I replaced the screen assembly and when i reassembled the home button didnt function i took it back apart and checked all the connections and everything was fine. What could it be?? Only thing i can think of is i did snap one of the metal prongs off by mistake on the antenna piece i dont know if that would affect it?
Is this a good question?

It's probably either the home button itself, the connection to the dock connector assembly or a logic board issue. Snapping one of the prongs off on the wi-fi antenna won't affect the home button.
First, try to clear out the dock connector on the bottom of the phone. Sometimes dust/lint can get in there and cause issues. Using compressed air works great.
If you have a multimeter, you can remove the home button assembly and test the button to see if it is working properly. Just measure the resistance (Ohms) when the button is depressed. That will tell you if the home button is working by itself.
My guess would be that it is either the home button's connection to the dock connector assembly or the home button itself is broken.

I just dont get how it broke i didnt even do anything with it when changing the screen assembly?
That's why I would guess it's related to the connection to the dock connector assembly. It's a thin, fragile cable so tweaking it during the repair process is possible.

Scott. I have a similar problem. I replaced the digitizer and lcd, now, the home button does not "click". Are there springs or is the rubber gasket the issue?

That clicking action comes from the ribbon cable assembly that sits under the plastic home button itself. It sounds like either that part is damaged or the button is not seated correctly on top of the ribbon cable assembly. You're best bet would be to take it apart and see if you can get the button to click by itself by just pressing it between your finger and something hard. If you don't get any clicking action, take of the the plastic button from the ribbon cable and see if you can depress the small black circle directly on the ribbon cable itself. You are basically trying to determine if the problem lies within the ribbon cable or if it's not seated correctly in the phone when put together.
The problem is most likely cheap parts from China. Not kidding. The connectors that attach to the home button are not glued down in the screen replacements from China. Their location is not in alignment with the two small contact points in the circuit attached to connector #4. In some cases the button itself does not make contact with the connector plate. I tried everything to get this working...no luck.
