Is your white home button SLIGHTLY crooked and has a tiny little greyish speck on the bottom ?
It is off by a fraction. I didn't pull the cable when I swapped it which in hindsight i would do if I did it again. It was kinda sketchy removing the backing and getting it re attached.
The spot at the bottom is actually the "notch" where it sits into the chassis.
I'll try and take a better shot tonight when I have a camera.
