The AT&T Samsung Galaxy S4 has received its first software update ever, according to reports from users on our Google+ page, as well as on Android Forums.

The update is a small one, weighing in at only 21.39 MB (as compared to the over 160 MB of the first T-Mobile Samsung Galaxy S4 update), and, while no change log has been published yet, users are reporting performance improvements.

According to a user on our Google+ page, the update has fixed the lag the smartphone used to have, which is confirmed by a user on Android Forums, that says the lag is gone even with animations on. The same user also says that the update seems to have also reduced the AT&T Samsung Galaxy S4’s use of RAM memory, as he has 300MB more free out of the available 2GB.

The improved performance is confirmed by other users, too so if you own the AT&T Samsung Galaxy S4, make sure you get the update. It is available both over-the-air and through the Samsung Kies software.
