I have an HTC Thunderbolt and a couple weeks ago one of my coworkers told me he always hears keys pressed during our calls - for the last year! I had no idea because I don't hear them, but people on the other end of the call do. Verizon couldn't figure it out, so they replaced the device. Yesterday on a conference call I was told it did it again -- now I'm wondering if it is something with the phone lines in the New England area?
Factors I've ruled out:
Anybody else have callers report to you that it sounds like you're pressing keys but you don't hear it??
