First, give your phone screen a good clean. Remove any dust, dirt, oily residue, fingerprints etc. Once you are happy with this, you can begin to apply. Peel back the top of the first layer (use the tab to help you) and line up the screen protector with your device screen.
These screen protectors are very easy to apply, simply remove the first layer then line up the screen protector with your devices screen, push any air bubbles out with a credit or debit card then remove the top layer and that's it your done!
