When I receive email on my LG Lucid it seems that 2 email apps get copies. I only have a gmail account. When I delete emails from the gmail app, I often have to delete the same messages again from the other email app. There are 2 notification icons as well. But this other app doesn't get all emails, just some. This may have something to do with 'conversations', which I don't fully understand. Is there a native Android email client that is separate from the gmail client? How do I know which client I'm using? Can I disable the native app?
