By Kristofer Wouk September 19, 2012 0 28 18 25 AT&T has made a software update available today for the Samsung Galaxy S3. Even though it’s not the one you were probably hoping for, it does add a few handy features to tide you over until the Jelly Bean update rolls out.Advertisement Today’s update weighs in at 82MB and updates the device to version UCALH9. While it doesn’t make major changes, the update does include one very noticeable feature: the addition of a brightness slider to the notification dropdown. Other important but not as apparent upgrades include under-the-hood improvements to VPN and enterprise security. There is a new radio firmware included, version I747UCLH9, but it’s not likely that you’ll notice this unless you were having issues with signal quality before the update. Overall, this is a relatively minor update. We’re not likely to see much until the Jelly Bean update due in October. Of course, some of you who like to tinker are probably already running Jelly Bean on your AT&T Samsung Galaxy S3. To see if the update is available to you yet, check Settings > About phone > Software update. So, AT&T customers, have you got your update yet? 0 28 18 previous postTabletSMS: Text messaging on your tablet via your Android phonenext postCould Android be on a downward track?
