Proximity Light Sensor Flex Cable for Oppo K9x 5G

The Proximity Light Sensor Flex Cable / Patta in your Oppo K9X 5G is a ribbon cable assembly that integrates two sensor modules — the proximity sensor that detects when the phone is held to the ear during a call and turns off the screen to prevent accidental touches, and the ambient light sensor that measures surrounding brightness and adjusts the display accordingly. Both sensors are mounted on a single flex cable connected to the motherboard on your Oppo K9X 5G.

Signs include the screen remaining on during phone calls causing unintended touch inputs with your cheek, auto-brightness not adjusting when you move between bright and dark environments, and the proximity sensor not responding in sensor testing apps. If both proximity and light sensing fail simultaneously — particularly after a display replacement — the flex cable or its connector is likely damaged on your Oppo K9X 5G.

Yes. The sensor integration, cable dimensions, connector type, and routing are model-specific. This listing is designed for Oppo K9X 5G only. An incorrect flex cable will not position the sensors correctly relative to the display cutouts — causing the sensors to function poorly even when electrically connected.

Yes — critical. The proximity and light sensors must align precisely with their corresponding openings in the display frame or front housing of your Oppo K9X 5G. Even a small misalignment causes the sensors to perform poorly or not at all. Ensure correct positioning during installation before closing the phone.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Flex cables showing physical damage from improper installation are not covered under warranty. For more information, check out SAHII's Return Policy.
