Will they take this iPhone 6?

I wanna sell this iPhone 6 to a pawn shop the phone works but the screen is frozen. Will they still take it and give me money?

Unless the pawn shop also repairs phones, probably not.

If the phone does not work as it did the day it come out of the box, they will tell you to go get it repaired and come back. Or they will tell you to get lost.

They sell working items, not trash.

Yes they will, but your return will be lower than you expect to be received.
