Hi my iPhone 6 Plus touch screen doesn’t work I chenged an other touch but it didn’t work too
@Ben is correct, your device likely suffers from Touch Disease. Apple has just announced a (lower cost, not free) replacement program for iPhone 6+ affected by Touch Disease. Of course, they don’t call it that. They will replace your device with a refurbished unit and there are numerous reports that even refurbed 6+ also suffer from Touch Disease. You will lose all of your data if you go this route. If you need to recover your data, then look for a qualified repair shop that does micro-soldering repairs.
You have an iphone 6 plus like me and I had the same problem. I read a lot for this problem and I came to the conclusion that this is a problem with the touch sensors on your iPhone and must be replaced. This is a bit difficult but no matter see this video and i suggest you to try it…https://youtu.be/iKb2itJlxZ0
