What to do when touch wizard has stopped working on my Samsung Galaxy Grand 2?

My Touch Wizard has stopped working on my Samsung Grand 2. How do I fix it. It lets me make about 3 selections and then locks up.

I turned off motion and gestures.   Also took the battery out and put it back in.  At the moment it seems to be working again.

Go to Settings > my Device > motion and gestures > and turn the settings off. Let us know if that works.
