When I try to sync my email inbox accounts with my Samsung Stratosphere via Verizon I am getting an error code 80304 stating that 'log on credentials does not match my provider' Both Yahoo and Gmail give me same error code. When I try to log in via Menu/Settings/Account Settings/Account Password I get prompted that email accounts are not matched with phone and email providers. I have had phone for about 3 weeks and my email was working and now it has stopped syncing and thus not listing my most recent emails in InBox ??? I have tried to re-boot by removing battery but that did not work. Thanks !
