Product Name: iPhone 13 Series Sensor Flex Cable Assembly

Compatibility: iPhone 13 Pro

Replace this flex cable assembly to resolve issues specifically related to sensors, such as:
Malfunctioning or unresponsive auto-brightness adjustment for the display.
Failure of the proximity sensor (screen not turning off/on during calls).
Abnormal operation of the ambient light sensor.
Physical damage, such as a torn connector or broken traces on the flex cable.

Professional installation is highly recommended.
After installation, you must thoroughly test the following:
Auto-Brightness Test: Move the device between bright and dark environments to verify the screen brightness adjusts automatically and smoothly.
Proximity Sensor Test: Make a phone call or use a diagnostic tool to check if the screen turns off immediately when an object is brought near the top of the screen and turns back on promptly when the object is removed.
Ambient Light Sensor Test: Check if features like True Tone or screen brightness respond correctly under different lighting conditions.
System Diagnostic: Go into device settings or use a professional diagnostic tool to confirm all relevant sensors are recognized by the system without errors.
