Black spot on my iphone 5 screen?

Hi. My iphone's display became really screwed up recently(screen became a bit pixelated, colors warping and display becomes hazy) but now there's this black spot that is slowly growing in size. What is it and can it be fixed?

Why are my tweets splitting themselves?

I have an iPhone, and I use Twitter via the app, but when I don't have 3G/Wi-Fi available I text in my tweets using my shortcode 86444. However, when I use the app again and look back, even tweets that are under 140 characters have been split up into about three tweets, sometimes one of which only contains one word! I don't understand why the tweets do this, is there anything I can do to stop it? It also only happens to some texted tweets, not others. For example:

Desired tweet:
I loved my time at Legoland, will definitely go again!

But what I get is three tweets:
Tweet 1: I loved my time
Tweet 2: at
Tweet 3: Legoland will definitely go again!

Where can I watch cartoons on my iPhone?

I'm looking 4 Clifford's puppy days and doc mcstuffins but I can't find any websites that will let me watch them and don't b sarcastic please I'm doing this for memories plus I'm bored

Was it rude/wrong of me to have said this?

I was sitting in the class and using facebook(I was bored and professor wasn't in the class).So this random dude besides me says to me: "I guess you use your iPhone 5 just for facebook and calling, right? Why did you have to buy such an expensive phone if you only did that?"
Me: Excuse me? Why do you even care? Did you have to pay for it? Anyways, I didn't buy iPhone 5 but I got it as a gift from my parents for getting into this prestigious college.
