The top edge of the iPad contains the front camera module and two ambient light sensors. These components are easily damaged if an opening pick is inserted too far.

The two ambient light sensors can be hard to see and can be located using a flashlight or by placing the iPad under a bright light.

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.
