yer I got my updat the other day, unfortunately most of the stuff in the updated version is not available to us, ie the YouTube thing iv seen on video's of the updated features, in fact the only things I have found so far is the tap to wake, and the split keyboard in landscape mode.
Thats Because There's 2 Versions Of One UI. There's One UI And One UI Core. One UI Core Is Mostly On Budget Phones. Whilst One UI Is On Flagships. One UI Core Has Less Features Than One UI. Hope This Helps.
