Here's some good news for all Samsung Galaxy Note 2 users on AT&T.

Per reports, AT&T has started rolling out a brand new firmware update for the company's Samsung Galaxy Note 2 that is said to bring some new fixes to the device.

Although not a major update, the OTA is bringing some new security updates and bug fixes, and users can update via Kies desktop software as well. Probably the most important thing to arrive with the update is a patch to the infamous Exynos chipset exploit that was discovered in December last year.

"This software package includes a chipset security enhancement, and will update the baseband version to I317UCAMA4. This update is only available for devices that have been upgraded to Android 4.1.2. To verify the updated software version, go to Settings > About device," AT&T states. "If the device shows a previous version, see the instructions below these for information on the Android 4.1.2 update."

As AT&T is referring to the changes as a "chipset security enhancement," so it can be safely assumed that the Exynos exploit fix is probably the major feature of this patch.

As expected, the update is currently pushing out in phases and so the update might be delayed at some places for few users. However, users who do not want to wait for the update notification can get their device flashed with the update manually.

"The previous update of AT&T was released late back in December 2012. The previous update was a bigger one with more exciting features and bug fixes. It also included the multi-window support. This latest update is however, not as exciting as the previous one, but is worth grabbing for users looking for Exynos exploit fix," PC Tablet writes.

The update is also said to add multi-window functionality, apart from software version to Android 4.1.2. The multi-window functionality provides split-screen functionality, which allows the user to use two applications at the same time.

"Although there should be no impacts to settings or data, we recommend that you back up your media files to an SD card, a PC, or using a favorite application (from the Play Store), prior to upgrading the software. For information on backing up and restoring your phone using Samsung Kies," AT&T adds.
