I'm impressed with the update, though it is strange getting used to how things are very different. I use full screen all the time, and contemplated downgrading when I thought it was missing! But now I've found the right settings, I'm slowly getting used to swiping up the lower screen for the 3 buttons.
I like how the screen is now better utilised for the design of the Note, moving things to the bottom, and more accessible.
I haven't found a way of changing how the recents screen displays yet. I like to see a list of cards like before, not a fan of pages in the slightest. You've no idea how far to scroll to quickly find the app you want, and so annoyingly whizz past it!
Another thing is the lock screen, entering the pin now takes more input to unlock the phone. Making it slower when the phone is docked and I can't access the finger print sensor.
All minor things, rest is excellent.
