Unintended cell phone calls put privacy at risk

I called my brother last week, and we had a 30-minute phone conversation. Over the next four days, and unbeknownst to him, his cell phone called me back five additional times.

Once I could hear him talking work with a coworker. Another time he was talking with our mother. Two other times, it sounded like his wife and young kids were chatting. The most recent time was notable in that he was having a private interaction that I am pretty certain neither he nor his wife meant to be public.

When I called my brother after his last unintended dialing incident, he said that not only had his cell phone called me back several times, but during our original 30-minute phone, he had accidentally opened up another line on his work cell phone. They too had heard everything he told me on his lunch break. Such is the weakness of touchscreen phones: They can't tell the difference between an accidental touch and a purposeful touch.
