There is a new official test firmware Android 4.3 XXUEMJ5 for the Galaxy Note 2

Yesterday SamMobile got a new test firmware for the Galaxy Note 2, which runs on Android 4.3. Officially, the final update should appear in the next month, so long as the test version is not yet fully perfect, but it might be interesting to review.
 This update provides an updated TouchWiz interface in the latest version. In addition, there exist new features that we already know from the Galaxy S4 and Galaxy Note 3, so that many will have a new incentive to choose it for the next purchase Galaxy Note 2, which is a good update soon. Download the new firmware to test you directly to servers SamMobile .
