Geschiedenis van "The front central button doesen't work"

Hello everyone!

I have a problem with my smartphone.

After I took the mobile with the wet hands, the front central button doesn't work any more. Now the smartphone is useless without this button.

How can I fix this problem?

And which tools and/or components I need?

Thank you very much for your help
