My iphone 6+ has had “Touch Disease” (or I thought it was) since I bought it. Screen Ghosting has been a problem since day 1. I did a DIY fix using some electrical tape on the back of the Touch IC chips to help keep them in place, but this did not fix the problem. Upon further inspection on the interwebs, I found that ALL cases of Touch Disease have the grey bar issue, mine does not, and never has. Is this a problem with the LCD then? It needs to be replaced regardless because of white vertical lines and about a quarter of it being unresponsive, but will this fix my “touch disease” Problem?
Are you getting completely dead no touch issues or is it touching by itself? Touching by itself is usually a bad screen. Edit: Even touch IC fault can cause ghost touching.
You do not always get grey bars with Touch disease, in fact, less than half of the repairs I do have the grey bar. Ghost touch is most likely due to a defective screen or the vertical white lines can be faulty seating of the FPC or hardware as well. You can always try a replacement screen or try reseating the lcd for the white lines and ghost touch. but as for the Touch Disease, you will need the Meson IC removed and either reballed or replaced and a small jumper wire soldered from the M1 pad to its “Via”. I would have also stated that Ghost Touch is not Meson (Touch IC) however, I have had a couple repairs where repeated screen replacements had ghost touch till I reballed and ran M1 Jumper then all screens were okay…
I’m having the same issue you are i got my screen replaced and about a month and a half later the touch doesn’t do anything and occasionally touch things on its own
