Iphone broken or not?

I think some water got into my iphone from the rain today. It was fine when I took it inside and used it to text and all. But then I charged it. And about 5 minutes after charging it, these white lines started to appear on the phone and every second the phone got whiter and whiter (still able to see everything on the screen, but with more and more tint of white). So i turned it off and put it in a bowl of rice, oats, and a beef jerky gel pouch thing. I checked the SIM card slot for that "Water damage indicator" I don't know if i saw it or not, but i didn't see anything pink or red, so I think that means no water damage. What's wrong?

Instagram knows where I (location services are off)?

My location services in my Settings on my iPhone are turned off. Yet, Instagram still knows where I'm? In my search tab, it still has "Philadelphia" stories and my county stories. I don't know how to turn this off and I do not know how it knows where I live because the only location tag I have ever used was when I was in Mexico.

What type of iPhone Case is this and where could I buy it from?

I saw someone who had this iPhone case that had like glitter patches that were soft and if you smooth it out on One Direction, the patches changed to another color. It was these patches that are sometimes on clothing material as well. What is it called and where could I get it from?
