Samsung indicated earlier this week that their Touchwiz UX update would be rolling out today, and they did not disappoint. The new update with a ton of new features began rolling OTA this morning. Normally, UI overlays for Android tend to be "iffy"; however, first initial impressions throughout the industry have been mostly positive. For a reminder of the features this update brings, you can check out our previous coverage, here and here. You could wait for the OTA update, but if you are "antsy", just go to Settings > About Tablet > System Updates to manually install it. Enjoy, and let us know what you guys think in the forums!
