touch scree not working along bottom row

the bottom row of the touch screen on my ifix replacement touch screen does not work properly. when i touch anywhere in the bottom row just above the home button, the row above the bottom row highlites, for instance on the key pad, if i press on the ### space, the cap key highlight, if i press on the space bar the letter key just above the space bar highlight etc. i did all the suggestions including factory rest and now i can even set it up, because in the set up process, the “set up manual” touch command is in the touch screen dead zone. i have taken it apart and reset all the contacts, but still does not work. I think there is something wrong with the screen you set me. It worked ok up until just recently.
