My razr is all of a sudden stuck on speakerhphone. I can press the button on the side and it pops up on the display saying either "Speakerphone On" or "Speakerphone Off" but both ways it is always on speakerphone whether I am am making or recieving a call. I did not do anything in the settings to change the speakerphone settings and I do not know how to fix it.
Just as a wild guess you could reset the phone to the Master Settings. Main Menu, Settings, Initial Setup, Master Reset. It's worth a shot, or maybe it would work to just take the battery out and allow it to reset.
It's fixed now, it fixed itself one day when i decided to use it. I have no idea what made it start or fix itself.
