OTA update for the Galaxy S4 (AT&T version)

There is an OTA update available for the AT&T version of the Galaxy S4 (SGH-i337). The update is ready since September 17th, and requires Wi-Fi to download, as the file size is 121 MB – 977 MB, depending on the current Android version of the device.

AT&T has detailed the list of changes that the new version will bring to the users, mainly focused in connectivity improvement, security patches and some updates of Google apps. It’s also recommended to make a backup of the data before the update, although it shouldn’t affect the data stored in the device.

In any case, Samsung Kies can be used to backup as well as to restore the phone.

How to install the update

In order to download the file, we have to navigate through the “Settings” menu until we find the option “About device”. There, we need to tab on “Software update” and “Check for updates”.

We should accept the question regarding if we actually want perform the update before the download starts. Then we can choose the Wi-Fi network we want to use to download the file and we will be notified when the software is ready to install.


It will take several minutes to install and the device will automatically restart when the software is completely installed. We can check the new version of the software by taping on the “About device” menu from the Settings. We should see the new information after the software update:

Android version: 4.4.2
Baseband version: I337UCUFNI1
Kernel version: 3.4.0-2539008
Build number: KOT49H.I337UCUFNI1

The changes are not very evident, but as it is an OTA update, it doesn’t require much effort to have the new version ready and running. And since it is generally a good idea to have installed the latest version of the software available, there is no need to wait any longer. You just have to be sure to use a Wi-Fi connection before attempting to download the file.
