alright so I bought a refurbished droid from ebay seems to be in great condition besides that the ear piece sounds blown but I can get past that. While in a call though I can feel the phone vibrate and all of the sudden the person on the other end of the line can hear me and I can't hear them when I pull the phone away from my ear I notice its back at the home screen and I have to click the phone icon and return to the call and then they can hear me. anyone have this problem before? might there be a hard key like the volume rocker that causes something like this? or maybe the 4 dedicated "hard" keys at the bottom? Im new to this phone and any help would be much appreciated. thanks
