recently when making or recieving a call with the phone, while bluetooth is connected to a device which I am not using for said call, after a few minutes the call will go seemingly dead, but if I activate the speaker phone function, I can continue the call, but only in speaker phone mode????
I hope once ICS comes out Android catches up on Bluetooth. They have been lagging behind on profiles and functionality when it comes to Bluetooth since Day 1. There are numerous conflicts that other operating systems seem to overcome. My suggestion of deleting and readding is about the only effort without doing a hard reset that probably wouldn't help and would require a lot of effort on your part.
