What phone are you using?
Sanyo Katana lx
Press "Menu>Settings>More>Call Set Up>Auto-Answer - Select/Unselect Speakerphone>Menu(OK)
TRIED THAT BUT SPEAKER ALREADY SET TO OFF....
I think I had the hands free option on... turned it off and it appears to be working.....thanks for your input......
Nope it wasn't the hands free either lol
Hmmm, I can't seem to find any other options. About the only other thing I can think of is to back up your contacts and anything else you wish to save and reset it to factory settings.
