Smashed my iphone and it went crazy?

Ok so i threw my iphone 4s on the ground and it shattered on the front and back but it still turns on, but both cameras won't work and when i try to take a picture its just black, also the sound won't work and whenever i use it the front top right hand corner goes really hot, aswell as the whole steel edge thing and the back top middle if that makes sense. Does anyone know what's going on maybe? Please answer!

You shattered your flash and it trying to work, which is causing the heat, try to use your warranty at an apple store, or wherever you bought it.
