So this has happened a few times when my wife and I have been talking on the phone together (we both have the Eris, both 2.1) and one of us will hear a very faint beep followed by silence. When I take the phone away from my face the security pattern screen appears and there's no notification that I had even been talking on the phone a couple seconds previous. This has happened at least twice recently while my wife and I have been on the phone, again when I was talking to my real estate agent (he has an iPhone), and another time while on the phone with my dad who was on a Verizon wireless phone. I don't know what to do or if this can even be fixed. My wife says the same thing happens to her on occasion when she's talking to other people. If anyone could help or give some advice it would be much appreciated.
