Hi @Jemz, let me see if I can help out here! 

As there is no setting available in the phone that is able to improve the touch response in the display, I suggest that you try to repair the software on your phone using a computer and Xperia Companion. Keep in mind though that a software repair will erase all user data, so remember to do a backup of your data before the repair.

If none of these measures manages to improve the functionality of the touch screen, I would advise that you get in contact with your local support team in order to have your phone sent to an authorized repair center. If you have any questions regarding the service such as routines, warranty and consumer laws, these kind of questions are best answered by your local support team as well.

Let me know how it goes!
