Hey there mrussell2710,
Thanks for contacting the Apple Support Communities today. If having issues with parts of your display not responding to touch, check out the steps listed in the following resource that can help: If the screen isn't working on your iPhone or iPad - Apple Support
If your screen is too sensitive or responds intermittently to touch
1. Restart your iPhone or iPad.
2. Make sure that your screen is clean and free of any debris or water.
3. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.
4. Remove any cases or screen protectors.
If you continue to run into issues after going through the steps above, we'd recommend reaching out to Apple Support for additional information and options at this link here: Get Support - Apple
We hope that's able to help.
Take care!
