I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

there must some app which you have installed causing the same . you have to check in safe mode.

if issue persisited in safe mode then you have to again visit the SC and asked them to check motherboard.

Hi "Sony Support" I purchased this phone last 2 months. Well the performance is quite well in the beginning but now I'm facing this touch screen issue. You know, I expected a lot in your device, and I even chose Sony Xperia C4 over iphone SE because Samsung and iPhone is too mainstream nowadays. And I see Sony as an excellent choice, but now I'm totally disappointed because this is not the first error that I experienced with your gadgets. I hope that when someone complains about a problem in your device, you go work on it in no time. Sony have so many software problems today. I had problem with my game that freezes on PS3 and I've read that it was also a software problem. My uncle got a problem on his Sony phone, my friend's Sony Xperia Z1 too. They gave it to Sony Support branches and they said that the branch they went to requires more time, sending them to another branches, requiring them to change the parts even though the device is still fresh. PLEASE DO FIX YOUR SOFTWARE PROBLEM/TOUCHSCREEN PROBLEM on Sony Xperia C4 and PLEASE DO FIX ALL SOFTWARE PROBLEM complaints not just on Mobile but on every product you have, Sony. Thank you, and please reply on this message.

My xperia c4 dual(e5333) (5.1 LOLLIPOP) starts to have touch problem after 3 months of purchase. Sometime touch is smooth and sometime change in to ghost mode(lol). Currently I am trying on different combination to check if it fix. I have uninstalled updated webview and it is smooth now. I dont know the exact issue but if the problem be more worse I will send it to the shop where I buy from. From now, I will not buy any sony product.

Finally problem solved by slightly hitting the screen with finger
