Can sprint replace my iphone or what?

I cracked my iphone 6 last month, and and dropped it here and there a couple times since then it is kinda badly cracked, so last night it was working normal, then i picked up off my bed and i see these colored lines going through it, i know its messed up from here, then these black spots appeared, so i start getting mad and so i pulled up the screen a bit cause im thinking its trash now, i may have damaged it more, but i soon realized maybe this can get fixed. Can it? And im on a contract from sprint that still has over a year left, i didnt have phone insurance, is there anything they can do, will they send me a new phone for a renewed contract or what.
