First take out the screen film to make sure that its size is the same with that of the screen. And after confirmation, you will see there are stickers marked 1 and 2 on the protective film. First fold the sticker marked 2 as the figure below. Then turn over the screen film. The side marked 1 should be adhered to the screen and it is ok to first uncover it a little bit.
