Once the screen is warm to the touch, apply a suction cup near the top edge of the phone right under the earpiece speaker.

If the phone's screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

Only insert the tip of the opening pick under the screen (about 1/8 of an inch) to prevent damage to components underneath, such as the front facing camera and the earpiece speaker.

Pull up the suction cup, and insert the tip of an opening pick under the display where the earpiece speaker is located.

Slide the opening pick to the top right corner of the phone to cut the adhesive.
