iphone 8 touch screen not working when home button is plugged in. But when i remover the home buttom cable touch the screen works. the connections look clean. I replace the screen with an original Apple screen. Even tried the original screen that the iPhone have still have same issue I don’t know if it’s on motherboard issue I’m assuming it is

This is one of the common problem shown on the iPhone 8 Plus.I also faced that problem and i solved it.That problem is actually from the pin name display to MAMBA MSYNC CONNECTION pin problem.If you still stuck on that problem that is extremely helpful for you.Before doing you need some knowledge about micro soldering.Do that job carefully.

Plz help me I am stuck in this formate and how do I solve it
