The Samsung Galaxy S4 was officially introduced in March 2013 and made available for purchase one month later, becoming one of the best-selling smartphones in the world, with 20 million units sold in less than two months after its debut. Well, the smartphone is also available on the US market and AT&T is one of the carriers that have it in its portfolio.

If you are among the AT&T customers who purchased a Samsung Galaxy S4 you might want to hear that a new software update is rolling out for your smartphone. In case you haven’t received the software update message in the notifications area and you are eager to perform the Samsung Galaxy S4 update, you should check for it yourself by heading to Settings > More > About Phone > Software updates, then hit the Check for Updates button and follow the on-screen instructions.

Anyway, you shouldn’t get too excited about the software update for the AT&T Samsung Galaxy S4 as besides the two additional LTE bands that will be enabled and some NFC improvements, there’s nothing else in the firmware package. Of course, there will be some bug fixes too, like fixed issues with rebooting, WiFi compliance, some other minor improvements.

You might also want to know that the new software update for the AT&T Samsung Galaxy S4 has a size of 359 MP, therefore we are recommending you to download the software package while connected to a WiFi hotspot in order not to harm your data plan. After updating your AT&T Samsung Galaxy S4 the Baseband version should change to I337UCUAMF3, while the new Build number will be JDQ39.I337UCUAMF3.

I remind you that the Samsung Galaxy S4 is coming pre-loaded with Android 4.2.2 Jelly Bean customized with Samsung’s proprietary TouchWiz Nature UX interface. There are two international Galaxy S4 variants currently available on the market, one powered by an octo-core Exynost 5 Octa processor (I9500) and another sporting Qualcomm’s quad-core 1.9 GHz Snapdragon 600 CPU (I9505).

Because of the LTE limitations of the Exynos 5 Octa chipset, the Samsung Galaxy S4 I9505 is currently being sold on the North American market, but the AT&T variant is codenamed i337. The smartphone comes with a 5-inch full HD display with Super AMOLED technology, while sporting 2 GB of RAM and 16/32/64 GB of internal storage.

In terms of connectivity, the Samsung Galaxy S4 comes with LTE support, HSPA+, NFC chip, infra red blaster, Blutooth 4.0, and microUSB 2.0, while boasting a rear-facing 13 megapixel camera with autofocus, LED flash, simultaneous HD video and photo recording, image stabilization, HDR, panorama, and 1080p@30fps video recording support.
