I dropped my iphone & now my screen is just black? - 1

So like a month ago, my iphone 5c fell in the toilet. When I got home, I put it in rice and left it on the charger. After about an hour it turned on. I looked up things online and it said to take the back off of my phone so I did, and my screen had a red line going through the middle. But my phone still worked perfectly fine, besides the fact that the screen had red around it. Now today, when I was walking through the halls my phone fell and when I picked it up my phone was black. It was working this morning before I went to school, so then I just left my phone alone all day at school hoping it would work once I got home and put it in rice and I was getting my notifications, and hearing sounds throughout the day. So right when I got home I dropped it in rice. I put it on the charger and it won't stop vibrating every 2 minutes. Also, I tried holding the home screen button and lock button no luck. What could be wrong? What should I do? & is it fixable?

Why is my comcast internet so slow?
