If you touch the screen at some specific places, but is not registered by the phone, it meas the sensor can't pick it up. This is possible when there's just some plain dirt at your screen. If it is, try to clean your screen with some IPA (Iso Propyl Alcohol)
Another reason, can be some damage at the inside of the screen, or maybe even a loose connector inside.
To repair such damage, some electronic knowledge and skills are required. If you lack either 1 or both of them, it's best to let a repair-shop check your smartphone.

Try to enter the following characters into the dialler: *#*#7378423#*#*
There you can test a fuctionality of the touch screen. If it's defective you have to change it. (In Sony service center they can do a touch calibration sometimes it helps)
