Once the screen is warm to the touch, apply a suction handle to the bottom edge of the screen.

If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction handle to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction handle to the screen.

Lift the screen, including its safety frame, with the suction handle to create a small gap between the screen and the phone assembly.

Insert an opening pick into the gap between the screen frame and the phone assembly.

Make sure to insert your opening pick in the right position to avoid separating the screen from its safety frame instead of the phone assembly.

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

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