Update of 1/17/15 for my Samsung Galaxy Note S3 interferes with syncing Gmail accounts. Get constant message "Sign-in Failed" and the accounts have no updates past 1/17/15. I can get new email alerts and go directly to these, but when I open my email account in phone, there is nothing past the 1/17 date. I have tried reentering my email accounts and still get messages that the server password has changed. What can I do to correct this problem?
