Samsung Galaxy Note 2 N7100 should get the official Android 4.3 Jelly Bean OTA Update by the end of this year. The first test firmware was leaked and it has the version number set to XXUEMJ5. This test firmware packs all the features that are currently present on the Note 3 phone, but now you can also flash it on the Note 2 device.
Android 4.3 XXUEMJ5 firmware is still a pre-release build and it might pack errors or bugs. Samsung is releasing them for testing, so that the final build will be error-free on the day of release. You can flash this leaked ROM using Odin, but it would be best for you to create a NANDROID Backup before installing it.
The N7100 Galaxy Note 2 is the international Exynos CPU variant and the Android 4.3 Jelly Bean brings support for Galaxy Gear, TRIM to improve the phone’s speed, ANT+, Samsung KNOX security, Samsung Wallet, better RAM management, better Display color reproduction, tweaked TouchWiz launcher, brand new Samsung keyboard, new Samsung browser, new Reading Mode and a new firmware for the Camera. Also, some other tweaks and improvements were added for various parts of your smartphone.
The leaked Android 4.3 XXUEMJ5 firmware has been posted on SamMobile’s web site. You’ll find the ROM files there and you can use Odin to flash them.
