Last Friday, a little bit of water spilled onto my iPhone screen and seeped underneath the screen (which I didn't realize at first). I then noticed that there was a darker spot underneath the screen at the edge, and then a few minutes later, it looked like water started covering the entire screen underneath from bottom to top. I turned off the phone and checked all of the sensors, and nothing was red like water had leaked to anything. I turned my phone back on and called Apple. They ran a diagnostic test, and they said that there was no internal damage to the phone. All weekend, I kept it off and in a bag of rice (even though I've heard people say that doesn't work with iPhones). Today, it is still working 100%, but there are darker spots on the screen. It looks like the darker spots are bigger than they were on Friday (I can see everything perfectly...it is just that some areas are darker or lighter than others on the screen). Is this something that can be fixed by changing out the screen, will it go away eventually, or is it permanent damage from the water leaking beneath the screen? All the info I find is about people who dropped their iPhones in water, and that's not the case with mine.
