Palms sweating, pulse racing, heart pounding in your chest. You bring your iPhone to the Apple Store to see if they can figure out why it suddenly stopped working. You know you haven’t dropped it on concrete or exposed it to liquids of any kind, but you’ve heard horror stories of that not even mattering.
The “Genius” pulls out a tool similar to the one a doctor uses to look inside your ear and looks down the barrel of your headphone jack, turns to his iPad diagnostic form and types, “sensor indicates liquid damage.” No!
Unfortunately this scenario sometimes ring true. The ports of iPhones, Galaxy phones and other popular devices have factory installed chemical sensors that change color when exposed to liquids of any kind. These sensors help technicians prove that your phone’s screen didn’t just mysterious go out, but that you dropped it in the toilet and shamelessly tried to pass it off as the device gods frowning upon you.
How Moisture Indicators Work:
The function of the liquid contact indicators (sometimes known as moisture sensors, water contact indicator tape, etc..) is pretty simple. Once a liquid interacts with a sensor, a dye is released within the indicator, changing the color of the sticker, usually to red. Once this is tripped, a manufacturer or repair company may deny coverage as liquid damage usually voids any warranty.
Red Dot Controversy:
But how accurate are these sensors? Scour any technology forum and you will find page after page of complaints of individuals swearing their phone or tablet never touched water, and they might be right. Some have theorized that the indicators can be tripped by being in proximity to sweat or even in high humidity environments. As the age of waterproof devices continues to be established, HZO plans for manufacturers to add its technology, making indicators a thing of the past. In the meantime however, keep that phone safely tucked away.
