Owners of Samsung Galaxy Note 2 should know that the firmware with build number XXUEMK9 is currently being rolled out to their handsets. Not so long ago, a leaked version of the Android 4.3 OS has also been available for the Galaxy Note 2 handsets, but this software was just in a development stage, so we advise you to replace it with the official firmware. This new Android 4.3 Jelly Bean update will bring several improvements on your phone after the upgrade process. We are referring to a much better RAM management, pre-loaded Samsung Wallet, support for TRIM or Samsung KNOX; and don’t leave aside those updated interesting core User Interface elements which are almost similar to those ones found on Samsung Galaxy S4.
All those who don’t to wait any longer for the OTA update can manually install the Android 4.3 XXUEMK9 firmware on their phone, but not before checking all the risks and preparatory steps that they must follow.
