During a screen replacement job, is there any way to test the home button before I remove it from the original screen if that screen is not working?
You can, but the phone will need to have enough charge to turn on. You can press the home button and feel the haptic feedback from it. Some phones may have it on silent so flip the side switch if needed. I do end up in most cases testing with another screen with the home button installed.
