Nope. Turned mine in to BB today and back to my Note 4. Reset the N4 to stock, updated to Marshmallow 6.01, reinstalled my apps and just got a new 6440mah extended battery. The device is fast and did not expect it. Have not used beyond VR for the past year and expected a big let down. Nope, seems just as fast in UI, plus LTE and wifi reception are both better than the Note 7. Especially LTE signal.
Another bonus is I prefer the Note 4 display. Looks great and flat, so no side distortion. Still surprised how folks like the Edge. It has twice the side distortion on the display.
Though half the internal storage space of the Note 7, the 256GB card works fine.
Part of my motivation for now is my flights in the next few weeks. I am betting the N7 gets banned beyond just shutting it off. Steps are also apparently in place to essentially kill as many of the devices in the next few months with a stealth update.
I am on Verizon, so not expecting a same time release for the V20. They have Pixels in their eyes right now.
