Shattered my iphone and now it won't turn on?

I got into an argument with my brother and he threw my phone, completely shattering the screen and lifting the camera and top speaker off of the base of the phone. Can this be fixed by a simple screen replacement? Is the LCD just loose, or is it worse?

The sudden shock could've damaged internals. There's no way of knowing until you get the screen replaced, if it doesn't work then more is wrong with it.

I would make your brother replace it since he threw it and maybe you should try not to argue with him so this don't happen

It's worse.
