Microphone not working properly

Thank you for the link to support, amoun, I have now written to them.

My husband had ordered a fairphone 3+ which arrived today.

The first thing I did after recieving my phone was to make the recommended system update.

My husband did not. He immediately installed Telegram and made a videocall to me. I could hear him fine and he had trouble hearing me. He also called another person and it also worked fine.

We checked the build numbers on our phones:

My husbands: 8901.3.A.0054.20200929

Mine: 8901.3.A.0066.20201119

He then made the system update on his FP3+ so its the same build number as mine. Then we made a Telegram videocall and now I could hear him badly, so now both phones have the mic1/speaker problem.
So it must be a software issue.


Thanks for the detailed info. I hope you told support all of that !

I have the same issue with my Fairphone 3+

It’s a relief to hear it might be a software issue. In that case it might eventually be fixed by an update without me doing anything :smile:

The last video call I had (through WhatsApp) the person could hear me okay. She said I sounded a little distant but that’s much better than calls I’ve had with other people.

I have the same issue after updating on FP 3.

Do you mean you didn’t have the problem before the update?

As this topic is a ‘microphone’ issue, which is rather broad, would you

  1. clarify the version numbers before and after the update,
    the network you are using,
  2. does it happen to all your contacts, as it may be related to their network
  3. is it happening only via wifi calling with What’s app or other instances
  4. What network are you on?

The only issues I have are irregular and consist of two issues only during wifi calling via WhatsApp, I sometimes get low volume early in the call which resolves itself and less frequently echo.

Build 8901.3.A.0077.20201221
Android 10
happens to all contacts so far on all types of calls - phone network or wifi calling via telegram/fb messenger

I have just had problems using WhatsApp the person I call can hardly hear me. I note that under Settings > Sound the Call volume is very quiet on max.

I have this issue since the last system update - colleagues who could hear me fine on Zoom before now struggle. None of those settings have changed and Zoom is up to date.

Have the same problem - not with Zoom and WhatsApp (I don’t use them), but with Jitsi.

I just realized that the problems described in this thread could be the same as I mentioned in a seperate thread. So I doubled the threads about one and the same problem; sorry for that.

But I guess it clearly shows that microphones are really not working properly for some apps since the update.

This will hopefully be fixed in a few days. Have a look here and here.

Yes, it is really sad to have that kind of issues with an expensive phone. But fingers crossed that all these problems are fixed soon with the update!

Unfortunally the update NOT solve the problem, the quality is a little better but not Ok. Any idea when new upadte will come,

What exactly is the problem you have? If it’s related to hands free video type calls via WhatsApp etc this update wasn’t designed to sort that.

Hi @dmichel1

For info on the WhatsApp issue see

and then use the link in the second post for up to date user info or use the link below

Hello everyone,
I also received a new FP3+ and had the same problem. I have the last FP3+ android 10 update… It is a problem on Signal, WhatsApp, kMeet, Google Meet, etc. So this should come from the microphone itself.
Has anyone solved this problem somewhere in the forum?

Your post isn’t clear. You say the microphone isn’t working properly but how do you know? Do you mean that the recipient of you call can’t hear you very well, that is different.

To be clear, do you have the 0084 update which was designed to fix the audio on phone calls not WhatsApp. This is an ongoing issue and is not a microphone problem per se. You can check the microphone via the phone call keypad.

Dial *#*#66#*#* >Service tests > Test single > Microphone

There are two mics and the second one is the noise cancelling mic and is quite.

It seems that often, for some people, when using WhatsApp, a previous demand for the main Microphone 1 is not released and so only the top microphone for noise cancelling is being used resulting in a very low volume at the recipients end.

As I said this seems due to other apps not letting control of the main mic so you may want to disable other apps that may intertere, ~ I removed a recording app ~ and reboot the phone. Try a WhatsApp call again before you re-enable other apps and you main find the issue.

This clearly shouldn’t happen and Fairphone will need a few requests from users to take it an important issue to resolve software wise.


@yond4im I’m going to provide links to posts that reflect this issue, I may update it during the day. All the best

There are others post that better reflect the issue as not a Microphone issue and you may prefer to contribute to those topics

@amoun thanks for your reply and sorry if my post is not very clear.

As I had exactly the same problem as the others with the microphone i.e. once the speaker is activated on a video call (WhatsApp, Signal, Google Meet, or any other Zoom type application), the contact person can hear oneself talking with a more or less loud echo depending on the day… Also, on WhatsApp and Signal and sometimes on Google Meet, they don’t hear me loud enough.

I’ll try your suggestion but honestly it’s not acceptable to tinker with the recording app and release the mic even if one has a “Fair” and sustainable phone…

So yes, I’m sure it’s either a microphone filter issue, a hardware issue or maybe a software issue that should have been fixed by now.

The problem occurs with all my contacts, regardless of the software I use.
I have exactly the latest version (Fairphone OS releases for FP3/FP3+ – Support)

@amoun I also tried out the service tests on mic 1 and 2. It seems to work properly. Maybe this is due to a bluetooth speaker connection as it was detailed in the following post:

As we said together, they should notice this problem and fix it with a new update…
