My wifes Bionic has begun to act up recently. When it recieves an incomming phone call, you can see the call info on the screen and even answer it if you notice it. However i will not play the ring tone or vibrate. The volume is full and there is a ring tone set. I have done multiple battery pulls to no avail. I have even pulled the battery, sim and sd, waited about 10 minutes and put it back together with no results. A factory data reset will be my LAST RESORT, however I would like to avoid that. Any help would be greatly appreciated. Thanks in advance.
