Applying a 3M Privacy Screen Protector on your smart phone is simple. First ensure your work area is clear and the wash your hands. Place the device on a non slip surface if possible and turn it off. Thoroughly clean the device surface with a lint free cloth, so the screen is free of smudges, dirt and any other debris which could cause bubbles. Using the tab carefully peel the film liner about two inches, but do not touch the adhesive side of the film. Align the film on your device using the pre-cut holes for placement, if the device does not have pre cut holes use the edge and adjacent corners to guide placement. Then use the enclosed applicator with the cloth wrapped around it to apply the film to the display, slowly push it the film down working from one side of the display to the other while pulling back the liner. Once the film is applied, remove the protective pre-film and clean the screen.
