Microphone issue ( Maybe Noise Cancelling) - Zenfone 5 Q&A, Help & Troubleshooting

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

Hissing background noise when recording video

Hi,
Just got my new xperia arc and whilst it is a great phone I've found that there is a loud hissing noise (like rain) when recording video. I've uploaded a video to show the problem. Ah, just tried to post the link but I've been told I can't as I'm newly registered...
Others I've messaged have the same problem but there doesn't seem to be a fix. Are there any suggestions as this really kills the HD video function for me...
yeah I have the same problem, I think it got slightly improved with the updates.
try updating.
The phone is upated to the latest firmware t-mobile have to offer. I guess the only other option is to debrand and install generic firmware?
my phone is debranded, I tried uk, Global and Hong Kong, they're all the same.
So why isn't this problem more widely reported then? It pretty much kills the video recording capabilities.
I've experienced that too.
Try not to obstruct the first microphone with your right hand, the first microphone is at the bottom of the phone. Check if that solves the issue
It doesn't solve the issue, my fingers are nowhere near either mic hole.
I've also tried some test videos where I cover up each of the mic holes with my finger. I've tried covering up mic 1, mic 2 and then both. Now, strangely, when covering up the mic my voice does get a little muffled but the crackling/hiss does not change.
This indicates to me that this is a possible software issue i.e. compression of the audio or the way it is recorded, rather than the mics physically picking up the hissing.
If the mics were picking up this hissing (i.e. too sensitive etc) then covering up the mic hole would give some change, which it doesn't.

Low microphone volume?

Does anyone else have the person they are talking to mention how low you sound to them when speaking on the phone?
It seems like I have a low microphone on my nexus 4, unless the phone is directly in front of my mouth the person can't hear me clearly, I'm thinking it might be hardware but I know with some phones this can be corrected with a custom driver that makes the microphone more receptive
Is there an app or setting that I can use that would disable noise cancellation in case that's what causing my mic to make me sound low?

Actually I have the exact same problem - not sure what we can do to fix it.
If I crank up the volume fully it appears to -sometimes- solve the low audio problem.

if it -sometimes- solves the problem then it might be a software bug. i hope some dev can be notified of this. have you tried a different ROM? if yes, have you notified the dev of the ROM?

Its actually on stock, so I just rooted it, and will try with a different rom shortly.
Same thing here.. Sometimes they hear me, sometimes they don't even during the same call..
I'm starting to think the noise cancellation is playing some tricks.
While driving home this afternoon I was on headset on the freeway, where those I talked to could barely hear me.
Unplugged my headset (klipsch s4 image ii), and sound was good. After a while I plugged headset in again, still bad.
When coming off the freeway I kept the headset on while talking - and all of the sudden it was crystal clear (using the words of the guy I talked to at the time). At the same time I noticed that I had no data (outside even edge coverage), don't know if that is related or not.
Is there some way we could experiment / disable or tweak the noise cancelling?
Ps: I have had the same issues without headset also, so definitely something general software things going on

I had the same setup. I am using the Xylon (stable) 15 ROM for several days now, and SO FAR I think the microphone reception is better. I haven't heard complaint from the person I speak to on the regular. *cross fingers* hope it's 'fixed' in some way.

That's exactly how my phone was as well. I would be on one call for a while and all of a sudden out of nowhere the person I'm speaking to says I sound like I'm speaking across a room and I'm like 'wtf happened? I haven't changed positions since I started talking to you!'
I did a little testing with the person I was speaking to as well, to test the microphone receptiveness and the mic seems to pickup my voice better, I wasn't speaking directly into the mic and they said they heard me fine.

