Restore proximity sensing, ambient light response and secondary microphone function on the iPhone 13 Mini with this genuine Apple Proximity Light Sensor Flex Cable, part 821-03348-04, supplied in reclaimed condition. Professionally removed from a working donor device, fully cleaned and bench-tested by our QA team, the flex delivers Apple's original sensor calibration and microphone response — the same hardware fitted at the factory.

This single flex carries three critical components: the proximity sensor that turns the screen off during calls, the ambient light sensor that drives auto-brightness, and the secondary microphone used for noise cancellation and FaceTime audio. Replacing the assembly is the standard fix when the screen fails to dim against the ear, when auto-brightness behaves erratically, or when call audio quality drops on speakerphone or video calls.

Common Faults Resolved

• Screen failing to switch off when the phone is held against the ear
• Erratic or non-responsive auto-brightness
• Poor noise cancellation or muffled FaceTime / speakerphone audio
• Liquid damage or impact damage to the proximity sensor flex
• Failed prior repair using a poorly tested aftermarket flex

Key Features

• Genuine Apple component: reclaimed from a working donor iPhone 13 Mini, not an aftermarket copy
• Three-in-one assembly: proximity sensor, ambient light sensor and secondary microphone on a single flex
• QA-tested: every flex is cleaned, bench-tested for sensor and microphone response, and verified before dispatch
• Plug-and-play fitment: standard flex-cable connection — no rework needed for sensor and microphone restoration

Important Notes

• Face ID will break with a straight swap. This flex is part of the iPhone 13 Mini TrueDepth system and is paired to the device's original logic board. Fitting a reclaimed flex from another donor device will disable Face ID on the recipient device.
• Microsoldering required to retain Face ID. The TrueDepth pairing IC must be transferred from the customer's original flex onto the reclaimed flex by an experienced microsolder technician. Without this transfer, Face ID cannot be restored.
• No software fix is available. Apple's Repair Assistant, third-party pairing tools and iOS calibration routines cannot restore Face ID for this part. This applies to all iOS versions, including iOS 26 and iOS 26.1.
• Parts & Service History entry: the device may display a notification under Settings → General → About → Parts & Service History indicating a non-original part. This is informational and does not affect proximity, ambient light or microphone function.
• Bench-test before final fitment: connect and verify proximity sensor response, auto-brightness and secondary microphone function before sealing the device.
• Installation should be carried out by a qualified technician using suitable heat, separation and ESD-safe tools to avoid damage to the chassis, flex cables or logic board.
