  • Apply a suction cup as close to the heated edge as possible.

  • Carefully slide the tip of the opening pick down and up the side of the phone, making sure not to cut deeper than 1/16" (1.5 mm).

  • As you run the pick along the side, you will feel the tip of the pick press against the edge of the OLED panel. That is as far as the pick should go without damaging the panel.

  • Once you have separated the adhesive, leave an opening pick in the side to keep the adhesive from resealing.
