The latest build is named after T399NUVUANK3 and is available for update in the USA only. The firmware is being rolled via OTA, being an official one and hence you are recommended to flash it via OTA. But in case of missing the OTA update or not receiving the notification yet, you can adopt the alternate method i.e. manual update.

Before moving to the update, I must tell you that the latest firmware might bring a number of improvements to your device that might include enhanced emojis, streamlined UI design with white status bar icons, full-screen album art on the lock screen & wireless printing etc. Now let’s take a look on the pre-requirements for the update. Remember, the firmware mentioned in this article is only meant for the T-Mobile Galaxy Light SGH-T399N Smartphone and hence don’t mess it up with the general Galaxy Light.
