Hi guys, I got an on going issue I can't manage to fix, for a very long time.
I tried all types of MIUI versions including the latest 10.3.5, and all Betas up to 9.6.27 firm+ven & ROM but I think it is deeper in kernel/Firmware level than ROM.
I even tried Pixel experience ROM..
the Issue is that on handsfree/loudspeaker voice/video calls (Skype, LINE, WhatsAPP, regular Voice via SIM card, etc.) the other person on the other side of the line claims that they hear the sound metallic and a bit distorted,
but the real problem they claim all the time my sound breaks and it is impossible for them to understand a full sentence because of those breaks.
the Issue of sound distortion and breaking up only happens on the speaker calls (hands-free).
Hands-free calls regardless to what program. it could be regular SIM card call, WhatsAPP calls, skype, whatever, you name it. it is on all, as long as it is speaker/hands-free call.
both Voice calls and Video calls, all suffer the same
when NOT on hands-free. e.g. using headset (wired or Bluetooth) or just holding the phone to my ear, all works great, sound is perfect and no breakup.
that is true to all call types (SIM call, WhatsApp, skype, etc.)
after deeply investigating, all the signs points to the noise cancellation feature the Phone's software as the perpetrator, for some reason the noise cancellation
is to aggressive which causes the metallic sound (common know sound characteristic of noise cancellation filters) and it cuts my speak believing it is ambient sound
how do you guys overcome this issue? or How do I globally remove noise cancellation all together??
here is what I found (after blocking some MICs with a masking tape in different scenarios):
Handsfree/loud speaker call always use the Top MIC only (not using the bottom one), you block Top mic, no sound on the other side of the line
non-handsfree (placing phone at your ear), always uses bottom MIC (blocking top MIC will have no effect). However , and that is the interesting part..
remember i said non-handsfree uses bottom MIC? that is true in general and in normal operation, but if you block the bottom MIC, than it would switch to top MIC (unlike hands-free/speaker that always using top MIC, no matter what and never uses bottom MIC), once you open / release the blocking of bottom MIC, the non-handsfree call would switch back to bottom MIC.
so my conclusion is since the issue happens only on hands-free/loud speaker voice/video calls and hands-free/loud speaker calls only use TOP MIC, that the top MIC is the ****ed up one.

Hello Friend. i am facing the same issue. Did you find solution to this problem?

Hello.
One day my i9100 got into water and after that it started to behave oddly. It has problems with speaker (I can't hear voice calls) and people who I call can't hear me so it has faulty microphone too. The tricky part is that headphone jack works fine, same as microphone on the bottom, I can talk with people with connected headphones and another speaker works (eg. it makes beepy sounds when I start to record the movie).
I have replaced speaker module (upper one) with no success. Same for software change (stock to CM9).
Do you have any clue what can I do with it?
Hi! First of all, I did research about this, and tried every possible solution posted in this forum, but without success...
The problem is with my s2 main microphone (down one). When making a call sometimes the receiver can't hear me, but if I switch to speaker, then its ok. So I test the mic with voice recorder app, and yes...I've mic problems...I've to scream so the mic barely detect any sound. I tried to open the rubber hole that is over the mic but nothing.... The rare thing is that if I hit the phone, or shake it, suddenly mic works fine...its like random .
what can it be??
Since my s2 has too low mic sound when I call (exept when using speaker).
Is it possible to swap the 2 microphones we got in our s2? (and how?)
I can't seem to fix this issue, it is not software related I think.
Also another weird thing is that when I record my voice (in build sound recorder app), the bar doesn't move that far (maybe 2 milimeter).
When I use sound meter and I make same noises, it shows me 30-50dB and if I blow it gets up to 97 dB.
But when I blow on sound recorder it still moves only about 2 milimeter.
Is it fixable by swapping the 2 mics or do I have to get a new mic?
Hello, first I want to apologize for my english, it's not my first language but I will try my best.
Well, I have a Blu Life 8 XL with KitKat 4.4.2 (I updated it to Lollipop, then the mic issue starts... I restored factory default config and now its on KitKat again) and after 2 weeks my mic stopped working. I tried everything on the net to fix it but nothing seems to work (disabling noise reduction, cleaning the mics, the paper on the back of the battery that works on nexus 5, disabling google search, etc).
Making tests with the phone's sound recorder I suddenly found this:
When I record something the app seems to be recording (the needle moves just as if the mic capture the sound) but when I play it only noise comes out (like ground noise, static noise).
But if I plug my earphones and play the same recording, now I can hear what I recorded, so the mic is not the problem I guess.
If I record something with the earphones mic, I can hear it with the earphones, or the phone speaker.
Also when calling, I must use the loudspeaker or the earphones becouse otherwise people can't hear me.
Any recomendation, help or something?
I've notice that when I play a music or a video on youtube, the bottom speaker (between the type-c port), especially on the bottom left doesn't have sound output but the bottom right speaker has sound output. Idk if this is a hardware problem or Xiaomi did not include a speaker on the bottom left.

Issue solved, here are the details on MIUI Forum.

They said that the left side of the usb type-c port has only microphone and the design was only purpose to have symmetry on both left and the right.
Speaker echo issue during internet (video) calls
Hello sir. The issue for me is gone for top mic when talking on both cellular and internet (Telegram call). But if I use the Google Duo app, the call recipient hear himself, sometimes there is a gain effect (for example: when the phones are nearby), sometimes I can hear myself. Can you offer some possible fixes to this? Thanks for advance, have a good day.
