[Q] Weird microphone issues - Android Q&A, Help & Troubleshooting

I have recently purchased a Lenovo IdeaTab A2109-F which I was quite happy with, since this was the first time I have used an android tablet as I am coming from iOS background.Before I bought the tablet, I read that id had double microphone in order to make voice calls such as Skype clearer. Now , at first it seemed all good and I had people saying that the audio being received is clear and crisp on the other end of the call.
However after 2-3 mins in a call (every call) the microphone then goes really weird and audio being received from it becomes mumbled until it completely degrades where it seems like just random noises, sometimes it even goes all quiet. What I have noticed however , if I blow into the microphone it then goes all good again.
At first I thought it was a Skype app issue and so I downloaded a microphone voice recorder (memo recording sort of app) and same observations were made where voice being recorded completely degrades within 3 minutes of the recording, where blowing into the microphone temporary fixes the problem until it happens again after a minute or so.
Now I am lost here , I really like the tablet and I really doubt it's a hardware issue for some reason. I have a suspicion that something is either upping/lowering the sensitivity of the microphone and where blowing into the microphone seems to then readjust it.
I really hope somebody could help me out, maybe there is an app that allows to change microphone settings , or maybe something else that I could try out.
Thanks for your time! :good:
P.S Android Version: 4.1.1 and latest Skype app. I also tried upgrading the firmware, same problem was observed.

I still have the same issue on my Lenovo A2109. Skype, Line or any internet call, voice degrades within 8 - 10 mts and I had to end the call and re-do the call again. VERY ANNOYING... I thought it was just my tablet. I didn't try the trick of blowing into the microphone. Thanks for the tip. Did you get a solution yet? I thought upgrading would help. But thanks for confirming.

[Q] Mic Problem: My voice not going through in calls, same goes for voice recording

Hi xda!
First of all my specs:
I9300 International
Unofficial CM 12 build made by JustArchi and Moster7
My problem is that my voice does not go through in a call, the person who I am talking says that he cannot hear me bur I can hear him. Same goes for voice recording, the only thing that is recorded is some sort of static. But in video recordings, well, it records my voice but with some static.
I tried cleaning both the mic holes with a safety pin by poking the holes carefully, but it did moy work.
I cleared the data of every app that uses voice recording, no effect.
Help pls.

I've had the same problem with my International GT-i9300 since the summer of 2013. It was built in the UK, France to be specific, and I use the phone in the US.
I had done plenty of research back when the problem 1st surfaced and eventually gave up, but I have returned to revisit this case, since replacing the microphone doesn't work, of course I knew that back then, so I was hoping that new information has been discovered by the android gurus amongst us by now.
Good luck, and please hit me up if you find anything out on your end and I will do the same!
If the fault is still present after a full wipe and flash stock firmware then you'll need a new motherboard, or phone.
I had this issue with custom kernels that used audio mods like Boeffla sound. Disabling Boeffla solved the problem.

XA Ultra Dual microphone issues

Hello guys,
My XAU Dual showing microphone issues during making calls! when I make a phone call my friends keep complaining about barely hearing me (very low voice) or my voice is like someone talking in a deep tunnel with too much echo ..sort of that!
here are some things I tried to fix the issue but all failed to fix it:
1- I tried factory resetting my device
2- tried repairing my device software using Xperia Companion
3- tried disabling audio enhancement (ClearAudio+ ....etc)
4- in settings>call>SIM>Equalizer ...set to normal
5- tried looking for microphone noise suppression in settings.. can't find it
Didn't drop my device & never exposed to any fluids!!
Tho, I ran diagnostics>tested my microphone, one time I hear my voice good, then gave it another try later on & the microphone recorder a very low sound!!
Am really outta options here & this issue really sucks
My device model number is F3212, running android 6.0, build number 36.0.B.2.146.
Any ideas..
I've been experiencing this problem on two different XA Ultras. The microphone seems to switch to the one on the top of the phone so if you hold the phone upside down people can hear you. I've had to switch to speakerphone output to talk to people when this happens. Switching back to phone from speakerphone sometimes makes it work normally but not all the time.
I suspect it has something to do with an app that is running earlier, maybe google play music or OK google.
I have tried reset and it doesn't help. The problem comes back.
There is a similar if not identical issue on another Sony phone, the solution being to turn off microphone noise suppression. I haven't tried this.

I didn't notice that flipping the phone or switching to speaker output might work, gotta try it first.
What bugs me the most is the fact that I can't find anything related to disabiling microphone noise suppression at an section of this device settings!
Am using a headphone currently & waiting for Android nougat to hit the device & hopefully fix the issue.
This problem was never there when I first used my device out of its box, but later on it appeard after may be 2 upgrade patches of Android 6.0 few months later.
Waiting is my only hope...

Sound quality problem?

