Do I need to make an appointment to have my iPhone screen fixed at an Apple store? Or can I just walk in and ask for a fix?

An appointment works better

You can do both. I'm pretty sure you can make in appointment online if you are worried about a wait and don't want to call and talk to someone.

Appointment would be better. If it's busy then you would have to wait for a genius to be available if you don't make an appointment
