iPhone 15 Pro Ambient Light Sensor Installation

Use tweezers to reposition any adhesive that may have covered the ambient light sensor during removal. The adhesive should form a border around the raised white rectangle.

If the adhesive was damaged or stayed with the old screen, replace it with a 1 mm‑wide strip of thin, double-sided tape along its bottom border.

Align the ambient light sensor with its recess in the back of the screen.

Use a spudger or your finger to place the ambient light sensor into its recess.

Use a hair dryer or heat gun to soften the adhesive under the ambient light sensor and its cable. It only needs to be warm—not hot.

Use your finger to press down the ambient light sensor cable.

Use tweezers or your fingers to place the ambient light sensor bracket, foam side down, aligned with its screw holes.

Use a Phillips screwdriver to install the two 1.4 mm‑long screws securing the ambient light sensor bracket.
