My iphone 5s is being unresponsive on the lower part of the screen?

I can't click on anything below 5 on the pin pad thing. I have the money to have it fixed but, my mom's upset that I don't want to use a newer model so refuses to take me. Is there anything else I can do about it?

That sounds like a hardware problem. There's nothing you can really do other than getting the display replaced.

Could have some one else take you. Its your phone & if you chose to repair than replace, then that's your decision.
