The most common issues faced by the users that are reported in the iPhone 6s users community forum are as follows:

• Too sensitive screen/screen response intermittently (means responses without the user having to input or auto touch)
• Touchscreen in your iPhone does not respond at all
• Ghost Touch / Delayed Touch issue
• Touch doesn’t respond after dropping from hand. (Everything else seems to work fine)

There are some fixes you might try to see if any of them work for your phone. Those are the following listed below:

• Make sure your touch screen protector doesn’t interfere with proper operation.
•  Make sure there’s no internal/external damage (cracking or shattering glass)
• Disconnect your USB-lightning port to check if it works.
• If your phone is above normal temperature wait for it to cool down and then try again.
• Restart your device.
