Peel away the clear backing from the camera bezel adhesive strip, exposing the adhesive on one side.

Very carefully line up the rear camera and flash cutouts on inside of the rear glass with the same cutouts on the adhesive strip.

Set the adhesive strip on the rear glass and make sure it does not overlap the edges of the camera or flash cutouts at all.

Use your fingers or the flat edge of a spudger to press the adhesive down so that it bonds to the glass.
