There are many possible reasons to have phantom touches on screen let me explain
Capacitance has little to do with conductivity and virtually no electrons actually cross the
capacitance gap (think insulator). It is a measure of a change in the electromagnetic field around
the anode and cathode...causing a change in the difference of pressure between negative and
positive electrons on those competing surfaces separated by an insulator (or ambient charge).
By bringing something capable of either holding a static charge, conducting electricity or otherwise
affecting the measured capacitance (electromagnetic field) near it, the capacitance changes and this
is how it determines where the screen is being touched. It doesn't have to actually contact (or
conduct) which is why you can place a thin cloth or piece of paper over the screen and still activate
Don't believe me? Try it. Put a piece of printer paper over the screen and then try to select an app.
Don't be too shocked when it loads. Another test , even more revealing to prove it... Put your phone
in a zip-lock bag (the plastic bag doesn't conduct electricity), and zip it closed. Then watch in
amazement as the phone's touch screen works perfectly inside the bag. If this weren't true, then
screen protectors wouldn't work unless they conducted electricity.
Moisture, grease, dirt...even dust changes the capacitance and can create an unstable reading such
that it can detect "ghost" touches, or real touches can be distorted fooling the digitizer into thinking
it has more than one press going on (this is a multi-touch screen digitizer), or that the actual press
is somewhere else on the screen.
Voltage fluctuations and "dirty power" such as produced by lower quality wall adapters can also
cause similar results. There are plenty of threads on the subject.
In your case, it was obviously hardware, but just because you identified and resolved your issues
regarding hardware, doesn't mean anyone else who offers an alternative potential cause is a "weirdo". By making blanket statements like that one, you effectively rule out all but your own
hypothesis, and then you make yourself look like the "know-it-all weirdo".
