Is there an app which could emulate back/start/search buttons on nokia lumia?

[WPCentral Question]

I changed touchscreen and immediately my nokia lumia 520 fell on the water. Now touch screen works, but back/start/search buttons don't. I really won't change touchscreen again.

Unfortunately there is no app that is able to emulate those buttons throughout the operating system. New touchscreen may be your only option.
