Finally got it on mine, some people have had the ota update by restarting Google services or the tablet itself.
Was confused by the split notification thing at first but glad Google have added quick settings in as default... Bout time!
Any other cool new features to look out for?
Edit: Warning to all, the update breaks both dice and mx player :-(
Edit 2: mobo player seems to work still. Has a lovely overlay feature aswell, definitely worth checking out! Couldn't get BS player to work
