When placing a phone call, my wife's new Galaxy S-lll sometimes connects to (calls) a contact (one that's among the phone's listed contacts) that is NOT the contact she touched to call ... ie. a wrong number is called. I've removed and then re-entered the contacts involved but that did not help. Has happened several times on several numbers, but not always on those specific numbers. Often those numbers work fine, with no Wrong Number connection. What's happening and what can be done about it? Thank you.
