iPhone 7 Audio Repair

Do you see any of these symptoms on your iPhone 7 or 7 Plus?

  • Callers can’t hear you, and you can’t hear them
  • Voice memos are greyed out or you cannot make a recording
  • Speakerphone is greyed out or does not work
  • Siri can’t hear you
  • No sounds on video recordings
  • Your iPhone takes very long time to turn on or is boot looping on the Apple logo

Due to their internal design, the iPhone 7 and 7 Plus are prone to this particular issue where all of your sound will simply cut out.  The reason this happens is that due to physical drops, bends in the frame of the phone, or just bad luck, a pad called C12 loosens up underneath the audio IC chip.  Once this pad is loose, the audio IC chip cannot do it’s job.

Apple has not done much to address the issue, nor have they acknowledged this design flaw.  They will simply offer to replace your device for $300+.  Luckily, we are able to repair this problem by adding small micro jumpers to the affected pad(s).  The repair involves getting under a microscope and using a hot air rework station to remove the audio IC chip, reball it, and add a micro jumper to the C12 pad.

Below are some microscope shots of a reballed audio chip and the small micro jumpers at the top:
