If possible, test your screen's functionality before sticking it in place.

Peel and remove the green plastic liner from the adhesive strip to expose the screen-facing adhesive.

Align and set the phone screen on top of the adhesive.

Use your fingers to squeeze around the perimeter of the phone to set the adhesive.

Apply a few books worth of weight on top of the screen for an hour to help the adhesive bond.
