Continue reassembling your device until you are ready to attach the screen.

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

Peel and remove the green plastic liner from all adhesive strips 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.
