LG touch sensitive buttons dont work

---

Hello everyone

I have this problem with my phone which is a LG GW620 it has touch sensitive home and back buttons and i recently had to replace the flex cable of this device becouse i broke it. The original flex cable had these foams glued like this:

and the one i bought did not have them:

so now i need your help on what i should do with thease to make the touch sensitive buttons work again becouse without thease foams the buttons dont work.

Sorry for my bad English i hope you will understand what im trying to say here

EDIT: I attached the files with marked areas of touch sensitive buttons and where thease foams are.

Could you mark these foams on photos?
If you mean regular rubbers used to keep things in phone on place - I'd take old ones from old flex and stick them to the new flex.

Yes, what Rebellos said.

The flex circuit board just has the contacts.
The rubber button has a carbon pad on the inside that shorts the contacts.

ok well the flex cable came with those carbonpads so how do i atach the foam to those carbon pads?

Sorry, I don't know what you mean by "foam" vs. the rubber button.
Do you have a more detailed photo?
You should have enough pieces from the old setup.
Can't you figure out how to merge the old and the new?

there is no button on the phone its touch sensitive mayebey it detects heat or something but with the new flex cable it doesnt do that any more.
