Iphone 5 black screen! Is is fixable? And if so, where do I go?

So I recently broke my iphone 5 screen which I know is fixable because I already had it cracked 2 months ago… Yeah I know I'm clumsy:-/ this time not only is the screen cracked but it went black with some vertical while lines, however I can still hear people call and text me but I can't see anything.Question is, is it fixable? And if So where do you recommend I should take it to? I live in Los Angeles, CA. Downtown, Culver City, Santa Monica, Koreatown, Hollywood?

Is this normal on an iphone?

We'll I just bough a used iphone 5 and it's kind of scratched up on the sides. We'll anyways about every 3 minutes it loses one percent of battery life and I did the math(although I'm not sure till just lose life every 3 mins) and it said that if it does loses life every 3 minutes it should give me at least 300 minutes of use when fully charged but I think the battery will die much faster later on… So is it normal for the battery to run out this quickly?

P.s. I turned off the unnecessary things like location services, Siri, Bluetooth, auto brightness, etc.
and if it's not normal please tell me how to fix this.
Whoever tells me what I need I will give you as much points as I can

I dropped my iPhone in water and it thinks I'm using headphones?

I accidentally dropped my iPhone 4s in the tub, and it is acting up a tiny bit. It thinks there's headphones in, but that's it, everything else is fine. What do I do? I need audio! I just got it, too! I'm really scared that I won't be able to use it! I already put it in a bag of rice, just in case, but how to get the audio working?

Why can't I view some people's kik profile picture on my iPhone 4?

I don't pay for my internet, so I try to use any available free Wi-Fi. I was logged into my school's Wi-Fi which limits what I can access on my phone. I added new contacts to my kik using my school's Wi-Fi, so it doesn't load their kik picture. My android didn't load kik profile pics either when I added new people, but it always loaded later on when I'm on an all access Wi-Fi. But my iPhone 4 still won't let me load their pictures at all even when I'm on an all access Wi-Fi. I've tried removing them from my contacts, deleting the conversation, and messaging them again, but it still won't let me view their profile picture. I can't see the picture they uploaded for their profile kik pic, just the normal display kik picture which is either a gray silhouette of a man or woman. How do I view their profile pictures without resetting my kik messenger?
