Extremely low microphone volume during calls

Callers at the other end have difficulty hearing me, and I've never been able to find a solution. At first, I thought it's the ROM I was using, but after flashing the stock rooted ROM, same problem. I'm using the correct baseband. I'll do a test tomorrow, returning the phone to factory condition with the latest images from Google.
Has anybody gotten this problem and was able to fix it?
Update: Back to factory condition. Issue still isn't fixed.
Newer update: Called Google Play Store via this number 1-855-836-3987. They'll be sending a replacement.

Bump. No one else has had this issue?

Bump.. Same issue here.. Stock unrooted

Maybe you can get yours replaced by warranty. I called Google Play Store (that's where I bought mine from) and I'll be receiving a replacement.

While i am not stock, I did notice this one time with my phone... like extremely LOW to the point i was pressing the phone HARD against my ear to hear.
Solution? I went ahead and flashed Paranoid Android 3.56 and flash the Louder volume MOD in the themes and apps section. That fixed my issue, I also know that not all of you will want to root, and that this SUCKS. but try to restart the phone.
Just root guys, this phone was made for that

Oh actually the issue I'm talking about is different. The ear piece volume is fine, but whenever I talk to someone on the phone, they can barely hear me unless I use speaker phone. I was actually using Paranoid Android, and I was being told I can barely be heard. So I flashed back to factory to see if it was a ROM issue. Sadly it wasn't.. On factory ROM I can still barely be heard.

I'm having the same problem as well. Just received my Nexus 4 last week. They especially can't hear me if I'm speaking to them through my car speakers (3.5mm connection, not bluetooth). Wasn't a problem at all in the same vehicle with my Galaxy Nexus. Please let us know if the replacement worked better.

I am also having the same problem...my girl keeps shouting that she can not hear me..at first i thought some problem with network but than some of ma friends said same thing...whats the option now..?? i am from india and i imported it from US so cnt send back there..is anyone found any solution..??
I tried using headsets and the results were pretty much better..

Wish I could help. Just had to RMA mine today. Completely stock, no mic. Works when plugged in, sometimes, but for the most part no audio. When it is plugged in, the wife says I sound like I'm trapped in a bottle lol echo and static.

I had the same problem when I was running full stock. It was really annoying to hear "I can't hear you..." every other sentence.
This won't help if you do not want to root or run custom ROMs but since I switched to PA 3.56 and Matr1x kernel the people on the other end of the line haven't been complaining. I imagine for whatever reason it was fixed would apply to most custom ROMs and Kernels. I'll actually test this out this weekend and edit my post afterwards.
Edit: I made some calls to friends on PA/Matr1x/Radio .48 and everything seemed fine. I flashed full stock and called back the same people and only one person said they heard a noticeable decrease in the quality. That person also knew I was testing different settings on my phone so maybe they were messing with me.

i also switched to custome rom (Carbon) and have not had any complaint regarding the issue..still will confirm in sometime if the problem exist or not

Bumping an old thread ...
So my gf started complaining that she could barely hear me when I was using my Klipsch S4A headphones to talk--while in the car and in a quiet room. I was on CM10.1 at the time and I had read complaints from others with the same/similar issue on other ROMs, even stock/unrooted. I chalked it up to 4.2 and hoped 4.3 would fix it.
It appears that isn't the case. I just sacrificed root so I could flash a clean install of 4.3 (new bootloader and radio included) hoping it would at least mean I could have normal conversations with my gf again while the devs cook up CM10.2. How bummed am I to find out that the issue persists. I just called her from my office with my headset on and she said I "still sound far away." This is really frustrating. I never had this issue on my GNex.

I wish someone comes up with a solution for this.. I was hoping 4.3 would solve this issue also. Some say its cause of the noise reduction, isn't there anyway we could disable noise reduction?! I remembered I had that option on CM10 my i9300 but not on nexus 4 build.. This is really an issue for me since i always use headset for phone calls.. I was wondering if the original Nexus 4 headset would solve this issue.

