For Samsung A5 , A520 2017 - Replacement Ambient Light Sensor Flex Cable

Restore automated display luminance and proximity detection with this OEM-Spec Ambient Light Sensor Flex Cable. Specifically engineered for the Samsung Galaxy A5 2017 (SM-A520), this component integrates a high-sensitivity photodiode and an infrared proximity emitter. This assembly is essential for resolving hardware failures such as "Adaptive brightness not responding," "Screen remaining active during calls," or "Inaccurate auto-dimming" resulting from sensor oxidation, dust ingress, or flex cable fracture. The module ensures the display driver receives precise Lux measurements to maintain optimal visibility while maximizing power efficiency.
