Those strips aren't always accurate...

There are “moisture” strips inside cell phones that show whether your phone has gotten wet or been submerged. Cell phone companies use these like law to void your warranty and deny you repair service. The cell companies claim they are “foolproof,” but in fact, according to the New York Post, they are faulty lots of times. It’s been proven that just by putting a damp cloth next to the phone, you can change the color of the strip! So if you have a problem with your cell phone, and you were told your warranty is void because you got it wet (when you know you really didn’t), here’s what Clark recommends. Find an old cell phone you’re not using anymore, take it back to the store, put a damp cloth near the strip on the battery, and prove to them right there that the strip is not accurate!

However in your case, I'm betting they're spot on.
