Here is a perfect fix for you after doing a screen replacement. Loosening the screws is NOT always the best solution as the screws will easily back out and come off over time. The best solution is: Completely take off the home button bracket and physically bend the bracket out wards slightly. Install the bracket back and screw the screws all the way, nice and tight. You may need to do this a few times to get the perfect press of the home button but eventually, you will. Will not take to many tries either. Most of the screens have different thicknesses and can cause the home button to not work sometimes. Do this and it'll fix your device right up with no more issues at all.
