Proximity Light Sensor Flex Cable for Realme Narzo 90X

The Proximity Light Sensor Flex Cable / Patta in your Realme Narzo 90X 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 Realme Narzo 90X.

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 Realme Narzo 90X.

Yes. The sensor integration, cable dimensions, connector type, and routing are model-specific. This listing is designed for Realme Narzo 90X 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 Realme Narzo 90X. 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.
