I have a Droid Bionic. When I receive a call from another cell phone instead of hearing the ring tone assigned to calls (I heard it through the grapevine), the phone chimes as though receiving a text message; however, when I receive a call from a land line phone my phone emits the correct ring tone (I heard it through the grapevine). I have the vibrate feature turned on and the phone vibrates regardless of whether the incoming call is from a land line phone or a cell phone. Any suggestions on how to correct this? Thanks,
