That strip is annoying; there are a lot of things that can make it change that cause no damage whatsoever to the phone. That outside indicator seems more like a scam to me than anything else. Traveling to a humid place caused mine to turn red (I noticed when I went to change my sd card). Because of that one strip, trade-in value is a lot less than it was. I've never needed it repaired, but I'm sure if I did, they would try to claim something about that.

There's a second strip on a lot of phones that's "deeper" inside the phone which indicates water that would have gotten inside the phone.
