5 Signs Your Device Needs This Repair

  • Callers constantly complain that your voice sounds muffled, distant, robotic, or like you are underwater
  • Voice memos recorded in the Voice Memos app play back with faint, crackling, or completely silent audio
  • Speakerphone calls work normally (using top mic) but standard handset phone calls cannot hear you
  • Siri fails to recognize voice commands ('Hey Siri') unless screaming directly into the phone
  • Visible dark grime or pocket lint lodged inside the small holes to the left of the USB-C charging port

How Our Technicians Complete Your Repair

Directional Microphone Diagnostic Sweep

Technician tests all three microphones independently (handset mic, speakerphone mic, and camera video mic) to isolate the faulty channel.

Ultrasonic Cavitation Cleaning

Specialized solvent is applied to dissolve compacted sebum and pocket lint clogging the acoustic mesh without liquid entering the chassis.

Micro-Vacuum Extraction

High-pressure reverse vacuum extracts loosened particulate matter out of the acoustic chambers.

OEM Flex Replacement (If Hardware Damaged)

If the MEMS microphone element is burnt or liquid damaged, a fresh OEM sub-flex is installed, followed by decibel gain verification.
