Find a low-dust workspace. Anywhere indoors with calm air is a good start. 2. Wash your hands. Dry them with a clean towel. Shake off any excessive lint. 3. Clean the screen. Wipe it with a mild solvent like eyeglass cleaner or a damp soapy rag. Then rub it dry with a soft cloth and remove as much lint as possible with a blower or by wiping lightly with a lint-free cloth. 4. Check the placement of the screen protector. Carefully remove it from its box or packaging. Before you lift its backing, position the screen protector over the screen to see how much margin to leave on each side. 5. Install. Peel back the screen protector's backing from one end (leaving it on the other allows more control by holding that end). Align it with the correct edge of the screen, leaving the margin you determined previously and watching how the alignment of the sides perpendicular to it will fall. Then peel off the entire backing and smooth down the protector. 6. Remove air bubbles. Wipe the air bubbles toward the edges with a smooth implement like a credit card. Don't do this forcefully unless the screen protector has a surface protector to peel off after installation: the air will eventually diffuse out and too much force could scratch the brand-new protector. 7. Finished! Use your love phone without fear.
