I'm having trouble with a Samsung WEP 850. The 850 supports HSP, and HFP. The HFP functions aren't working: it doesn't disconnect when a call ends, and the redial doesn't work either.

I guess it's using the HSP profile--it's also got a headset icon when connected, and it's referred to as a headset on the dialpad. Is there any way to get the HFP features to work?
