IPhone 4 speaker Sounds blown or distorted after screen replacement?

I have an iPhone 4 16 gb gsm AT&T phone that had a broken screen. I purchased a replacement offline. After replacing the broken screen and reassembling the phone the loud speaker on the bottom of the phone sounds distorted and fuzzy almost as if there's some sort of electrical or magnetic interference. The speaker was working fine before replacing the screen. I also purchased a replacement speaker thinking that would fix the problem but it did not.

Any idea as to what could be causing this?

Why are people so mean the internet?

So i asked a question asking if you guys think my mom will get me the galaxy S4 for christmas because she sort of gave me hints. I did not get my hopes up but i wanted to see what people on here thought. I got two answers. Both said i did not need it. And i'll admit i don't need it. I have a iPhone 4s (which is laggy but it works nonetheless).It is obvious i want the phone more than i need it. I mean it is christmas, you usually get things you want a deserve. The other answer said i don't need and don't deserve it and that i'm a spoiled brat and they seemed to be attacking me in a way like i'm an ungrateful daughter. I don't know why that answer was so mean i did not say anything to come out as a spoiled brat. I'm 16 years old, and a good girl. I always listen to my mom and anything she has given me is something i earned. I work hard and study to get good grades.
Why are people so mean if they don't even know you or anything of what is going on?
I know i shouldn't feel too bad but i guess i'm just really sensitive.

Is it possible to not have apps saved in your iTunes library?

I have tonnes of apps on my iPhone, but why do they have to be on my laptop's iTunes library? It's not as if I can use the apps on my laptop!

If I just delete all my apps in iTunes, will they be removed from my phone? Does the app need to even be in my library?

If not, how would I be able to stop iTunes from automatically downloading them and waste all of my memory?