Hi.
I recently bought a Xiaomi Mi 10 and before using it I went through updates (so I cannot say how it was before).
I have noticed that when reproducing an audio or voice note in apps like WhatsApp or Telegram, the sound is very low and sometimes it reproduces them well and then bad and so on. It also happens in games, where a MI 9T with just one speaker is louder than mine. I have noticed too that it happens when increasing the general volume. At 60% you can hear the bass and amazing sound but if you increase it, the quality goes down and you hear too much treble.
I have been reading that I'm not the only one with this problem (https://forum.xda-developers.com/t/speakerphone-loudness-clarity.4049087/), but I wanted to know if this is a common mistake or just some units.
Thanks!
Here a video:
Yes seem like guys are more interested in modding but ignore daily usage real problem. I confirm this problem and I ask you if you have big problem using proximity sensor when you call or want to ear vocal WhatsApp message without speaker. For me have a really bad setup

Totally agree. People is more concerned about ROMs and custom recovery than daily usage.
I have experienced that sometimes in calls I cannot make the sensor turn off the screen. Or in WhatsApp sometimes it goes crazy, but not frequently.
I read that you can solve that problem going to the dial and using the code *#*#6484#*#*. Then go to proximity sensor (23), cover it to check it goes from 0 to 5 and press ok and exit.
Hope you can solve it.

Question Calls not working properly on calls and whatsapp calls.

Hi there people.
I've got the following issue. If anyone has this issue or has fixed it let me know.
Calls seem to be interfering with my mic. Sometimes my voice doesn't go to the other end even though normal call or whatsapp call. They might hear 1 word then nothing from me for a few seconds then a word or two and it sometimes sounds like a clicking noise.
I've called my self too and I can't hear anything on my RM7 but whoever I call can hear the clicking noise and sometimes nothing from me.
Sometimes I can't hear the other person too. It cuts out.
Same with normal calls and whatsapp calls.
Continuing my testing, I can send voice notes without issue and receive them and play it via rhe earpiece without issue too. Even voice recording and video recording the microphone does a good job only in calls it bugs out.
Continuing my testing
Works fine with headphones connected. But mic and earpiece work fine when used by voice notes and video ect
I don't know if it's a coincidence or not but I have the same issue. It started around last week.
I cleaned my speakers and mic thinking I got dirt build up. But it's still the same.
It seems like a software issue. Looking at the patch notes in latest OS update (NX679J_UNcommon_V3.16) for me, they have listed "Repair: possible issues with calls in some scenarios". I don't know when they released the update and when I applied it to my phone but that could be the reason for this issue too.
After reading your post I tried regular calls with headphones, speakers and video call with Google meet. They all work fine.
For call on speaker, as soon as you turn the speaker off it starts acting up again.
Hopefully they will fix this issue soon.
From my testing it seems like its an app or something interfeering with the calls. I started the phone up in safe mode (no 3rd party apps only stock ones) and the issue was gone, so the issue is a app related issue, thinking its a virus I just reset the phone to factory and all is good now. I didnt find what was causing it.
Thanks for an update.
I will play around a bit and if it doesn't work out then will do the same.

Question Popping/crackling sound during calls on multiple apps [SOLVED]

Every couple of minutes I am getting a loud pop/crack sound during normal calls and the same behaviour on Whatsapp and Viber calls.
I tried both on speaker and without and the result is the same. I am running all the latest updates. The adaptive sound is disabled.
Also tried Stealth Audio Player to hear both the external and internal speaker on Youtube videos and I can't reproduce it except sometimes it pops when a video is started. I also tried recording my mic and it sounds clear without this popping.
Is there anything else I can try to fix or debug this issue? It sounds like it is trying to record or adapt the sound while on call even if the adaptive is off.

This kinda sounds like the problem I had, but ALLLLL the way back to my Pixel 2 XL!
If you're rooted, you can try what worked for me below -- although, I'm not up to date with Viper4Android (V4A) and I believe it's either EOL or is in the process of being updated to work in x64 architecture or there are newer updated branches or something... But if it's possible to lower the frequencies, you might luck out like I did on the taimen...
I Found a Speaker Distortion Fix
Like many, my phone has the lower speaker distortion on speaker phone calls and general audio, like YouTube, when turned up high. If you are rooted, I have found a solution to all situations except speaker phone calls. I installed Viper4android...
forum.xda-developers.com
Thanks for the help. I can hardly hear any issues while on youtube. There is noticeable pop when videos ending or starting. Some people are reporting motherboard issues with Pixel 7 leading to similar problems. I am trying to find if it is a hardware or software issue.
After further investigation it looks like interference. If I disable the mobile data and WIFI it seems to be a lot better. After 16 minutes call it was a very faint pop if at all. Does it sound like it needs a motherboard replacement or a future patch might fix it. Update: still happening regardless of connectivity on both the inner and outer speaker. I am going to RMA for motherboard replacement.