Hi guys,
i found 2 "solutions" which didnt work for Nexus 4:
1: typing *#*#3646633#*#* into the phone to enter the engineering mode. "Should" work for all Android, does not for Nexus 4
2: the App "MobileUncle". Does only work for MTK Chipsets (Nexus 4 has another one)
my question: is there something like the Engineering mode for the Nexus 4 ?

Same issue on Nexus 5
FYI, the nexus 5 has the low input volume gain when using 3.5mm headphones with inline mics. I don't understand what LGs problem is with 3.5mm connections or why it was never tested.
started a discussion on in here

Any solution yet???
I have the exact same Issue, Android 4.4.2 and the issue is not fixed weird that only Nexus 4 has it. I am like you trying to find an app or a way to work around the issue, tried to install other ROM using rom manager and phone when SLOW as heck so no idea how to fix it yet, loud speaker to every single call is not the way to go

[Q] Nexus 4 front speaker issues

Hello,
This is my first post so sorry if something is done wrong or whatever. Ive been having issues with my front speaker. I dont think i did anything to break it (i drink a lot though) but its been completely useless for the past week or two. I have the latest cm 10.2 and franco kernel nightlies. I thought updating them might help but it didnt. I also can no longer talk to people on speakerphone like i could before (while the speaker still didnt work). I also tried headphones and now they dont with either. Does anyone have any idea what it could be and/or different ways to fix the speaker?
Thanks in advanced!

I havent used the stock rom since january and no i did not have this issue. Its been a recent thing

Phone Speaker crackling, noise, static, while screen off. (Also on call)

Easy to test, go to a very quiet room. Really quiet. Put your phone to your ear while screen off and listen. (Not phone off)
You will hear a faint sound, static, cracking well some kind of noise.
This is nothing new, and not just bound to this phone. However I had this issues only on the Nexus 4 and never noticed it on other phones I had.
It becomes a bit annoying while in call, really quiet room, and every pause, when both parties are not talking.
I think only option is learn to live with it? As if the numerous threads from N4 and other devices are true, this is a HW fault on all devices. Some ppl just do not hear it. What varies is the intensity, which ppl reported that exchanged their devices.
Is there someone on some variant not hearing it? (State your age as well)
Is there someone who exchanged their device based on this problem and got a new one with a different level of the noise?
Mine is international LG D802

I do hear the pops and squeals when I'm on a call, but not otherwise. VZW version, rooted, stock rom, "A" version of modem/radio.

The sound that you experience, since its through your BT as well, might be normal connection/call sounds. I have this really on all phones even sometimes on iPhone. But if its something tha tyou do not expect to hear, and have it constantly , bring it for repairs, I do not have somehting out of the ordinary in the calls, except what I described in the OP.
What I mean its really like static electricity, cracking sounds. But its faint, you won't notice it in normal environment, at least not when you do not know what to look for. There are youtube videos for the N4 with the sound I mean. cant listen to it now, as I am at work but I think something like this http://www.youtube.com/watch?v=9wOxtzStUZ4
you really need a quiet environment, put your ear to the earpiece.
Also thanks for your post!

I am on ATT and noticed this and I was thinking about returning it but I tested the display model at the ATT store and the same thing. I tested an Iphone 4s and the same thing with the earpiece. I think this is more common than people think because you really have to be in a quiet setting to actually hear it. Thanks

FWIW, I haven't had this issue at all since the update came out months ago. Maybe they just haven't updated the demo model in the store.

Thanks for the info are you saying you had the issue prior to KitKat and the OTA with KitKat resolved the problem

All I did was accept the 12B update. 24A (Kit Kat) is rolling out now, I believe.

I'm sorry for bringing this from dead, but have you guys found any solution for this? Or it's not fixable once it occurs? charging + headphones +v4a developed this bug this evening on my g2.

My ears or better brain adjusted... same way you adjust to every annoying sound after a while. It is there... but you stop caring - hearing it.
I do not believe there is a software fix. If your problem is the one that I described, new hw might help.
But as I said. I adjusted ...

