AT&T Samsung Galaxy Note 2 gets new Android 4.1.2 UCAMC3 firmware OTA Update, Adds New Radio and New Kernel

The AT&T variant of the Samsung Galaxy Note 2 device has received a new OTA Update today and, you can apply it only via Wi-Fi. Check your device’s notification panel or the System Updates menu to see if the new Jelly Bean update has been pushed out for your smartphone.

Android 4.1.2 Jelly Bean measures only 69MB and it is available via Wi-Fi as an Over-the-air update. It doesn’t bring too many changes, but only a new kernel and radio. It firmware build has the version number UCAMC3 and it currently doesn’t feature any change logs. However, it has been confirmed by multiple users that new kernel and radio has been included in the package.

The changes added with this OTA Update should improve the WiFi connections and the overall performance of your device. So, turn on the Wi-Fi connection on your AT&T Galaxy Note 2 and check the System Updates section to see if the UCAMC3 Jelly Bean 4.1.2 firmware has been made available. If you check that menu but, there is no OTA Update file available, then you will have to wait until AT&T decides to release it for your smartphone.

Numerous users thought that the new update will upgrade their devices to the latest Android 4.2.2 Jelly Bean OS, but  it wasn’t the case and, for the moment, they had to settle for a new version of Android 4.1.2 JB. In the coming weeks ( maybe months?),  AT&T is expected to launch the Jelly Bean 4.2.2 OTA Update while Google prepares for the I/O event and the launch of Android 4.3 upgrade.

Did your device get the new update version? If it did, then you can tell us in comments if you’ve noticed any improvements after the update has been completed.

If you didn’t get the update, then you should check again after 24 hours, as these files are usually pushed out in stages and not all devices will get it at the same time.

    I just got the update an hour ago.. it doesn’t seem to be different to me from the previous version,, I have a Galaxy Nexus with 4.2.2 version & to be honest I find the Galaxy Nexus better than the Galaxy Note 2.

    I got the update on Saturday for my Galaxy Note 2 (AT&T just pushed it). Now the phone seems to take longer to charge and battery life has dropped dramatically.

    • Mine got way faster. “But” every since unremovable and un-disable-able chrome was pushed with the update, my galaxy froze and browser crashed much too regular than i cared for

      So i rooted it last night, disabled chrome for a whole day and no more hanging or crashing. Tomorrow i will uninstall ‘chrome’.
