It didn't work for me. I use my S2 as my car stereo and it connects with Bluetooth. I have it restart automatically evey week, so once a week, when it reconnects with Bluetooth after restarting, I have to turn the volume back up and I see that ***** warning. I never saw it with Marshmallow. I deeply regret installing Nougat, for many reasons, and it's taught me a very valuable lesson about Android... never "upgrade" if you're happy with what you have, because you can never go back.
