I had a ghost touch problem in Motorola G3 3rd. It might have existed earlier, but I realized it after I installed WhatsApp. When I tested video call, the phone went crazy and I had a hard time to get it back in control. After that ghost touches were regular.
I tried all the tips I could find but to no avail. Lastly I tried a sparking gas lighter like this <https://www.amazon.in/Sunlight-Gas-Lighter-Refill-Multicolour/dp/B076BG5CM6>. I kept the sparking head near the screen everywhere and made sparks (the lighter had run out of gas). The screen reacted like I would have touched it, so I knew that some effect happened out of electromagnetic field. That is now a couple of weeks ago and I have not seen one assured instance of a ghost touch.
If the operation keeps my phone in sense even some weeks, it is a good and easy method. I hope this helps others with the problem.
