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.

Some common symptoms include:
- Voice Memo app cannot record- record button will be grey or say “No audio devices found”

- No Microphone, or Speaker button grayed out during a phone call

- 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
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
