One of our replacement Note 7s had a couple of glitches, so we took it to Sprint for repair yesterday. The Sprint tech couldn't fix the glitch and called Samsung tech support. After the conversation with Samsung, the Sprint tech still had trouble getting the phone to work. He found out Samsung disabled gmail access on the phone so it wouldn't work anymore. Then we found out today that Samsung plans to do this to all Note 7s in 2-3 weeks. Just a heads up in case you aren't aware of this so that you can be prepared.
