The screw is for the waterproof head phone jack it is there because he is using the w10 wireless headphones to keep dirt out must be removed to use the waterproof jack . It is the same jack for waterproof and non waterproof headphones when the small piece of plastic that was removed is screwed on you can plug your non water proof headphones in .
There is only one jack used for waterproof and non waterproof that hole to left is for the screw to hold on the small plastic piece you removed which is tied to the internal waterproof jack . sube

The small plastic screw you remove to attach the waterproof jack in the back of the plastic piece you removed is a place for storing the screw . sube
