I got mine at the Northlake (Atlanta metro) AT&T Corporate store late yesterday afternoon. After confirming twice that they had them via phone call, I got there and was told, yeah, we have them, but they aren't in inventory yet so we can't give them out. I kind of threw a fit since I'd driven through afternoon traffic to actually do the exchange (for interim S7 Edge). Finally a manager stepped in and got it done. Still setting the phone up and don't really have any new opinions yet. I prefer not to use any sort of restore, and actually did a factory reset before beginning configuration. So far so good, but lots to do to get it like I had it.
It's a Black, 64GB, date of 9/9/2016 - made in Korea, but passes IMEI check on Samsung's site.
