It looks like Samsung is halting the TouchWiz UX update to “assess progress and ensure it’s a positive experience for customers.” Some are speculating that there is a bug with the update that has a negative impact. I hope that Samsung is actually caring what users have to say about the update. Personally it has been a positive experience for me and my Galaxy Tab 10.1 is better for having it.
Let us know in the comments your experience with the TouchWiz UX update!
