This morning I "butt dialed" my parents' house 20 times on my walk into work. I imagine they were crazy with rage by the time I realized it. I got to thinking why don't mobile phones have a built in "Butt Dial Defense System?" (BDDS). Sure, I could have turned off the phone or locked the screen before I threw it in my pocket, but that requires some action on my part.
Why can't a phone be programmed to recognize when it's dialing a number accidentally. If the same number is dialed more than 3 times in the span of a minute and there is no direct voice input on the caller's end how about the screen locks with a message saying "Accidental Call Suspected" or something to that effect?
Also, I wonder how much cell phone companies make each year on butt dialed calls. Someone should do a study.
