Hi there! I am having a problem with an ipad 4 that came back for repair after a few weeks claiming it suddenly started ghost touching. After testing it shows that it does generate ghost touches but also on multiple digitizers. Even when i set the digitizer vertical next to the frame so it does not touch the frame at all it keeps doing it. Most of the times it does not even respond on any touch input and just starts flipping out on its own randomly, sometimes more worse then the last time. I have tried 3 digitizers now from different suppliers but they all act the same. Could anybody shed some light as to why this might be happening and if it is fixable? Thanks in advance!
Hi Kevin, First, I am assuming that you tried on the new digitizers without gluing them or pushing them hard in place? (To rule out a creased digitizer cable due to improper installation). Second, did the iPad show any signs of drop when it came back? Any sign of liquid damage? Note: did you try a restore? (Asking if you did, not suggesting that you do). After ruling out the above, I’d use a magnifying glass to look at the touch-screen connectors on the logic board to see if:
- The retaining flaps are missing, broken, displaced;
- The connector is damaged, any pins are broken; you could even test continuity between the connector and logic board;
- Any components around them are missing or broken. Have a look and let us know what you see. We can take it from there.
Sharing what I posted in another topic, because I ran in circles trying to solve ghost touching and my solution ended up being some loose frame screws!! “Ghost touching after digitizer replacement”
