I have been using my Acer spin 3 sp315-51 i7 for about 2 years and never had any problem with it. But last week, it started giving ghost touches on my screen. I am doing my college work and suddenly on the right side on the screen multiple touches starts to appear in the vertical position and it messes up everything on show. When I close the lid and open it again, it disappears and reappears after 10 minutes or so. Besides disabling the touch screen, what can I do to fix this problem?
