I cracked my screen over my camera?

My brother jumped on my phone and threw it at a wall, (iphone) a few weeks ago, and over the pat few days my phone randomly goes into sort of a negative effect, and flashing lines appear. I have to turn my phone off a couple of times for it to go away, but it just reappears again. Can I get this fixed or should I get a new phone?

Check on Apple's community forum for this problem, but the flashing on the screen wouldn't come from a cracked screen, it would be because the entire phone is physically damaged. Again check online on apple's forums for this problem or get a new phone.

That sucks
