Hi all. I have a Medion E4002 phone running Android 4.1.1. I've been trying to find how to switch phone calls to speaker, but can't find anything like that under System Settings, so I'm sure I must be missing something that should be obvious. I would like to be able to set the default to Speaker Off, and be quickly able to switch to Speaker On either before or during a call at my option. Shortcuts would be really good, rather than digging into the menus every time, even if I knew where to dig into, which at the moment I don't. Any suggestions most welcome.
