I'm a noob to S3 (2 weeks). I've been an iphone user for the past 4 years. I basically got the S3 because of the bigger screen. Now I'm beginning to regret switching to an android. I've connected the S3 to my pop3 mail server. I've also stated that the emails are to remain on the server (via my apple computer I stated "after 30 days" it can be removed; via the S3, I stated "delete from server NEVER). Mail worked fine for about a week. Then I noticed that an email that was in my S3's inbox (there for about a week and already read) DISAPPEARED. I searched for it everywhere (different folders, outbox, deleted email, etc). I could not find it. Moved on in life. Then, on another day, it happened again! An email that was already read but kept in my inbox disappeared. Searched again, but could not find it. Nothing unusual is happening on my Apple, just the S3. On my iphone, I was able to leave emails (after read) in my mail application's inbox so that I could have them for reference at a later date. I need to be able to do this on the S3. Can someone please help. I've also searched other forums and an app called K-9 was suggested. I've set up that app but don't like using it as it is not "pleasing" to look at, nor can I have it list my emails by SENDER. It currently lists the emails by SUBJECT line. That's too hard for me to decipher when on the fly. Thank you in advance.
