Hello I have some problem with touch screen in past.

some time on low battery random touch appear
and on broken screen phone have same problem.

So I make some application for hot fix this until you change new screen.

app calls "Partial Screen", easy to find on google play
Hope this can be helpful.

Thank you! I had a phantom touch issue on the top right of the screen. When I used the touchscreen test to see what was going on, they were all in a straight line vertically only about a centimeter down the screen, so only one column of the matrix was having the issue. I used the partial screen app as soon as I started seeing it again and it has thus resolved the problem. Because it was in such a small area, I haven't had any issues since working with that area on my screen even with those few areas being disabled. Fantastic work around and thank you again! It was becoming very very annoying!
