I have noticed an issue that did not exist with the Galaxy Nexus.
When not on speakerphone the microphone sensitivity is down-regulated significantly from the way it is when it is on speakerphone.
Frequently people connect the phone via auxiliary cable in the car (as a hands-free approach), but in order for it to route the audio to the speakers for the car, it cannot be on speakerphone. However when not on speakerphone the sensitivity of the microphone is limited, it is not the same as on speakerphone, therefore unless you have the phone right beside your mouth, the other party will be unable to hear you (due to low volume).
I assume this is an software change in 4.2, I have tested the issue on two Nexus 4's. When turning back on speakerphone, the microphone increases sensitivity again, and the other party is able to hear clearly again.
This poses a problem if you want to have the phone in your car connected to auxiliary and not right beside your mouth/face. I assume they added this because they assume that if the phone was not on speakerphone then it would be right beside your mouth/face during a call, however this is not at all always the case, especially if you connect your phone via aux in the car.
Anybody else experienced this? Any work-around?
Yes, thats really a shame.
I think, it is the noise cancellation. Nexus One has Niose Cancellation, too.
There I've found out, that I have to make a change in the build.prop to disable this
but I really don't know, where to find the line in build.prop to disable the noise cancellation.
And: You have to root your phone to do this.
It's really a shame, I can't use my Nexus 4 in my car plugged into the auxiliary input
hmm anyone can disable it via build.prop?
reminds me a of the days in Nexus one..
I've opened an issue on Google.
Hoping for many votes, that they can see it.

Thank you so much for bringing this up. This is my main beef with the phone coming from my Gnex. Hopefully a fix can be found soon.:good:
My suspicion is that this has to do with noise cancellation. The way noise cancellation works is that there are two different microphones at opposite ends of the phone; the one farther away from your mouth picks up ambient sounds and, more faintly, your voice. The one nearer your mouth picks up ambient sounds and, more loudly, your voice. What gets sent over the phone connection is, effectively, the difference between the signals from the two microphones, leaving mostly your voice.
If the two microphones are roughly equal distances from your mouth, they both pick up your voice about equally strongly, meaning that your voice is mostly filtered out with the rest of the ambient noise. Speakerphone mode disables the noise cancellation, so your voice comes through strongly.
.... as I've said in the second post. Other phones don't have trouble with it.

Exactly. This is not simply a noise cancellation problem IMO. Other phones have noise cancellation too but don't have this problem.

Sorry for inadvertently repeating what you said in that post; it's been nearly two weeks since then, and I had forgotten it had been previously mentioned.
Perhaps the other phones with noise cancellation that don't exhibit this behavior simply turn it off if a headphone is plugged in. That would make sense for a speaker-only headphone, but not necessarily for a headphone with an inline microphone, where the voice microphone would still be nearer to you than the auxiliary microphone. If that's the case, it would be nice if that setting were exposed as a controllable option.
Please look here and add as many stars, as you all can:
http://code.google.com/p/android/is... 4&colspec=ID Type Status Owner Summary Stars
I'm the only one who has told it to google and with one star I think no one will see this problem there.
So we have to gewt as many stars and comments as possible.
Any developers can help with the build.prop line to disable this?
I remember pm founder of cyanogen mod and he pointed me the line to disable in nexus one..
I heard if you get an external mic it is much better but I haven't tried myself. This is annoying because I usually just use the aux with my nexus s with no problems >.< Anyone out there got any other solutions?
Yea seriously bump on this topic. This is a massive problem..

It's the other party not being able to hear when on aux.
Misread.. But Yea if using speakerphone to avoid this problem ull barely be able to hear them, simply not loud enough
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.

