My google search stopped working and can't scroll

Hmm................... it looks like something within Google Search became corrupted, thus resulting in this error.

First try to erase it's data and cache and see if that helps.

For that you have got to go to settings > apps/applications.

Now you have to search for the Google Search app, which should be inside this menu.

When you've found it, press on it and you should see another menu with the buttons clear data and clear cache.

Just press on those and see if it fixed your problem.
