In the following steps you'll be cutting through the adhesive that adheres the rear glass panel to the phone.

For reference, the backside of the panel is shown in the first photo. Note the clearance between the edge of the panel and the fragile ribbon cable beside the fingerprint sensor.

Be careful as you slice and pry to the left side of the fingerprint sensor, as seen from the outside of the phone in the third photo.

Inserting an opening tool more than 3 mm into the phone in this area can damage or tear the fingerprint sensor cable.
