Hi everyone. I've found what's going on!!
Turns out, there is a small strip of black tape in between the glass and frame that keep the digitizer from "touching" itself and activating home button + digitizer randomly.
The fix for this is simple. Just put a thin strip of tape in between the glass and it's flex cables. I suggest Kapton tape since it's adhesive is light and wont damage the flex, as well as being thin, or just carefully transfer the thin tape strip from the original digitizer to the replacement. Be sure not to cover the Digitizer Adhesive of course!
Here are some pictures for you guys!
