My home button won't work due to water damage
I dropped it into the bathtub but quickly put it in rice to get the water off. My fingerprint scanner works perfectly fine but the home button won't let me unlock my phone or go home, or anything. I have to turn my phone off completely and when I do that it doesn't let me swipe it for it to turn off. Then immediately it turns back on. There's also dark spots on the screen. They don't interfere with what I'm doing though. One is a big oval shape in the middle of my screen. In the top right corner there are just splatters of them and when you tilt your phone away, the whole bottom part is a dark brown.
I don't know how to take my phone apart. I don't even think I have the right screwdrivers and such for it.
