iPhone 7 and 7 Plus – Audio Problems No Speaker / Greyed out Speaker

 We can fix it!

The iphone 7 and 7 Plus have a latent flaw which you may run into. It’s similar to the infamous “Touch Disease” which was extremely common in the 6 Plus. It requires motherboard repair to fix.

Audio Codec Chip failure has a variety of possible symptoms. However if the Voice Memo app does not work properly it’s almost guaranteed to be this issue.

Some common symptoms include:

  • Voice Memo app cannot record- record button will be grey or say “No audio devices found”
  • No sound when recording/playing videos from the cameras or will say “Recording Failed”
  • No Microphone, or Speaker button grayed out during a phone call

Some symptoms which may or may not be Audio codec include:

  • iPhone boot stuck on the Apple Logo, maybe finally booting after several minutes
  • no sound from the Speaker
  • Static noises coming from ear speaker
  • Headphones don’t work
  • etc.

What’s the flaw and what’s the fix?

The audio chip responsible for interacting with the speakers and microphones is placed very close to the SIM Card Tray in the 7 and 7 Plus. It’s believed that the board is less stable along the edge of the tray and will over time with enough flexing of the phone can crack a trace to a key pad on the chip.  Here’s a diagram of an iphone 7 Plus:

The repair is removing the audio codec IC, adding reinforcing wires on top of the traces that tend to crack, and putting the chip back. Sometimes a new chip is required
