About 3 hours ago I started receiving "unable to sign in" messages for my Yahoo e-mail account on my Samsung Galaxy S5. Until now, it has worked perfectly. I have tried to sign in and just re-type my normal password for my e-mail account, but it won't accept it. Nothing has changed on may e-mail account, the password has not been changed and I can access my e-mail account perfectly normally on my PC.
I'm able to send messages, but cannot receive them. I've tried to type "android" at the start of the IMAP Server address (so that it reads android.imap.yahoo.com) under "incoming settings" as someone has suggested, but when I press "done" it says it is unable to connect the to server.
Any ideas please? I'd be really grateful for your help.
