Hello. I picked up my S4 in June and so far it's been great. A little while ago it started showing all of the emails in the combined box as unread. All 3797 of them. The individual emails are fine. I even checked them on a computer and it shows the correct number of unread emails. I haven't done anything out of the ordinary with the phone with the exception of sending an email with some pictures earlier today. Any ideas? Thanks.
