People with Microphone Problem

Hello
I made this thread so people like me, with microphone problems while we are talking on a phone, gather and disguise different solutions and tips.
Just some info about this problem for those who don't have it or who aren't sure.
​
When we talk to the phone, the other party complain that they can't hear us well, like we are on the other side of the room. But It's not a hardware problem because If we record something on mono channel(uses only bottom mic) the mic works GREAT! ​
We paid for a flagship phone!​
Known Solutions till now:​1. Disable Noice Cancelling Suppression (Settings->Call->Noice Cancelling Suppression)..... Didn't really work for me
2. Use @Allodi's solution (Link) .....I tested it with my landline phone and it was working pretty good but some people complained about cracking sounds..
Feel Free to post if you have the same problem!​

I got this exact problem since day 1.

Did you find out any solution?

It's hardware problem. Coz i have this problem too.
I was sent to sony center and they fixed it. Until now it's fine and no problem with microphone anymore.
But if it out of warranty try root and edit some value in mixer_paths file.

here my thread..
**anyway microphone noisecancelling suppression can't work well.. (Here it's a software problem) when turn it on another side will can't hear you well (sound too low level)

Not hardware problem, I have had 4 Z2s so far (due to the camera not being aligned issue mainly) and I have noticed it only happens when I wash the phone and till 6 or so hours after washing it.

How can it be a hardware problem since recording works good?
Maybe older Z2s have some kind of different mic which conflict with the software?

In my case except handset it has no problem at all such as recording, VOIP (LINE CALL, FB Messenger and other) .
I have only problem at handset during call with dialer.
See in my thread it's only boost handset during call. Not boost another sound.
Try factory reset and repair the firmware if it still has this problem that's a hardware problem.
Note : don't turn on noise cancelling suppression.

If it is still in warranty. Or you can pay a bit.
Try send to Sony Center for repair this problem.
If it is out of warranty.
Try root and do replace my mixer_paths. You can see it in my thread.
Recommended : send to repair.
*How can i check when i call to other ppl or other ppl call to me.
Install call recorder app.
In my case I'm use ACR.
When you call just speak like normal and when it is end open this app and listen it.
*sound of your side will same level of other side.
If you listen your sound well and it same as other side then your pair has a speaker problem. Not your mic.
If your sound nasty or low level and other side is well then it is your mic problem.

I have the same problem. Always blamed my voice xD
Gonny try out a few things here,thanks.

Its a hardware problem i replaced the mic and everything works great . Yes it looked like its alright during video record but is not! It just looks like that because volume is higher wile recording but after mic replacement it was even better! The mic volume is lower while incall
These batches have defective mics (not all of them)
14w15
14w16
14w17
14w18
Can also appear on other batches but this are the top defective ones

Where did you get these numbers from?
Mine is 14w15 my issue is much better since I disabled the noise canceling option.

I have same mic problem
Phone is batch 14W17. I have sent my phone to Sony service two times. First time just "software upgrade" was made which did not fix anything at all. Second time they changed microphone+some other component(can't remember what) and it seemed to be working much better for couple months, no complains from other end of the call. BUT recently my Z2's microphone problem has come back as worse as it was before. I'm concidering to have it sent to be repaired again. I guess there must be some bigger flaw in design or whatever.. What do you think?

Unfortunately Z2 is the most defective flagship from sony
Here I made a list of problems:
1.Low mic during call
2.Gaps in chasis
3.Off centre camera lens 4.or camera flash
5.Back glass separating from frame in top right corner
All most every z2 has at least one or two of this problem , my first z2 had every of these problems
This is my sixth z2 and finally is aclright except really small gap in button left corner

Right, here's a really simple solution. Hold the phone correctly.
I've had this problem myself when I first used the phone and people were complaining that my voice was faint, that I was hard to hear and the reason? Two problems, the 1st, noise cancellation. The noise cancellation feature is rather aggressive and it was also compounded by the issue that I was holding the phone straight down meaning the microphone was pointing to my neck. So I disabled noise cancellation and I readjusted how I held my phone so that the microphone was in-line with my mouth (raising it 45º).
This is a long phone and the microphone is at the bottom of the phone.
There is the possibility of hardware failure but usually, you'll experience the microphone not working in other applications too.
(For reference my phone is a 14W15 device)

I sent my phone for a repair 10 days ago and I received it yesterday.
I can confirm it's a hardware problem since it is working pretty good now.
Now the problem is the noice cancelling problem, why hasn't sony resolve it already?

Problem with mic Fixed in my Z2
I had the same issue: the mic didn't work and only produce noise when call, and I tried everything I found except the root fix. But I solved the problem by connecting my earphones and try Google search while connected, it worked, then I unplugged the earphones and the phone mic was working again like a charm
I used the Sony diagnose tool and everything was Ok
I hope it help.
Sorry for my bad english.

it only happens with aosp in my xperia z2 no with other rom, not hardware problem.

Noise Reduction

Hello Friends!
I've a Problem with my phone.
When i call someone, other side hears too much noise or they hear their own voice.
When i use headphones or speaker then there is no sound.
I am on latest OTA but the problem remains the same.
There is some problem with the Noise Reduction but i could not find anywhere how to solve this problem.
Please help!

