Hi, Since I replaced a iphone 8 plus screen yesterday. I find now the home button only works when unlocking the phone only. It does not work when trying to close any app or settings screen. Can anyone help resolve this?

Occasionally this is just a software issue. Try powering it off via Settings (as opposed to holding the power button) and then rebooting: Settings-> General-> Shutdown-> Slide to power off. Alternatively, the home button cable in the screen backplate may be poor quality, and I would try replacing that or the screen if you’re able. Worst case you could have damaged the flex cable on the home button itself and that really isn’t repairable.
