There could be a major bug with the TouchWiz UX update for the Samsung Galaxy Tab 10.1 because they have halted it in order to “assess progress and ensure it’s a positive experience for customers.”
There have been some reports that some users are experiencing scrambled graphics which make their Tab completely unusable. There could be other issues, but for now no updates are being pushed. We will let you know more as soon as we find out.
