Hi Jessica,
How far was the fall to the ground? It sounds like the screen might have gotten damaged, I don't think a factory reset will fix this issue but I might be wrong as well, technology can be insane sometimes, for a hard reset you don't normally have to remove the sim card, but to be safe remove it, I have heard of stories where people lost all their contacts that was saved on the sim when they did a factory reset.
Let me know if you came right
Ewald
