Insert a third opening pick at the bottom left corner.

In the next few steps whilst cutting around the power button and rear camera make sure you only use the tip of the opening pick to avoid cutting the cable, smearing the lens or damaging the camera.

Start to slide the tip of the opening pick from the bottom left corner along the side of the phone to cut the adhesive.

Leave the opening pick in its place at the top left corner to prevent the adhesive from resealing.
