Official Android 4.4.2 has been making its way to various variants of the popular Samsung Galaxy S 4 over the past month. Now, the update has arrived for the AT&T Samsung Galaxy S 4, coming in the form of build I337UCUFNB1.
Aside from bumping up the Android OS version to 4.4.2, build NB1 also brings Galaxy Gear compatibility, drag-and-drop to uninstall / disable apps, and calling improvements. Furthermore, the update also brings improvements to various of the included apps such as the phone dialer, the stock camera, and the gallery app.
The OTA is making its way to consumer devices via a staged OTA rollout. As such, your device may not initially receive the OTA. Thankfully, XDA Senior Member Maribou was kind enough to mirror the OTA, while Forum Member lordnihilusmd provided instructions on how to side-load the update.
To learn more about the MK2 (4.3) and NB1 (4.4.2) updates for the AT&T variant of the Galaxy S 4, head over to guut13′s information thread.
Please note that root is not yet available for the new update. Furthermore, SuperSU survival mode is not able to regain root during the upgrade. As such, you may wish to block the update until a suitable root option is achieved. Thankfully guut13′s thread linked above also shows you how to block the OTA if you desire.
