"This is the common iPhone 7/7+ audio ic issue. The good news is that this problem IS REPAIRABLE.

The independent repair community has fixed thousands of these cases and we now know exactly what the specific defect is now. The C12 pad for the master clock line of the audio ic chip on the logic board gets stretched/lifted/pulled/weakened simply from normal use of the phone. This is a very similar problem to the iPhone 6 plus touch disease. Both defects share the same underlying biology—-the iPhone logic board is screwed down into a relatively flexible/bendy housing and this causes the logic board to experience flexion forces that it can’t handle. (Similar in concept to bending a paper clip back and forth a few dozen times.) In similarly sized Samsung devices, the logic board “floats” in the housing and is not subjected to these same forces.

The repair is to desolder the audio ic, add a thin wire to enhance the connection of the C12 pad to the master clock line, reball the audio ic and resolder it the board. With the microjumper in place, the phone becomes immunized against the recurrence of this classic problem in the future.

We have trained hundreds of microsoldering students in the US and Internationally, so people will have an increasingly good chance of being able to find a local logic board repair expert that can fix their iPhone 7 audio issue since the manufacturer never will. If you can’t find a local microsolderer, then there is always mail in repair."

How I fixed this without sending it to have audio ic done I remembered iPhone 4 had a problem with audio chip and you had to put something on top of chip and put the lid back on to hold the chip down which worked a charm all I did on iPhone 7 was take logic board out locate the chip but don’t take the black tape that covers it off just rub it ware the chip is so you get the outline in the black tape then I used the card from cigarettes papers I cut a strip exactly the same size then folded it 3 or 4 times the same size as the chip I used double sided tape to stick it on top of the outline on the black tape put the board back in put all the standoff screws back in attach screen a test before fully putting back together my phone is still working well with just that bit of pressure

Apple is aware of this problem. If you take it to them they should attempt to fix it or replace your iphone for free.

"Guys I figured out how to fix your phone without buying a new one. I have the iPhone 7 Plus and suffered from the speaker screen being frayed out, I was able to make and revive calls but couldn’t here who was calling and they couldn’t here me.

i went to the repair store they told me my audio jack was broken and I’d need a new phone.

So I stumbled upon this fix….

sign out of your Apple account, reset your phones settings under General system. Then sign back into you Apple account.

my phone worked immediately after this, let me know if this works for you!"
