If you use new adhesive, also remove the old glue on the back cover then grab your new adhesive frame and orient yourself at the opening of the cameras to position. It correctly, peel off the white protective foil and position the adhesive frame on the top edge, and let it slide slowly into the device make sure it sits straight and doesn't protrude beyond the frame press, the adhesive firmly to the edge for this.
