Chosen Solution

Hi, I have just replaced the screen of an iPhone 7, i took the old and working home button and put it into the new screen, when i turn it on, the home button does not work. I have also tried with the old screen and the old home button, it was working. How can i solve this? May it be due to a broken flat in the new screen?

It could be, if the home button is still working on the old LCD,you should try a new one OEM (it means better quality) and check the results. Always be careful cause this home button is so sensitive and fragile. Good luck!