Definitely seems to be hardware problem. If I knew about it earlier I would never connect headphones and charger at the same time. Symptoms: static noise @ approx. 120bpm from both speakers, while phone in deep sleep.
Tried uninstalling v4a drivers, app, poweramp, flashing different kernels, clearing caches, and what so not.
I don't want to raise hope, but I found temporary workaround. I'm on stock kk, and I use g2 tweaksbox and gravitybox to get statusbar aosp quicksetting tiles. There is a compass tile. If I leave it ON there is no more noise. At first I thought that maybe this prevents phone from deep sleeping, but bbs is showing that phone sleeps well. Have not tested standby battery impact yet.

Hi,
Thanks for the remainder, as I noticed latest @dorimanx kernel eliminates this (from v 8) and my itchy fingers installed Viper4Android again and yes I struck my luck the distortion starts again...
My conclusion is an option between have better audio performance in mid to high volume level. But, lived my days with G2 enjoying the distort...
Or uninstall everything about viper4android and listen to flat music beat...
And I choose ingore the distort and drive away with awesome audio performance in my bluetooth car audio....
Cheers,

Hey, do you have xposed? I noticed that if I enable compass in quicktiles, there will be no more crackling. But I'm not sure about battery. So I use this when it's quite, in the evening, and I start hearing cracks, I just turn on compass.

[Q] Noise cancellation sounds terrible

Just after getting my G2 i installed CyanogenMod 10.2 Milestone on it. I started doing some tests to see if CM could be my daily driver, and nothing really seemed to be a deal breaker, except, when i try to record videos (or I'm guessing any other sound recorder) the sound it not really that great. I went back to the stock LG software, and was hoping i only had to stay there until CM fixed the noise cancellation issue. But what do i find, the noise cancellation problem is still there.
I have been looking around here on the XDA forums, (This is my first post btw) and I came across this (what seemed like) amazing mod. http://forum.xda-developers.com/showthread.php?t=2471900 But it might just be me being a droid-noob (Have only had android for 2 weeks now), but i cant figure out how to get this to work, it even bumps up the quality of pictures and videos including other cool tweaks. I have tried installing the .zip file via CWM, but that gave me nothing, also tried installing the cameraapp.apk the thread provided, but it just refused to install.
So please, if any droid-guru can help me make my microphone sound better, (both in the stock software and in CM) i would appreciate it!

Are you using some cover on the G2 ? If so, try removing it as it might cause disturbance to the reference microphone.

I do not have a cover or case, and I know the noise cancellation is software related. My phone is the D802, the one without a rear-facing microphone, maby that can have something to do with it?

I have the same problem witm my lg g2.After I record a video or use voice recorder the sound freezing and the quality is very poor.I thought that I have only my this problem...My phone is not rooted and I have it from yesterday morning.Today I sow this problem.I made a factory reset and the problem is not solved.Is something that I can do with this issue?

I have thought about that, but I've heard a few other people have this problem as well, and im 99% sure it is software related. Though to every rule there is an exception..

Just some more info. Here is a video i recorded going home from work, and as you can hear the sounds are very "Watery" or "Distorted" as many describe it. (The bad video quality is a combination of my using CM10.2, only recording in 720P and YouTubes bitrate being bad as always)
http://www.youtube.com/watch?v=mgdtWzoQkOU&feature=youtu.be
And no, I did NOT cover up any of the microphones, im 100% sure about that.

Video uses the rear mic for audio zoom. Not even sure if it cancels as well like the top. Verizons model ONLY has a top. I have no distortion or watery sound when using stock recorder or on video. I however do get dead silence between some sounds, very good cancellation, sometimes a bit too much. Voice Privacy in dailer has NOTHING to do with voice cancellation. It is an algorithm used to encrypt voice communications and is worthless being hacked long ago. VS980

I have the d802, and that does not have rear mounted microphone. So maybe it is just some bad optimization. There has got to be a way to disable the noise cancelling microphone, or use it as a secondary mic.
Sent from my LG-D802 using Tapatalk

Okay..
So basically every rom out there for the G2 has terrible sound when it comes to the microphone, but there is a fix, i'm sure!
A few weeks back i downloaded the AOSPA 4 rom for the G2 and installed it, and guess what, it removed the noise cancellation!
But after the rom was buggy here and there, I decided to live with the bad sound on CM 10.2.
Now a few weeks has gone by, and I wanted to try out the updated AOSPA 4 rom, but what is diz, the sound is terrible!?
So it seems like the whoever is in charge of the AOSPA rom for the G2 has brought back the horrible sound.
Now is there a way to get the microphone profiles from one rom over to another? I have the old AOSPA 4 rom, with the working sound on my computer, and I want to take the microphone profile, and save it, so that i can manually add it to any other rom i download in the future, because I know that roms like CM probably wont update the mic profile for one specific phone.

