Does anyone know why my touchscreen does not work when someone calls
What troubleshooting have you tried? User troubleshooting consists of restart, reset, restore. Please describe what you have done to try and correct it, so it is not repeated.
I have done all three none seem to work
If you restored the phone as new and did not add content back and it is not functioning correctly, then make an appointment at the Genius Bar of the nearest Apple Store to have the hardware looked at.
You might also want to try this before you see the Genius. If the screen on your iPhone, iPad, or iPod touch doesn't respond to touch - Apple Support
