How to use:
1. First, clean the screen with the supplied wet cloth and then wipe the screen with the supplied cloth.
2. Gently pull the plastic away from the cover and avoid rubbing the surface with your fingers.
3. Apply the cover on top of the cleaned screen and push from the center and out to the edges. Should you get air bubbles you can usually push them out with your fingers. Should you get someone who does not give up, they usually disappear when you have used the cellphone for a while.
The entire process takes a maximum of 2-3 minutes.
