I have recently replaced my samsung stratosphere phone. When trying to sign in to my google account from the new phone, I either immediately receive a mesage "your username and password don't match" or I receive it after I have been prompted to re-type the series of letters that are hard to read (slanted, etc.) All this happens after I have successfully signed in to my google account from a computer...same acct., username and password. I have received verification codes and typed them in online successfully. Why can I signin from a computer but not from a mobile device?
