Changed home button, display. Still not working properly!

Hi Hampus,

It sounds to me like the home button is not installed correctly. I have never experienced that the hole on the screen for the home button was too small. Typically the home button slots right into the hole.

First of all, I would take the screen off and 'dry-fit' the button in the screen to ensure that it actually fits - which i suspect it will.

Have you changed the plastic part of the home button? If you have, please make sure that it is actually a iPhone 4 home button and not an iPhone 4S home button.

If you have not changed the plastic part, please make sure that you have placed the home button ribbon cable correctly. On the rear side of the home button, there is a recess that fits the home button ribbon cable outline.

Finally make sure that the ribbon cable is routed correctly and is not snagged or folded anywhere.
