IPhone 5s cracked screen - 1

I cracked my iPhone 5s November 2013 and I never replaced the screen. Now it gotten worse. The camera and speaker thingy(screen glass thingy) fell off. And a month later, a black straight line appeared. I was wondering what was the black straight line,? Help. I'll change my screen next week so yeah. My friend will change it for me I bought LCD Digitizer screen.

The LCD was probably just damaged. Changing the screen will fix it
