Q: Anyone else having issues with problems hearing phone without speaker

I don't understand your question. What does hearing the phone have to do with the touchscreen?

Hi

It may help to follow the steps here, as appropriate:

• If you can't hear a person on a call or voicemail or if the sound isn't clear on your iPhone - Apple Support

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

If the issues persist, contact Apple Support or make a Genius Bar reservation with a view to having your iPhone checked and, if recommended by Apple, serviced (under warranty, if eligible):
