Q: How can I make my iPhone 6plus touch screen more sensitive?

Hi Devilz_bully,

That does not seem like a good time if the screen is not responding to touch everywhere. For that take a look at the link below to go over some troubleshooting steps like removing a screen protector or simply restarting or restoring your iPhone. If that does not work, then you will need to contact Apple Support for further assistance.