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

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.
When I bought the device 2,5 months ago I had no issues at all, but a few weeks ago I started noticing a lot of white noise when listening to music through the headphone jack on my Note 4, especially the right headphone. I have the feeling the issue started when I updated to NK4, but I'm not sure, so I don't want to downgrade just yet, since I have a lot of app data and it's quite a hassle to make a back up.
I was wondering if anyone else experiences this issue. I know it's present on some Nexus 5 and LG G3 devices as well. I have taken it to the Samsung store and they tried with their headphones as well and the issue persists. It gets even worse when I'm in the car using an aux cable to my car radio. Every time I accelerate or decelerate I hear a howling noise. Also when I'm just using the phone, not listening to any audio at all, all system sounds and notification sounds turned off, I often hear a clicking sound. At first I thought the back cover was a bit loose and made this sound, but it's actually coming from the speaker.
The issue is present in several apps: Youtube, TuneIn, MP3 Player and Google Play Music.
Is there anyone else who experiences such issues, because I'd rather not bring my phone in for repairs, as here in Holland that might take 2 to 6 weeks? And does anyone know if it is a software or a hardware issue, if anyone has found that downgrading might be a fix, I'd be happy to try that.
Ok..maybe I just got a bad unit. But here it is. Phone is one day old.
When I initiate a phone call with my wired headset, I immediately get hissing. Then if I move my head or the wire brushes my cheek.. it sounds like someone is making sexy time with a paper sack inside my head. This isn't an echo as it is real-time. All the noise is obviously being picked up by the mic and is pumped into my ears at an explosive level. I attempted to turn the volume down which only resulted in the call volume dropping rather than the demonic feedback. It kind of reminds me of the in-ear monitors that vocalists would use.
Here's what I've tried:
1) 6 different headsets, all different brands and cost including the freebies that came with the phone. The only set that didn't blow my eardrums out with noise were some cheap ass Maxwells from Wal-Mart, but the problem was still there
2) looked through all the settings I could find. The only thing that makes a difference is turning on TTY mode.. which causes too low a volume for me to carry a conversation without going into a noise cancelling chamber.
3) applied the latest OTA update. No change
What I'm willing to try:
1) rooting and flashing a new rom.. But only if this will actually fix my issue.
2) perform a sacrificial ritual involving an SII, an SIII, and an S4... None of which had this issue.
3) changing some call setting that is hidden somewhere between Narnia and Atlantis....
Thanks in advance
Quick update....
Tried the demo unit at retail store.. same thing.
Tried bluetooth headset.. no problem.
It seems like as soon as the Phone app opens a connection the mic is overamplified or SOMETHING. It is driving me nuts and I hate my BT headset.
Still wanting to know if anyone else is experiencing this.
Just a quick update.. This is still present even with BT headset. For a lack of better phrasing.. this seems like the mic is being back-fed into the ear pieces. And it only happens on the Phone app. It there a setting somewhere that I am missing that will solve this? It is super annoying to be able to hear yourself and surrounding noises than the person you are trying to talk to.
Thanks
Tried mucking around in mixer_gains.xml to no avail. Maybe some kind soul who is smarter than I am could provide some guidance? I don't know how to explain it any better.. It's as if everything going into the mic is being output simultaneously to the buds. It drives me nuts
I just tried to listen to what you were describing on my headsets/headphones but I couldn't replicate it. Crystal clear calls for me, and apart from it being the headsets I have no idea. Maybe both you and the store have faulty units.
Hi guys, I have a request for you guys. I hear a static noise in my left ear bud when I plug it in to my nexus 6p. I don't hear it on two front speakers on physical body of the phone just when I plug it in. I hear it through my ear buds. Can anyone confirm if this is a software issue or just me?
The static volume is very low so you might want to be in somewhere quiet area(library quiet)
I don't hear anything in home screen though just when I'm on some app such as twitter or YouTube or Facebook.
I'm going to try with different earbuds and headsets see if all do it too.
I know Samsung tablet (tab pro 8.4) had similar issues as well so I'm suspecting software. And I'm hoping it is software bug.
Thanks guys! This phone is great by the way. Loving the display and heptic vibrations.
Yeah, sounds like software. What app are you using? Have you tried another app? Any kinks or damage to the cable of your headphones?
No, I just purchased this JBL earbuds and didn't have any issues with other devices. Also it seems like consistent with other headsets i have. I know for fact it isn't my headsets and earbuds issue. That just boils down to either hardware issue or software issue. I'm just hoping it's a software.

I'm not blaming on this device just yet. I've had similar issues with Samsung Galaxy Tab Pro 8.4 with static noise. And all confirmed that owners do experience the same. But Tab Pro was actually on physical speaker. So I'm most certain its just the software.
As far as other issues other users posted, I have none. Except this static on 3.5mm port.

I got JBL J22A from Newegg when they had on sales for $8. Supposedly retailed at $50. Sound quality is very good for $8. Not too heavy bass but deep. Mid tone and vocal tone are very easy to hear as well. The most important part was that noise doesn't leak through the ear when you put them on, outside noise is isolated as well. Clear sound all around.
I'm not experiencing any static with headphones plugged in. Using a Razor gaming headset.
I listened to Spotify for about an hour while I was at the gym earlier. No static whatsoever. Sound was perfectly fine.
Used a pair of Xiaomi Piston 3's.

Well the noise stops when music or sound is playing. It starts to have very low static when there is no sound. And gym can be very loud, the noise can be heard very quietly. Thanks for the feedback.
I can confirm that I am also having this issue with my Bose QC20s. Goes away when audio is being played. Also seems to only occur when processes are running. Try going to the home screen and opening and closing the app drawer. Does that cause the sound for you as well?
Wanted to provide a quick update. I went and tried a pair of QC20i and they do not have the static issue. Since these are made for Apple products and have the three button remote the 3.5mm jack is a little longer. The previous set I had only had a one button remote. Probably not an easy fix for everyone but wanted to pass this along.

Yes, your symptoms are exactly same as mine. I've also tried headsets without microphones and no static, the one with microphone seems to have that noise. so maybe it is some sort of design flaw.

The QC20i have a microphone and no static. My hypothesis is that the larger 3.5mm headphone jack on Apple certified accessories (or those with 3 button remotes) work fine.

damn, my JBL makes static but i can deal with it because it is so tiny static. all my other junk earbuds (generics) have no statics at all. and i don't want to carry around my sennheiser headset around, so big.
at least it is okay with sound. thanks for everything.
dont worry, I have static noise on my 3000$ macbook pro retina...
I have the exact same issue with mine. Static noise, but only when no audio is playing and I'm in an app (doesn't happen on the home screen). But I've tried two sets of headphones: the one I have with a mic gives me the static noise, the one without does not.
Very weird.
Same problem with my Bose QC20 too. I thought I had a defective 6P, but looks like jack issue. It's an annoyance, but learning to live with it since this is otherwise a great phone.
I have the apple earpods and whenever I use it to talk if something rubs against the microphone (my shirt/jacket) in the headphones it makes the static sound. It it's not touching anything nothing happens. When I rub my finger over the microphone/volume buttons it makes the static sound.
