Any camera is going to have trouble with this scenario in auto mode:
The subjects are in the shade and back-lit, and the sun is shining directly into the lens through the leaves. (note the lens flare above the ball holder's head).
To properly expose the subjects, you would have to spot meter on the children, and live with the blown out highlights in the background.
Before you condemn the camera, use the available light to your advantage, not as a troublemaker.
Good luck !