I have a sneaking suspicion It might have to do with the noise cancelation as well, I think on paper whoever designed that feature on the phone thought it would be cool but it doesn't seem to be panning out too well. I've read somewhere on this forum about how to increase microphone volume and cancel the noise cancellation using the Terminal Emulator app and/or the phone's dial codes (#*#*some sumbers*#*#).
I have the same earphones (no mic attached) and I have similar experience but I haven't taken note of it like you have since 95% of the time I have my headphones in the phone.
I also want to mention a little trick that I think seems to work when on calls. Whenever I turn the phone over, screen facing opposite of me, I hear less complaints of me sounding too low to the other person. Maybe it's doning something... i dont know.
Same issue - with headset only though
I have the same issue, people really struggle to hear me on conference calls (which I spend a lot of time on), so I have to hold the mic in front of my mouth to speak which gives awful sound quality. I don't have this issue when not using a headset (phone mic works fine).
Nexus 4 + Klipsch s4a = really quiet mic, people can't hear me at all.
Nexus 4 = No problem, phone mic works.
Note - music playback is fine, no issues there.
My klipsch headphones worked fine on my GNex, no issues, so I don't think it is a problem with them. It has been an issue from the moment I switched to a Nexus 4. Have also tried other headset (samsung one that came with Gnex) - and have the same issue of sounding very quiet on the headset mic.
I did wonder if it was an OMTP vs CTIA issue, but the button on my headset works fine to answer/hangup/skip tracks/open voice search etc. so I don't think it is that.
I also tested with another Nexus 4 handset using Soundmeter and got very similar results on both handsets, suggesting it isn't a handset issue (though not a very scientific test).
Does anyone have any ideas?
Just In Phone Calls?
Hi Folks,
Is this mic issue just related to phone calls?
I'm using the latest CM10.1 nightly build and my mic is useless for phone calls.
However, Google's voice search works just fine and if I record a video my voice is recorded just fine.
I could be wrong but I suspect the Nexus4 can not use the phone jack for incoming audio.
In my opinion when one plugs a headset into the audio jack the Nexus4 camera microphone
becomes activated, not the headset one. And the Nexus4 cam mic is really bad.
Again, I might be completely wrong. (I hope)

OMG you have it reversed. What a mess!
I have yet to see Google Search understand anything I say and video sound is horrible. Call audio is great.
Hi guys - I am on stock android - same issue on 4.2.2 as on 4.2.1.
This isn't just related to phone calls, same issue on google search. I tested headset mic pickup volume when speaking normally with Soundmeter - around 35-40dB (what it calls a quiet whisper at 3ft to quiet residential area, Park).
I also tried moving the headset mic closer and further away from my mouth with the phone in the same position - with the headset mic virtually touching my lips it went to about 60 dB (normal conversation at 3ft) - so it does seem to be related to the headset mic. I can only guess it is either a dodgy connection in the handset or some noise cancelling functionality that is cancelling out my voice!
Any ideas or thoughts greatly appreciated

Darn it!
I knew I was an outlier.
No way I'm getting a fix for my issue then
Anyone figure out a fix? I'm having similar issues with my microphone.
Hooked as bluetooth device in my vehicle, other end hears me fine.
On phone call using speaker phone, other end hears me fine.
On phone call WITHOUT speaker phone, other end cannot hear me at all.
Using a sound recording app to record voice, playback of the recording I can hear my voice faintly if I was YELLING during the recording.
Shazam/Soundhound apps do not work.
I am rooted on rasbeanjelly/trinity kernel. I have to say this issue started a few days ago when I have done no changes to the phone. Already running the rom/kernel for weeks.
I've tried flashing back to stock rom/kernel and the same problems persist.
Any ideas?

Just an update, I unrooted and reverted back to stock and the problem went away, so it was defnitely a software issue. Will be trying other roms/radios/kernels and see if the problem comes back.
I was on rasbeanjelly 4.2.2/trinity
akira112, did you get any success with your experiments?
Guys, is there any progress / comments regarding this issue?.. Microphone itself works fine when recording the voice with some app, but during the voice calls it is the mess...
My Nexus 4 is two months old and is being returned to Google due to the microphone constantly cutting me out on calls to business clients. I've tried every trick from sound apps to custom roms. No joy. I'm hoping my replacement doesn't have the same problem (although given the sheer number of postings on this issue, I suspect a Nexus 4 design flaw)...
Hello
Is there any solution to low microphone volume problem?
I have been using my N4 for a week and some people complain about my voice's volume. There was no such problem with my previous phone (Defy). There is no difference whether I use phone's mic or bluetooth headset.
My Nexus runs CM10.1 with Franco kernel.
Also keen for a solution
I just returned my first N4 due to the speakerphone cutting out after a minute or two, and getting stuck in non-speakerphone mode.
The replacement seems to not have this issue, which is nice.
But now people are telling me they can hardly hear me. It happens both with normal mode and speakerphone mode.
Ridiculous.
I will be calling Google tomorrow to see what they say, but I am not going to hold my breath for a decent response. Judging by the number of people reporting this issue online, it's not something Google has a solution for.
If anyone figures this out, I'd love to hear about it.
Have sent mine for repair because of this problem. People told they could not here me well.

