The AT&T Samsung Galaxy S4 is now being updated with the official Android 4.4.2 KitKat update OTA. Most users expected this device to receive the final KitKat 4.4.4 build, but it seems like that might not happen any time soon.

This update is being released over the air and the file size should be somewhere around 121 MB and 977 MB. The difference comes from the fact that there are users running Android 4.4 and they would need to install the first Android 4.4.2 firmware along with this latest Android 4.4.2 build. All the 4.4.2 KitKat build are grouped into a single download hence the 977 MB in file size.

The Android 4.4.2 KitKat 1337UCUFNB1 firmware update is available via OTA and it is being rolled out in phases and it should be installed on all AT&T Galaxy S4 phones by the end of this month. The official changelog of this new Android 4.4.2 build for Galaxy S4 AT&T states that it adds security patches, updated Google applications and connectivity tweaks, so that all the receiving calls will be of higher quality and the text messages will arrive faster.

After the update notification arrives on your AT&T Galaxy S4 you should simply confirm the download process and then the device will take care of the rest of the installation automatically. Note that the update is being released to various regions across the US, but it should hit all the phones by the end of this month. So, you shouldn't panic in case the Android 4.4.2 I337UCUFNB1 OTA Update notification hasn't been sent your way until now.

If the new update fails to arrive until next week and your AT&T Galaxy S4 device is running stock Android 4.4, then you can go to Settings > About Device> Software Update and use the 'Check for Updates' button in order to verify if there are any files available for you to download. Confirm the installation and let the phone take care of the rest of the process if there are any new Android 4.4.2 KitKat files available for download. Tell us in comments how is this new official firmware working with your AT&T Galaxy S4 phone and if you've found any extra features that aren't listed in the official changelog.
