iPhone 6s Home Button Replacement

Here's a hot tip. With any home button metal bracket you have you will just need to adjust the concaveness of the metal bracket as shown here:

So the objective is to get a balanced level of the above just enough that it makes the home button feel like original position when you press it. e.g the metal bracket needs to be further away from the home button to give it more space for clicking.

Flex accordingly to make it press properly. Feel free to get the two screws for the metal plate screwed in, just don't overtighten of course.

I bend the middle part of the home button in with my fingers

On every screen replacement I usually just bend them inwards to home button to make it feel like a how the home button should feel closest to when it was never repaired on original screen. With replacement home buttons you will have to do the opposite of that.
