iPhone 6 plus touch not working properly

i have an iphone 6 plus with touch issues, sometimes phone works fine and sometimes touch freezes, sometimes touch ghosting, sometimes touch delay etch. I change two LCD but the same problem, so i decided to take a look at the logic board. I checked the touch FPC connector with a microscope and i see three pins have been corrupted as you can see in the pictures below. Can someone confirm that this is the problem of the phone and it will be solved if i replace the touch FPC? I would appreciate your help.

Do you have gray bars appearing at the top of the screen? If so, your phone suffers from 'touch disease': https://www.youtube.com/watch?v=RPWCiQ65...

In that case, replacing the FPC connector won't work, you'll need to replace the touch controllers. A complete walkthrough for that process can be found in this video: https://www.youtube.com/watch?v=YwcfqBEx.... Alternatively (since this repair is pretty difficult), you could search for a microsolder profressional in your area or return your iPhone to Apple for repair.

However, if you DO NOT see any of the gray bars (as seen in the first video), the problem could be the FPC connector. Although it seems a bit unlikely, since the malfunctioning of the touch screen isn't consistent (if the pins on the FPC would've been broken, some rows or columns would be permanently non functional).

I don't see any grey bars on the phone and when i put my fingers on the FPC and push it a little harder sometimes the issue goes away and works fine, when i remove my fingers from the fpc the issue appears again. So i think that this three pins are important for the phones function

You have right, it is not just the connector. Big touch IC has failed and need replacement
