What do I do about this? it dials numbers on the phone, puts on hold, does speaker, and does face time...these have all happened if my face smushes on the phone come on sometimes you have to hold the phone between your shoulder and face....and sometimes my face just touches it. its driving me crazy...is this "proximity issue" or what ? I am new to the iphone and my Husband says his doesn't do that so help...what do i do??? thanks !
