Hey guys, I got my new iPhone 7 Plus today and I noticed this problem when I first click the home button but then found if I pushed hard on the bottom area of my phone the screen would click, If you want to fix this all you need to do is tighten the 2 screws at the bottom of your phone near the lighting port, since tightening them I have tried everything to try trigger the clicking again and nothing is causing the clicking anymore, Hope this helped everyone out
