Inside every iPhone is a moisture sensor: a small dot of liquid-sensitive material that turns bright pink if the iPhone’s insides have been exposed to being submerged. It’s the method Apple uses to protect itself from having to replace iPhones that clumsy customers have dropped in a puddle, their beer or a toilet.
Now a California woman is suing Apple over these moisture sensors, claiming that two separate iPhones died and were then denied replacement by Apple because the moisture sensors had been triggered. The woman, Charlene Gallon of San Francisco, claims otherwise.
