The international Samsung Galaxy S3 seems to have received another OTA upgrade. This one makes substantial changes to the user experience.

More specifically, we now have slider controls for device brightness, better options for audio, more toggles in the power menu, fixes for AccuWeather, and a lot more that users are noticing over at AndroidForums.com.

Keep in mind that this is only confirmed to be going out to the unbranded international versions of the device. Carrier specific devices will have to wait until adaptation and testing is done.

There is one report of T-Mobile UK devices getting the upgrade but don’t take my word for it. You’re looking for a 72MB build with build number I9300XXLFB. Go ahead and check for the upgrade in your phone’s settings menu. [Thanks Shaz!]
