If you own an Android phone or tablet, updating it’s operating system is of utmost importance as it will bring many new features and functionalities.
All the companies selling Android devices have more or less announced their plans for the Android 4.1 Jelly Bean update. This update will bring exciting features and improvements including speed enhancements, improved search features, and a small voice recognition engine that fits in the device itself, without the need for installing external support. This means for voice recognition and support, the Android device won’t require an active internet connection.
Here is what these companies plan to do:

The Korean giant is planning to upgrade its Galaxy S3, Galaxy S2 and Galaxy Note to Android Jelly Bean. However, Samsung has not specified how much time it will take to bring these phones to the latest version.

Other phones in the Samsung line up like the Galaxy R, Galaxy S Plus and S Advance have the desired specification to support Android 4.1. However, Samsung has not announced any plans to upgrade them. These devices have not even been updated to Android 4.0.
