WILL MY IPHONE 5 GET REPLACED BY APPLE?

I don't have apple care and I got my iphone 5 as a gift. It has marks on it but not on the actual screen. Yesterday I saw a black spot on my iphone and overnight it started to grow and now it's HUGE. It also has a yellow, blue, and purple glow around the black spot. I heard its a dead pixel but will Apple replace it right away? I'm so sad. I didn't do ANYTHING to it. It was perfectly fine before.

It's a 5. The 5 came out in 2012. The Apple warranty has expired. Nope. If you didn't do anything why does it have marks on it? It's been dropped before because the LCD screen is now dying. It needs a new screen. Here's how to do it yourself when you order the parts. Best luck.
