How do i turn off the vibration notification while I am on a call? If I am on a phone call, and I get a text or email, the phone vibrates. I want this feature of course while I am NOT on a call, but while on a call people on the other end of the call have described it as a duck being murdered. I have tested it myself and cant disagree with them. It is so annoying and loud. Quite frankly on a work call it is unprofessional.
