The Sprint and T-Mobile variant of the Galaxy S4 got there updates, now it is AT&T’s turn. An update has begun to roll out to you AT&T Galaxy S4 users out there, but do not expect anything major. So far, people are reporting a performance enhancement and that is about it. My source article from Droid-Life mentions that he thinks the camera has improved, but it could just be all a placebo effect. The build number is I337UCUAMDL, and is a tiny 21 MB in size. So check in your system settings, you might already have it in there waiting for you. Let us know if you got it.