Well I don't have this issue but i'm sure the phone has something wrong in sound/mics!
Try to film a video and see how bad the sound recording is! It's like the back mic is closed or muffled!

I have the same issue plus on a headset the sound is unbearably loud even on 0 level

Microphone issue ( Maybe Noise Cancelling)

Hello guys, i'm facing a very annoying issue, since i updated zenfone 5 to lollipop, my microphone randomly and at most time, the microphone doesn't work, during a call the other side can't hear me, but if i put in speaker mode, the microphone works well, also in recorded videos or audio, there's no sound, curiously, if i speak near the upper mic hole, the other side can hear me with a low quality voice. In nexus 5 there's a similar problem, and if you change the "persist.audio.fluence.voicecall=" to true in build.prop the problem is solved, so I guess the issue is in microphone noise cancelling. I want to know if there's a way to solve this, where I can disable the noise cancelling, i searched in build.prop but i didn't find a option related to mic/noise canceling.
P.S. I already change the firmware from stock lollipop to shell rom 5.0 and did a full wipe and the problem persist.

HI,
maybe you fixed you problem yet (I'm sure you did after more than a year, but for other people having that problem).
Open claculator and type .12345+=
Go to BoardMic_Test
Make loud background noise for eg. from PC select one under youtube for phrase "industrial sounds 10 hrs"
Tap Start and talk to you phone.
Stop noise and listen results.
You may repeat procedure several times as results will satisfy you.
Try the same without noise, should be OK.
It works for me, no mic replacement, no software upgrade, no restarts, no restore factory defaults

Low mic volume

Recently tried using google assistant and it was unable to hear my voice, then tried calling to my other fone and the noticed that the mic was damn low, wasnt able to hear anything. Then cleared some garbage from the mic, both primary and secondary (something i havent done in any of my previous smartphones), google barely managed to hear something, tried calling and still the mic was very low. I am on stock 8.0 may build, without root, locked bootloader and gcam installed with camera2api enabled, voice messages via whatsapp are also damn low, strange thing is that audio while recording video via gcam, stock cam, open camera (both when camera2api enabled and disabled) is significantly better then in calls or earlier circumstances, i have tried covering both mics alternatively with hands to single out a faulty mic while recording videos and still the audio was decent. Has anyone else noticed the same?

Yes and it's driving me nuts! I didn't have issues before but lately everyone is saying they can't hear me. I did the *#*# 64663 #*#* test and it confirms the mic barely pics up my voice

The volume is so low!

Mi 9t global/ phone speaker white noise problem

Hello,
In low 1-2 level volume, i hear cracking some kind of white noise!! (Video, music, podcast) its really disturbing when you listen night and quiet place. I tried this my friends phone Poco, mi a1 same problem occurs. High volume has no problem. Is this common problem of xiaomi phones? I dont know this is software or hardware problem. Just using a week and I do not want to give the phone to technical service
Thanks for your help

Any idea?

Are you using any headphones or something maybe it is the problem
Or a network problem while buffering the video or audio

About what noise are you talking about? if you hear a small humming noise it is quite normal when Audio is active, have you ever put your ear next to External stereo speakers? They produce low noise if the music stopped or when idle but connected to a power supply, amplifier noise that is usual thing. I don't hear that much noise only if I put my phone next to my ear with the lowest volume but still it is not practical, no idea what are you trying to do or...

No, I'm talking about the phone's own speaker. When i use headphone wireless/wired, bluetooth speaker and amplifier there is no problem. This problem is present (some kind of intermittent walkie-talkie noisy sound.. i couldnt described) in every application with sound . I have tried youtube, podcast, apple music, spotify...
I use a lot to listen to podcasts at night (low volume is necessary), this problem is not really acceptable. I've used cheaper phones, I've never seen anything like it.. I went to the mi store today and tried on the same phone. there was no problem. I don't think this problem can be solved by updating miui 11 or something. (by the way I reset the phone twice and set up last miui software)
Thanks for your answers :good:

I wonder if this issue has been resolved with the new miui 11 update? Actually i don't think they are aware of the existence of such a problem.

No. Still there.

Was going to say it does not happen for me on YouTube. But... U guessed it, it does. it's not as bad and only happens on first volume level but not above that.
Then on the browser it does happen between 1-3 I think. Kind of sucks but definitely not a big deal considering the price and everything. Would be interesting to find out why though.

me too!

Today i updated my phone to miui v11.0.1 pfjmıxm / global mi9t and still has this crappy issue. ?

Is there anyone facing this issue with EU rom? ?

It's definitely issue in global ROMs. I have the same problem

I have mi 9 SE EU ROM and I have noticed the problem !

I have a MI9T Pro and having this hissing and cracking sound that is more prominent on lower levels of volume. It's is driving me mad.
I am using MiUI 12.0.2 and the earphone is a Bluetooth Echobud from Amazon.
I was about to return the earbuds, but decided to try the Echobud on an iPhone X and a Motorola G9 and it worked perfectly.
I am thinking about installing a generic Google OS on the phone is the problem persist. It might be a software problem?
