I do the thing where you slide the side of your hand across and sometimes it works but usually it just moves my screen. I tried googling it but can't get anything to work.

Hold down the main button at the bottom centre of your screen and at the same time hold the side button that lights up the screen. That works on my S3 so it's possible it could be the same on the s5.1
