Home button loose after screen replacement
So I replaced the screen and used a third party cheaper screen on my old iPhone 6, but now the home button is a bit loose and I can wiggle it with my finger so to speak, and its making a rattling noise when I touch the home button. The home button works fine except the Touch ID (which is another topic).
I have used this exactly same screen brand 3 times earlier both for this phone and other iPhones, and I have not experienced this kind of problem any of the previous times.
The home button rubber gasket is present and whole, and the metal bracket is screwed on very tightly over the home button. Everything seems to be whole and normal with the home button and its surroundings. I can’t think of anything obvious which should cause this problem?
So any ideas what can cause this problem and how to fix it?
