I have a stock droid 1 and every now and then I will drop a call in my living room. My phone goes from 4 bars before my call, to 0-1 bar while connecting and dropping, and then back to 4 bars after it drops the call. It only happens occasionally in my living room and in the rest of the city i live in the coverage is excellent. It appears to be random and only happens now and then. Any options? I was going to just tough it out until the thunderbolt came out and hope it gets better with a new phone, but who knows when that will happen.
