Home button does not work and turning on take too long

Hello.

I had to replace the screen of my iPhone 7 like three times. The first time everything works fine. However, the screen was cheap, so it failed after two months. Then I replaced it again, but this time the home button did not work. I broke the screen again and this time the home button still does not work but when I turn the phone on, it takes like three minutes. Did I misconnect something inside?..

Any suggestion?

Thank you
