I have a I phone 6plus I replaced the screen I few months ago because it had the touch disease. It turns on fine but won’t allow me to touch anything on the phone I keep replaying my screen because it’s unresponsive i want to know how to fix it permanently. If someone can help that would be great
Is this a good question?

Touch Disease is a very common failure on the iPhone 6 Plus.
At first, the phone will typically develop intermittent touch control failure. For some phones, a gray/white bar starts appearing at the top of the screen. Twisting and applying pressure in certain spots sometimes allows touch control to work for a short period of time, but eventually, the touch interface ceases to function entirely. This is colloquially known as Touch Disease.
If you are confident that your replacement screen is fully functional and there is no damage to the Digitizer FPC connectors on the logic board, then your phone probably suffers from Touch Disease. This is not a DIY repair.
The current best practice for permanently repairing Touch Disease on the iPhone 6 Plus is to solidify the M1 pad underneath the Meson Touch IC. That pad tends to lift, partially or totally when removing Meson.
Look for a repair shop that can do micro-soldering repairs to properly diagnose your problem.

touch disease is related to the ic chip on the rear of the board. dont keep replacing screens none will fix it...you can put a old sim card under the protective plate covering your lcd cables that will push the board back on to the ic chip ...you could also use a small tip and reheat the solder then push them back to the chip till they cool. there are quite a few videos showing solutions on youtube.

Reflow and adding pressure are temporary solutions.
Real soltuion is to replace the touch ic.
As maybe the case. However temporary is a subjective term. Should the temporary fix last till the owner upgrades then it's not very temporary.
