Update: Looks like it's nothing to write home about. This update didn't bump up the Android version for me and it's still 6.0.1. Those of you who are not yet on 6.0.1, hopefully this update is going to bring some good news; meaning they might have fixed whatever bugs they had when they tried to release 6.0.1 previously.
The only positive thing I see so far is that it's on the April 2017 security patch level.
The only feature I really want is the ability to hold the home button and close recent apps; not in this update. Someday...
Might be the promised 6.0 update which was pulled the other month probably due to some major bug, let us know if it actually makes it useable also if there is an audio sync adjustments.
I'm going to wait a while b fore I consider updating mine.
