Galaxy S4

21-megabyte update now hitting AT&T-branded handsets, users report smoother performance

Following the T-Mobile update that landed this morning, AT&T's Samsung Galaxy S4 is also getting its first firmware upgrade. The over-the-air package weighs in at just over 21MB, and although there's no changelog provided with the update, GS4 owners over on the Android Central Forums are reporting faster performance and smoother animations on the new software version. If lag fixes are indeed present in this new firmware, then it'd be a welcome change -- in our review of the U.S. Galaxy S4 on Sprint, we noted occasional, frustrating jitteriness in certain animations.

To see if you're ready to update, head to Settings > More > About device > Software update. If you're not seeing anything there, you could try connecting your phone to a PC or Mac and using Samsung's Kies desktop software instead.

AT&T Galaxy S4 owners, be sure to let us know how you're getting on with this latest update down in the comments.
