Like an idiot, I allowed my Galaxy S4 to be updated Wednesday.
My biggest problem is that I cannot retrieve email from my POP3 account using any of three email programs which worked fine before the update:
1. MailDroid Pro: I get a certificate error with the same settings as before. I cannot fetch mail. I can send mail through the same server.
2. K-9 Mail. Same deal -- can send but not fetch
3. Default Email same.
I don't believe the problem is any server change because MailDroid still works fine from my Galaxy Tablet and I still retrieve email from my Windows machines.
This seems to be at least enough to indict the system update.
Help!!!
