Yes, the MIC 2 is located near the top and when I talk right here, people can hear me very well.
But it’s much quieter than MIC 1 and every time I talk by Zoom, Discord with video, people can’t hear me cuz 2nd microphone is working.
I’d like to manualy change, which microphone has to be used.
Yes it is a problem for me too. It would be nice to select which mike to use and increase the volume of the top one.
I may have to ask official support if it is their only for noise cancellation as i see no ref to the issues in specs etc.
Hello, thank you @paucotan, and @anon9989719 and AlberJP: apologies for the late answer as I was getting new good headphones to test and see if it solved the problem: indeed it seems that I can be heard much better with headphones, wireless and wired (on WhatsApp - it seems that I now also encounter this mic issue with phone calls via normal phone connexion as well…). If somehow the problem could be solved without using headphones, it would be great as I also sometimes need to be on speakers to have other people in my physical room participate to the call with me.
HI is there a permenant fix for this yet? It does seem to be software releated as both the mic test pass and a reboot fixes it. Please help
Hi edd
This is just a user forum, if you want a fix you had better contact official support, and they could do with official complaints as they are not going to read all the posts on this forum.
if you want just other users idea etc. then this is the right place

People cannot hear me. What do you do about it.
Could you give more detail? How long has this been going on, what version, what apps are you using to produced this ~ phone ~WhatsApp etc. ? There’s lots of advice in the posts prior to your asking.
If their is no sound permanently and it’s a new problem and you tested the microphones as described in a post above, send it back.
"I had problems with the secondary microphone (Mic2) and I was given two options by the support team:
This seem to have started recently on calls on signal and the cell network.
How do I test the microphone without annoying the hell out of my friends and families?
*#*#66#*#* to show testing menu with three sub-menusIf the mics are working then there is a software issue and it seems that some apps don’t let go of the control. I had to uninstall a recording app to solve the problem.
Yet another case of FP3+ microphone issues here. I tested all changes mentioned in this thread so far, no changes. The service test works fine, the volume of playback for microphone 2 is quite lower than mic 1. My guess is some of these apps are using just mic 2 instead of both of them for background noise correction. Something needs to be done about this, the phone is unusable for regular calls without headphones with their own mic. I can’t believe it’s been going on for so long without any solutions. I’m growing increasingly disappointed with the Fairphone.
BTW when I say “apps” I even mean the telephone Android app, this also happens on regular phone calls, not just WhatsApp or other services.
The problem of "it’s’ is that ‘it’ is not a common problem going by this forum i.e. no. of complianants :: no of owners of FP3
Further given the different setups of networks, apps, Android 9/10 and version updates it must be very difficult for Fairphone to pinpoint the numerous instances and find solutions for any, let a lone a common software handover glitch. I say handover as more often that not it occurs when certain apps are invoke/installed. I had to remove a audio recording app to stop it ~ and bot only am I unprepared to re=install the app, a) it took a while to work so I’m not even sure that was the cause.
You start with “yet another case” but you haven’t stated which FP3 you have, which Android or update etc. Add to that how long have you had the phone ~ compare that date to the date you posted and what apps etc you installed since ownership etc. you can appreciate how difficult it is to help unofficially let alone how the official FP team must be see the issue as they probably have dozens of similar issues among others.
It’s a real bummer, that’s for sure.
I am also a user with a FP3 (received in December 2020) where the mic issue underwent a marginal improvement after the 077 January update, however the mic quality is still disappointing on Whatsapp calls compared to almost all other phones. When i’m shouting into the mic I sound “normal volume level” to the conversation partner. Have a ticket still active and hoping there’ll be further improvements.
Hi! I have the same problem. Both mics work, but video calls seem to use exclusively MIC2, which is too weak to be heard. Is there a way to just disable that one? I would rather try no background noice reduction than this. Video calls are right now one of the main uses for my phone, and if it doesn’t work I will have to returne the FP3 
.
I had hoped the last update would be able to fix it but no…
Hi @Sue1
yes the last update 0084 wasn’t targeted as resolving this problem but one where the call dropped on many occasions.
My daughter is about to return her phone after three months of this issue.
I note from the following that @Sarasure resolved the mic being low on calls by using a headphone only for it to move to WhatsApp. It seems clear that the mic1 control isn’t being released to the app that wants to use it.
I am using Official LineageOS 18.1 since about 1/2 year with regular updates. I believe that microphone problems were not there at that time, but that the performance changed due to an update. Nevertheless all problems are now there also with this OS version and current updates:
This is very bad situation for phone usage.
I have the same issue since I bought the FP 3+ and right away installed /e/OS. Since the FP 3 is sold with /e/OS preinstalled, I hoped to get this issue resolved fast. Maybe more details help to debug it:

What I tried but did not work
Is Fairphone aware that the problem still persists?
Welcome to the community forum.
Fairphone only support Fairphone OS, /e/OS is supported by the e foundation, Fairphone OS updates are Fairphone OS updates and don’t automatically translate 100% to /e/OS updates.
So the question would be whether the e foundation knows of this problem.
If the issue doesn’t already exist at Issues · e / Backlog · GitLab, then somebody should open an issue there to get /e/OS developers to take a look.
Thanks for the suggestion, I have created a bug report in the eFoundation GitLab.
Sorry, I got confused. I thought Fairphone sold it with /e/OS, but in fact the eFoundation sold the Fairphone with /e/OS preinstalled, i.e., the other way around than I (falsely) remembered.
So far it seems that only LineageOS and /e/OS are still affected by this bug.
/e/OS support is wondering if this bug still persists with the stock ROM (Fairphone OS)? I wonder since the last post from a stock ROM user is already a year ago.
Is anyone with the stock ROM (i.e., still using the pre-installed operating system and not a different one like LineageOS or /e/OS) still having this issue?
Yes since purchase in Oct 2020. There was an ‘echo’ issue that seemed to be resolved after a couple of updates, early 2021, but no other audio issues in the UK on EE , network or Wi-Fi calling, hands free or WhatsApp etc.
