Hello there, shankate1993.

The following Knowledge Base article offers up some great steps for troubleshooting issues with touchscreen response on your iOS device:

If the screen on your iPhone, iPad, or iPod touch doesn't respond to touch - Apple Support

Fix your touchscreen

Make sure your hands are clean and dry, then try these steps:

1. If you have a case or screen protector on your device, try removing it.
2. Clean the screen with a soft, slightly damp, lint-free cloth.
3. Unplug your device.
4. Restart your device. If you can't restart, reset your device.

If your touchscreen still doesn't respond like it should, contact Apple Support or take your device to an Apple Retail Store or Apple Authorized Service Provider.

Thanks for reaching out to Apple Support Communities.

Cheers,

Pedro.
