Pocket dialing occurs when a mobile phone's touch pad is pressed by something in a person's pocket or purse, or, if the person happens to sit down a certain way, a part of their anatomy. If the pressed key or screen surface area is programmed to dial or redial a telephone number, a call occurs. This call often goes undetected by the phone's owner. Some phones are more prone to this phenomenon than others.
