1. Clean the screen with the included microfiber cloth 

2. Remove the protective film from the sticky side of the screen protector 

3. Place the screen protector on your phone. Make sure the phone's holes and edges align with the screen protector 

4. Once you have checked that the protector is positioned correctly, press down on the screen protector to ensure it adheres properly. If you still have air bubbles under the glass, you can try to push them out towards the edge using a plastic card or the included cloth.
