I've had my Note 4 since Day One and have been very happy. Until now. A few days ago, the default e-mail app (which I use with an Exchange account) became painfully slow. New mail is indicated, but the in-box won't refresh for a long time. Like maybe 30 seconds or so. I don't think Exchange is the problem, because I tried the Cloud Magic app, and it works perfectly. (But I don't like Cloud Magic for other reasons.) Is anyone else having this problem, or does anyone have any suggestions?
