Single Yellow circle (top right)

This is the puzzle screen with a yellow ball at the bottom on a surface and the light above.

Solution: Similar to the last yellow one this is done with the light sensor on the phone. When you cover the sensor the screen will go dark and when you uncover the sensor again the ball will jump up in the air. The longer you cover the sensor for the higher the ball will jump. Cover for a few seconds and then uncover to make the ball jump and hit the light at the top.

This completes the puzzle.
