I just got the time to install nougat (I know shame on me lol) I'm on AT&T and got version 23. The install went perfectly, the only hiccup was a screen issue on the last restart....a screen door effect with tons of tiny lines everywhere. My screen has been perfect since day one so I knew it was a display driver issue......a restart fixed it. So far I'm liking it way more than I expected to.... it's a big step up in refinement over mm. The texting app is awesome, makes the stock mm app look pathetic. I haven't got to do much with it yet, no Bluetooth, calls etc but some texting and just checking it has really impressed me so far. Didn't expect that :O :-D ;-)
