"home button not working after charger port replaced."に関する回答The device charge port contains two vertical gold pins that are responsible for transferring the signal of the home button. Sometimes these pins are defective. They either don't make a solid connection with the home button bracket on the screen or their connections to the charge port flex cable are damaged. The only fix for that is to RMA the charge port you originally purchased and have it exchanged for another one. Install the next charge port and your home button should work again just fine. Hope this helps. If a new charge port does not solve your problem then your home button bracket may have been damaged during the repair. If so, you'll have to get another one to replace it with. I don't find this option very likely. It's possible, but not likely. You're much more likely to have a defective charge port. If you've replaced both parts and it still doesn't work then you may have a motherboard issue. You may have to just stick with the assistive touch soft key on your screen.