Hey there, I just got myself LG G2 D802 and I find the noise cancellation in videos to be extremely annoying. Do you guys know if there is a fix to it yet? Something to disable it would be awesome.

Might be a HW fault or y'all are being too sensitive videos recorded with my D802 have great sound.

Cyanogenmod - Bottom mic not working on any version?

Hey guys, recently just picked up an S4 from a friend after my HTC One battery kicked it. I have a random problem with the phone that I'm hoping someone here can help with.
When using a stock or TouchWiz ROM, I have zero problems with both the top and bottom microphones. I can speak to people in calls or record voice using apps and it's loud and clear. When I install a Cyanogenmod of any version (I have tried 10, 11, 12, 12.1, and 13) the bottom mic drops it and becomes very muffled to the point where you can't hear anything on the other end or in a recording. Speaking in to the top mic works perfectly though. Bluetooth works fine too and I have no issue speaking to or using A2DP with it.
Has anyone seen this before, and if so, has anyone fixed this? I'd much rather use a Cyanogenmod ROM instead of TouchWiz but at the moment it seems I have no choice ...

Try other roms. CM based or AOSP roms.

Try a rom that has alucard kernel (either flash optimized cm12.1 or jdc team aosp) and go into stweaks and in the sound tab change the microphone gain sliders.

I now have CM12.1 with Alucard kernel and STweaks. I've turned the Camera Mic Gain up to 60 and people can hear me now, but they say it sounds slightly quiet still. Is there anyway to go past the max setting in the STweaks?

Not that I know of.

Are you sure you don't got dust in the two holes? Sound to me you have to clean the two holes.

Nope, I had the phone apart and cleaned both holes, no difference.
The confusing part is that on a TouchWiz ROM the microphones work as they should. It's not until I'm running CM or AOSP that I get this problem.
It's almost as if the microphones have been switched and the top becomes the voice mic and the bottom becomes the noise cancelling one.

I've lost count of how many times I've pointed out this problem. No, changing gain value will not solve the problem. This has been a truly dealbreaker for me, as this affects every cm based rom. @AntaresOne said that this problem comes from using caf drivers and I think it cannot be fixed unless Samsung releases its own source codes.

Nope, I had the phone apart and cleaned both holes, no difference.
The confusing part is that on a TouchWiz ROM the microphones work as they should. It's not until I'm running CM or AOSP that I get this problem.
It's almost as if the microphones have been switched and the top becomes the voice mic and the bottom becomes the noise cancelling one.

It's strange because on my I9505 I never experienced this problem.
What bootloader and modem are you running?

Well that is crap ... I guess I'll have to go back to TouchWiz which is a damn shame. Have you had any success with AOSP ROMs?

They are all in the same boat. To solve all problems you have to stay with TouchWiz ROMs

I find it hard to believe that I never had those problems with my I9505 yet you have them. What's your modem and bootloader version?

It's not that hard to believe, seeing as there are over 40 different S4 models. You just can't make a rom to work perfectly on all.
I never had any major problems with any of the roms I flashed, yet other people seemed to have serious issues with the same rom.
I don't know why Samsung can't make just one model. It splits the user base, it gives them more headaches because of updates and such.

Yes, I agree on that. It's crazy to make that many models. I made the assumption that he has an i9505 but maybe he has a different model.

Try to record a voice message with Whatsapp using TW/GE rom and then with CM/AOSP rom, you will clearly hear the difference. jfltexx here.

Yes, I've tried AOSP roms but no differences. AOSP based roms for S4 share some sources with CM.

Bootloader/baseband is I9505XXUGNG2
Going to try updating to the latest baseband soon and see if that has any effect.
Pain in the ass but see how we go!

Update bootloader and modem to Lollipop. Update both not only the modem.
