A couple of weeks ago, AT&T began pushing out an update (build number 1337UCUEMJ9) for Samsung’s former flagship smartphone, the Galaxy S4. However, many users reported issues with their handsets once they’d installed to the new firmware which forced the operator to halt the rollout. But now it looks like the upgrade has resumed its rollout process.

According to a post on AT&T’s Galaxy S4 support page, the Android 4.3 upgrade is slowly being distributed to devices located in the U.S., only this time with build number I337UCUEMK2. Now, the update weighs a little more, at roughly 727MB, but other than this minor difference, everything else appears to be the same.

The Galaxy S4 was released back in April, 2013, and packs a 5-inch Super AMOLED display with a resolution of 1080 x 1920, a 1.6GHz quad-core Cortex A15 processor, a PowerVR SGX 544MP3 GPU, 2GB of RAM, 16GB/32GB/64GB of internal storage (expandable up to 64GB via microSD), a 13-megapixel rear-facing camera and a removable 2,600 mAh Li-Ion battery.

The full changelog for the Android 4.3 update can be seen below:

• Android 4.3 OS upgrade
• Samsung Galaxy Gear compatibility
• Drag and drop to uninstall or disable applications
• Call reliability improvements

If you own an AT&T carrier-branded Galaxy S4 and have not yet received the OTA update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the upgrade.
