Lay the iPad screen side up.

Use the flat end of a spudger to pry up the rear camera.

If it's difficult to pry the camera up, apply a heated iOpener, wait two minutes, and try again.

Don't use isopropyl alcohol to weaken the adhesive or you'll damage the rear camera.

Remove the rear camera.

During reassembly, you can reuse the adhesive in the frame if it's still intact and clean.

If the adhesive is damaged or dirty, use tweezers to remove it and use a small piece of Tesa tape to secure the rear camera to the frame.
