Just go to the Voice Memo test again. It's good if the recording starts.

How to repair this? Why this happening to me? 
I wrote an article and a video here before.

Always send it to a real professional for repairing this issue.

"Having the tools to repair doesn't mean having precise surgical skills and experience."

Send to the wrong shop you will end up having more problems in your iPhone. I saw a lot of customers ended with the problem of "no service". I repaired the mess they created at a higher cost.
Some even shorted the CPU and the iPhone unable to power on.
It is very dangerous by just watching YouTube try to fix it without properly trained.


Send it to our shop for instant repair and collect it on the same day.

We provide ONE year warranty
But not valid if the board been "repaired" by others.
and also not for water damaged.

In the iPhone repair community, we called it iPhone 7 Audio IC Disease.

Go to VOICE MEMO and click record
iOS 12 would show this message - Recording Failed. No Audio Device Found.
or
It would just freeze there and won't start recording

We made a video and how to repair this issue. 

Why it happened?

Because you drop it too hard or bend it. One of the audio IC solder joints is broken.
Not entirely your fault. It's the design issue and they didn't expect it. Don't worry, it can be fixed permanently by a professional micro-soldering technician.

Advice:

DO NOT send to normal shop repair this issue. The audio ic is located behind the Baseband and CPU. You don't want they brick your iPhone.

So many cases that I repaired their failed attempted job. They "accidentally" overheated the components around. They either caused the iPhone became No Service (Baseband shorted) or unable to power on (CPU shorted).

Ended up with a higher cost to repair and time wasted.

How do I know they are professional? 

Easy to know if they are able to provide the repair in a few conditions below:

1. Repair on the same day. 1-3 hours between. (Too fast is not good, because they won't bother cleaning, put back the shield and water-resistance seals, blah blah)
2. Warranty period is long (we provide one year warranty)
3. If the device is dead by their hand, they replace the motherboard or repair it fully without need you to pay more.

iPhone 7 / 7 Plus Audio IC repair

This photo is an iPhone 7 Plus. The smaller iPhone 7 also has the same flaw.

Let's take off the IC and look closer with a microscope

99% of audio disease is because of this pad broken. Even it's not missing, we MUST still need to rebuild a new track for it. I saw a lot of technicians didn't rebuild this track and the customer keep coming back with the same problem.

The technical term of this method is called "jumper".
Jumper it to the Resistor R1103

C12 - I2S_AP_TO_CODEC_MCLK
This is a very important line that would cause the malfunction of the audio codec totally.
It controls the microphone and sound codec. You still have ringtone working but no sound when calling.

So this is the fix that must be applied before we put Audio IC back

We still can see the green PCB glue in that area after repair.
If this iPhone suffers another serious fall damage again, it would still be working fine.
The screen should be broken first before this problem reoccurs again.

This solution is a permanent fix method. We'll cover this problem for 1 year if it happens again.
