Camera won't work..at all

I was recently given this tablet from a friend. I mainly wanted to use a tablet to play games… Some of my games crashed so I took them off the tablet and play them on my Android Samsung phone and also my desk top Mac.. Other games I play on this device work fine ..but load slow…

My other question is about the Camera… When I would click on the Camerea icon the screen says Camera error

----------------------

Can't connect to the camera

is there an easy fix...
