The iPhone 15 moves the front camera and Face ID hardware into the Dynamic Island cutout. When replacing a screen on the iPhone 15, the front sensor array must transfer from the old assembly. Missing this step disables Face ID, Proximity, and the ambient light sensor.
Components Inside the Dynamic Island Array
- Front camera
- Infrared flood illuminator
- Dot projector for Face ID
- Proximity and ambient light sensors
- Microphone
Transfer Steps
- Heat the top of the screen to soften the adhesive around the Dynamic Island bezel.
- Use a fine plastic blade to separate the sensor bracket from the old display.
- Clean the bracket and check for torn flex cables.
- Seat the bracket into the new screen using alignment posts.
- Reconnect the two flex cables and secure the metal cover.
| Mistake | Result |
|---|---|
| Forgetting the metal cover | Flex pops loose, Face ID fails |
| Bending the IR flex | Move Slowly message or no Face ID |
| Adhesive blocking the dot projector | Face ID unreliable |

Post-Install Test
Set up Face ID, make a phone call to test proximity, and check auto-brightness in a dark room. All three depend on the same transferred array.
Frequently Asked Questions

Physically different. The 15 standard model array is specific to its line.
What if the customer only wants a screen swap?
Explain that transferring the array is mandatory, not optional.
