Slide the opening pick along the left and right edges of the phone to release the midframe clips.

Lift the bottom edge of the plastic midframe up but do not remove the midframe. The midframe is still tethered to the phone by the fragile proximity sensor cable at the top edge.

To reinstall the plastic midframe, align the midframe to the back cover, and squeeze the perimeter of the phone with your fingers to snap the clips back into position.
