4.0 ICS, you have to struggle with your widget to fit in the screen, but with Android 4.1 Jelly Bean, widgets are easier to re-size to fit your home screen. The screen automatically adopts placement and re-sizing widgets according to your finger’s movement. And widgets can be removed very easily through edit mode or by swiping on and off the home screen.
The notification bar has also been enhanced in the Jelly Bean. This is a bar at the top of the screen which can be pulled down to display the notifications like missed calls and email alerts. In Jelly Bean, an expanded view is available for these notifications while in Ice Cream Sandwich, there is only a small fixed view, showing less information.
Now in Jelly bean, you can save the map to a storage device and access it offline. To do that, you need to select ‘make available offline’ and select a rectangular area on the map that you want to cache in memory.
Jelly Bean is the faster and smoother version of Ice Cream Sandwich and it surely comes as a big competitor to iPhone and Windows phones. Jelly Bean comes with plenty of new features that makes it a clear winner over Ice Cream Sandwich.
For those who are using Samsung galaxy note, S2 and S3, you can use OTA (Over-The-Air) or KIES to update your phone to the Android 4.1 Jelly bean. Make sure your WIFI is on and your battery is at least 50%. If you can’t update via KIES or OTA, then you’ll need to download the firmware and use ODIN to flash.
