iPhone 11 Pro single touch in games

Hello bensaunders,

Thank you for using Apple Support Communities. Sounds like your son is experiencing issues playing games on his iPhone. It also looks like you’ve done a really great job in troubleshooting this issue. If deleting and reinstalling the affected app didn't help, you might want to consider reaching out to the app developers for assistance. Just in case, this resource can show you how to reach them: How to contact an app developer - Apple Support

However, if this issue is occurring on numerous different apps, we might want to review the following resource for steps you can try with the iPhone: If the screen isn't working on your iPhone or iPad - Apple Support

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.

This resource usually helps with display issues. If you continue to experience display issues, perhaps reaching out to Apple Support would be your next step. They'll most likely need to physically evaluate the device to make sure everything is properly working. You can use this link to reach them: Get Support - Apple Support
