UV Film Lens for Light and Proximity Sensor for Apple iPhone 4S

The UV Film Lens for Light and Proximity Sensor for Apple iPhone 4S is the small optical window applied to the inner side of the front glass, over the ambient light sensor and the proximity sensor. It lets the signal reach the sensors correctly, allowing the screen to switch off during calls and the brightness to adjust automatically.

Replace it when the original lens has been lost or damaged after a glass or display replacement, when the screen stays on as you bring the phone to your ear, when your cheek triggers buttons during calls, or when auto-brightness no longer responds properly.
