Place a suction cup on the screen near the bottom edge of the phone.

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

Pull the suction cup upwards and insert an opening pick in the gap between the display glass and the frame.

Slide the opening pick to the bottom left corner to cut through the bottom adhesive.

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