I have no idea why this is happening but after a recent software update my phone continues to vibrate after I pick up an incoming call. Does anyone know where I can set the "vibrate on incoming call" to off AND/OR just fix this annoying issue? It just seems like whatever is sensing the phone getting picked up isn't working...so while I'm talking there's this awful vibrate happening throughout the call. Once I hang up, it stops. Thanks for any and all help!
