Fixing the microphone issue

I am suffering the microphone issue and there is not official service in my country, so, Is there a way to fix the main microphone issue?

Thanks!

Update (05/18/2017)

Testing and testing, as nothing else could be done, i was able to record my voice using the main mic. My guess is that it still works, but something is interfering with the sound entering the phone.

Should I open it? Why should I look? How is the process of unstucking the diaphragm of the mic (as I read in the google forums that it can be one of the causes).

Thanks!

Update (06/30/2017)

Finally, I bought the Charging Port PCB, I replaced it and the mic works really nice again. The main mic is in that PCB, so I finally replaced my phone. :)

Have you tried a factory reset? If not, do so.

Google acknowledged that some of the "microphone problems" were due to a "hardware problem" .

see Google Help Forum here: https://productforums.google.com/forum/#...

I have had luck toggling the speaker phone on and off on mine, but that only solves the issue for that call.

による

I've tried everything, factory reset included. The only thing that helps is, as Christopher Williams says, toggling the speaker phone on and off. I hope there is a solution, I need to fix it.

Thanks everybody for the comments.

Watching the teardown of the Pixel XL, I can see that the main Microphone is attached to the "Charge Port PCB". If I can buy (where?) and replace myself that pcb, is it possible that I can solve my problem?

Any idea is welcome, I don't want to lose a phone like this for a relative small issue.

による

So, anybody recommends a place where to buy the whole PCB? I can't find it in stock anywhere.

Thanks!

Ifixit's teardown is for the pixel XL. It is likely different for that phone. Besides, replacement of the microphone wouldn't cut it. A microphone is an analog device, like headphones. That means, no digital signals are being sent between the mic and motherboard. So if toggling the speaker phone fixes the problem, it can't be fixed by replacing the mic.

Try downloading audio recorder from the play store. Take a recording and see if you can hear it.

If you can hear from the recording, installing a third party phone app should fix it. If you don't have it already, install your carrier's phone app.

Hope this help!

Hi! Thanks for answering. I believe I didn't understand clearly (english is not my native language). So, to clarify:

When I make or receive a call, I can only talk using the speakerphone. When in a call, I turn on and off the speakerphone, the other person still can't hear me.

Using audio recorder apps, I just hear noise (when selecting main microphone). If i knock on the mic, I get that sound on the recording. When selecting camera mic (?), I can record audio just fine.

So, my idea remains. If i could buy the "OEM Google Pixel Charge Port PCB" somehow, replacing it should fix my problem, right?

@nicomibanez would you prefer if I used a translator?

Probably not. You can try it though.

による

@pccheese Translators aren't really accurate, I should read better/slower next time.

Thanks for your help!

Hey guys i found a fix for the mic problem IF YOUR PROBLEM IS HARDWARE RELATED. So through some research I saw that the problem is that the Qualcomm WCD9335 audio codec chip located on the back of the motherboard has a tendency to have some of the solder joints disconnect and cause audio issues. I found a fix but its a little bit of work. So you basically need to reflow the solder on the audio chip to restore the connections. I accomplished this by removing the motherboard from the phone and heating the entire board for about 30 secs with a precision heat tool and then covering the board with foil except for a cut out where the audio chip is located. I heated the chip for another 20 secs and then waited for the board to cool down to room temperature before reassembly. So far it seems to have worked, its been about a week. I used the tear down of the google pixel XL as reference when I did this. NOTE: DO NOT OVERHEAT THE BOARD, USE MINIMAL HEAT AND GO SLOW!

I'm asking for a techie friend to do that. My pixel is still under delivery to him.

How long have you been using the phone since you do this fix? Yours is XL or the non-XL?

による

3 weeks and the fix works for both sizes of the phone

による

Hi Brendan,

on behalf of my friend here (and mine of course). Could you highlight the location of the audio chip on the motherboard. We want to be double triple confirmed so that we won't mess anything else. If it doesn't trouble you that'd be awesome and greatly helpful.

Thanks!

This is a pic from the ifixit tear down of the pixel XL, although it is not the non-XL the components are all located in the same relative locations. The chip in the lighter blue square near the center of the board is the audio chip.

Hey bro, pixel user from Malaysia here. Just wondering about your fixed microphone. Does it still working good? Do you think the problem will return again?

Also, does your headphone jack work, mine does not and i suspect it happens in relation to my microphone as well. Will changing the PCB fix this too?

Thanks!

My Pixel phone just had the issue with the microphone today. All of the sudden the microphone is not working while making phone calls/WhatsApp call. I tried factory reset but the issue still remain the same. Anyone can help me? I have been using this phone for 14 months.

I also am having the microphone issue. Since my Pixel is nearly 15 months old, neither Verizon nor Google will do anything for me. Any advice would be appreciated.

If you are having the same issues and haven't tried yet, Verizon did a software update, turned of HD calling, installed a new SIM card, and did a hard restart. Google recommended taking the phone back to factory settings. None of the above worked for me but you may what to try if you haven't already.

Hi,

This was a bad experience with google pixel. All of a sudden microphone is not working after 13 months of usage.

Went to Service center to address the issue and got that a complete Motherboard replacement can fix the issue. I didnt go for this as its costs me more.

I looked into several blogs on this and finally got a solution at lower cost.

'Qualcomm WCD9335' chip replacement can fix the microphone issue.

Hello! I have the problem with mike, 3.5 jack and acoustic speaker, so nothing can hear me, and also I can not hear anything, but if I turn on a loud speaker so I can hear all, but no me.

I have just solved the problem in safe mode of my pixel phone, but I can't use other apps unfortunately.

Who also solved the problem with mike or acoustic speaker?

Hi,

I have this same problem, My pixel freeze and reboots when someone calls me or when I tried to play some sound via build in speakers.

So i've buyed a replacement daughter board ( since i've read that where lies the problem ).

With this replacement the phone stops to freeze but the microphone wont work anymore, I don't know if the problem its with the new daughter board or in the maid board itself.
