If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener or heat gun for 1–2 minutes to reheat it.

Insert a third opening pick underneath the top left corner of the screen.

When you slice near the front facing camera, insert only the tip of the opening pick (~2–3 mm) to avoid damaging or smearing the camera.

Slide the opening pick to the top right corner of the screen to slice its adhesive.

Leave the opening pick in its place to prevent the adhesive from resealing.
