I have a Samsung-SM-G900A. I can send and receive emails, however when it comes to deleting the emails when I look at the "Show all folders", I am showing over 200 email somewhere that I can't find. When I tap the trash folder, I show nothing in there. Where can I delete the trash. I've gone to my email account through my provider, nothing there either. Is AT&T hanging on to my emails for some unknown reason?
