If you take a look inside the case of your cell phone, you should see a round white sticker placed somewhere on the device.
What is it? This is called a water damage sticker and if your phone is exposed to moisture that makes its way inside the phone, this can be used to completely void your warranty, no matter the reason your phone may stop working.
It does not seem to take much, either; a simple drop of water placed onto this sticker is enough to change its color and void the warranty on your cell phone. For honest consumers who accidentally get a small bit of water on their phone and then 5 or 6 months later, suddenly notice that the phone is having problems, knowing about this sticker is quite useful.
What exactly can you do to stop this little devil from voiding the warranty on your phone should is accidentally get a little damp? The best thing that you can do is to take a piece of satin finished scotch tape and put it over the sticker to keep the color from changing if it gets wet.
If you drop your phone into the toilet or the bathtub, this probably isn't going to be that effective, but if you are just worried about general moisture problems or an accidental quick spill of something on the phone, this should work just fine.
If your phone stops working for some other reason, remove the tape and take it back to the manufacturer for repairs or a replacement.
It is was not exactly a bad idea for these stickers to be put on the inside of phones, though; a lot of phones get returned that are supposedly not water damaged, but are.
At the same time, though, it is bad for the consumer because having such a sticker can completely void the warranty regardless of whether the liquid was the reason the phone stopped working or not. The phone could have just been a defective model and it would make no difference.
Hopefully people will use the information presented here honestly and not try to defraud the phone company into giving them a new item after their phone was irreparably damaged by having a hot cup of coffee spilled onto it or something like that.
For honest consumers just having a bit of bad luck, it is great to know these kinds of things about our electronics just in case. Unfortunately, there are those that will attempt to misuse this information.