I have the same issue, couldn't fix it but what I noted was that any mic gain adjustments I made only applied to the phone's mic not the headset mic. That means that there is something else that modifies the headset mic, but I do not know.

Microphone does not work only in speakerphone mode

Hi all,
I just got a Nexus 4 recently and I've been racking my brain with what on earth is happening with the microphone.
The problem is that the microphone WORKS PERFECTLY when doing a google search, voice call in normal mode, or voice recording. It does not work at all if I enable the speakerphone during a voice call. This seems to be exactly the opposite problem that others are having with the Nexus 4. I can still hear the person in the call but when I talk, they can't hear me. Not even white noise, just total and utter silence.
I have tried 2 flex cables (trying replaced the initial one whose microphone didn't work at all, at the time I had CM11) and tried flashing everything (baseband, recovery, system) to stock 4.2.2, tested it with no luck. I then flashed everything with the latest version 4.4 off google's developer section and tested with the same issues. I've tried factory resets, unplugging the headphones, and also soundabout and nothing resolves the issue.
When I look at the flex cable and the phone housing, it seems to me that there is only one microphone on the bottom. On the top, there is the noise canceling mic, but I don't think this has anything to do with the speakerphone. Am I wrong? Does anyone have any thoughts or suggestions? I don't know whether this is a hardware problem or some low level software issue.
UPDATE:
I noticed something super strange. If I plug a headphones w/ a mic into the headphone jack, I can actually hear very loudly and in great detail the friction from my fingers moving up and down anywhere the case of the phone, and if I tap on the body of the phone (anywhere, even near the USB port on the bottom) it's like stuffing paper into your ear canals. I can still hear the person on the other end fine, and they can also hear just as clear and loud when I touch the phone body. This phone is a science experiment now. The closer I move my fingers to the bottom of the phone near the mic, the louder it gets.
've tried everything. You also changed the Kernel, I do not know ... Maybe it's a problem RADIO, but I doubt it.
Eventually contact Google support
Typical factory problem....when i bought my Nexus 4 (S/N shows production date is October 2013 so its the newer batch with little nipples and camera lens offset fix) the microphone was dead and i could've only talk through headphones and speakerphone....took it to the repair shop and everything works now. Don't know what they replaced, maybe it wasnt the microphone.

[Question] Microphone Issues - Any ideas?

Hello everyone, I've checked the forums and I've not really seen many answers to this question as it's something that's been bugging me for a while now.
I don't know when it started, but I noticed recently after recording a video and playing back, the sound on one side is completely gone. Almost like Stereo mode has been disabled, I have determined that it is the microphone that is often used during Loudspeaker calls, I tested this by placing a call to a friend on a regular call, then a WhatsApp Call, and finally a Skype call - and each platform is having the same issue - my loudspeaker microphone is not picking up audio. Is there a fix for this? I took apart the device, cleaned thoroughly but I'm wondering if the microphone itself has become busted. If anyone has a similar issue, or has found a fix for this - could you please provide me with some information? I love my Note 3 and would love to start recording some videos again.
Thanks everyone!

First factory reset and check again. .if same it s material problem
I've Factory Reset about 10 times since this post, and attempted all kinds of different things. I can confirm that it is a definitely a hardware issue, could you recommend what to do so I can get this fixed? Again, my primary microphone works fine while making calls - it is only when I enable Loudspeaker that the other party is unable to hear me due to the "Top Microphone" on the device not working for some unknown reason. Again, I've attempted cleans, fixes etc - but the issue only occurs during loudspeaker calls and when recording video as the top microphone is used with the primary microphone for Stereo Recording.
I know the microphone still picks up some form of audio but at a very low level - as I have called a friend and enabled loudspeaker and continued on to blowing in the hole where the microphone is situated. They can hear the loud distortion created by the air, but not a voice or anything like that. I really have to shout (And I mean LOUD) if anything audio is to be picked up.

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
