A quick-witted American girl managed to save her father and family from being unconscious due to carbon monoxide poisoning by using her father's face to unlock his phone while he was unresponsive to call for help. According to "Phone Arena," the family of the girl, Jeline Barbosa, suffered from carbon monoxide poisoning in their home in Massachusetts. She grabbed her father's phone to request assistance, but the phone was locked, so she quickly used her father's face to unlock it and call emergency services. Although her father was unconscious at that time, the face recognition feature enabled Jeline to unlock her father's phone and seek help. When emergency workers arrived, they found that the carbon monoxide levels inside the home measured over 1000 parts per million, which is considered a potentially lethal level.
