does anyone know the chemical process involved with these? pretty much a white sticker and when it gets wet it turns red.
Moonbear said:I've never seen these stickers on cell phones, and am not sure what it uses if it starts out white. A common moisture indicator used in dessicants is cobalt chloride, which changes from blue to pink as it absorbs water.
I'm rather baffled about why you would need such an indicator on a cell phone. Afterall, if it's sensitive to low moisture, just going out on a humid day is going to react it. If it requires more water exposure, wouldn't it be rather obvious that it's floating in the pool or toilet bowl?
Really? I wish I would have known that a year ago. Although, I suppose that wouldn't prevent water damage after taking a dip in Lake Erie with the phone in my pocket. I'm such an idiot.hxtasy said:Most people clear coat them or put scotch tape over it when they first get a phone so that a little bit of water won't mess up their warranty.
Where are they located? On the inside of the phone somewhere? I've never heard of such a thing. How would that invalidate a warranty if it turns just from normal humidity exposure? But I guess that's a topic for another thread.hxtasy said:They use them for warranty purposes. If the phone breaks and they see that it got wet they will tell you it is your fault and then they won't replace it. You are right Moonbear, whatever it is they are very sensitive to moisture. I don't know if they have got any more advanced lately but the older ones would start to turn just from humidity and body sweat. Most people clear coat them or put scotch tape over it when they first get a phone so that a little bit of water won't mess up their warranty.
If it's like most moisture indicators, yes, it should change back to the original color if dried...if you can get it off the phone safely. Placing it in an oven set to "warm" (whatever the lowest setting is, usually used for keeping food warm rather than cooking it) should suffice to dry it without damaging it.I guess the best bet would be to just make a new sticker or bleach it white. but I was wondering if drying out the substance would do anything.
Um, I don't think that's a very honest approach since it really did get immersed in water, not just reacting from humidity. Don't you think clear coating would void a warranty too, since the tampering would be obvious? It's better to buy the added insurance if you're getting an expensive phone and tend to be hard on them.Oh and i am just wondering, my friend has a very expensive phone he dropped fishing and we were trying to figure it out. i would never spend money on a good phone and if i did i would have clear coated it the first day.

Water detection stickers on cell phones are small adhesive stickers that change color when exposed to water. They are typically placed inside the phone near the battery or SIM card slot and are used to determine if the phone has been exposed to water or other liquids.
Water detection stickers contain a small indicator strip that changes color when it comes in contact with liquid. The strip is made of a material that reacts to water and changes color when it absorbs moisture. This color change is permanent and can indicate that the phone has been exposed to water.
No, water detection stickers cannot be reset. Once the sticker has changed color, it is permanently altered and cannot be reversed. This is why they are used as an accurate way to determine if a phone has been exposed to water.
Water detection stickers are highly accurate and reliable indicators of water damage. They are designed to change color quickly and permanently when exposed to liquid, making them a reliable way to determine if a phone has been damaged by water.
No, not all cell phones have water detection stickers. Some manufacturers choose not to include them, while others may place them in different locations on the phone. It is important to check your specific phone model to see if it has a water detection sticker and where it is located.
