I got my Inc about 2 months ago and at first I thought this was just a fluke, but it's happening all the time. Basically, if my phone is sitting flat on my desk and I get a call, the phone will ring for about a second before going silent. It still vibrates and still wants me to answer the call, but the ringtones have stop. I even experienced this today driving in to work. The phone was sitting on my leg when I got a call. Same problem. Rang for a second and then silent. If I am holding it or it's in my pocket, it seems to ring without any problems. Has anyone experienced this or has any ideas what it may be? That "silent ring on pickup" or whatever option in the settings is not selected and I don't believe I have any sort of app installed that controls the volume of the phone.
