Insert a new opening pick in the top right corner and slide along the top edge to separate the adhesive. Make sure to note the following:

Don't insert an opening pick more than 5 mm or you'll damage the display edges.

Don't insert an opening pick more than 3 mm or you'll damage the ambient light sensors.

Don't insert an opening pick more than 2 mm or you'll damage the front camera module.

Leave the pick in the top left corner to prevent the adhesive from re-sealing.
