I noticed that when I was playing with Snapchat and was trying to record music from my earbuds that the best place to hold my earbud was next to the hole on the back of the phone and that when I held the earbud next to the speaker on the front (specifically the bottom one) the audio from the headphones was almost inaudible. This seemed pretty weird to me since when I talk to people it's usually into the bottom part of my screen and not the back of the phone... Regardless, when I switched to the mic on the back it was equivalent to hearing the music directly from the earbuds. Any reason for this?
My microphone wasn't working that well..everybody I talked to on the phone said I sounded muffled . I got a replacement today. You have to notify project Fi
It's a common problem, RMA won't fix it as it is a software issue.
It happens because of noise-cancellation being set to too aggressive. You can't change it without root, so we'll just have to wait for Google to fix it via patch.

OK everything been fine with my phone until this evening. My phone comes from the 2 week delivery estimate from the Nov. 27/2012 order batch
I needed to look for a local restaurant. Pressed the mic on google search bar and it would not recognize that I was talking. Tried a few times. Then reset the phone. Tried again. Turn the phone off and on. Tried again. Downloaded a voice recorder. It recorded static but no voice at all. Downloaded sound meter. It flux between 20-30db. I then called my wife. She couldn't hear me. Switched to speaker phone and she could hear me just fine. So now I reset my phone to factory and same results.
Any ideas? I know it worked earlier because I used voice recognition to send some texts without problems. I visually checked the mic hole in case lint or smeg might have blocked it. But it's clean. Blew into it just in case too. The top noise cacellation mic seems to work picking up ambient noises according to the gray rings around the google search mic icon. But it doesn't light up red.
Same issue. I used to be able to make it work better by plugging a cable in the charging port. Now nothing.
Does anyone know if there is a way to set sensitivity of the mic? I am assuming the same mic is used for speaker phone as with every other app including phone.. Since speakerphone seems to work..
So I decided not to waste any more time and get the RMA process going before I am outta my 15 day return period.
Was quick and easy. Exchange will arrive with in 3-5 days. Return label was in my email before I hung up.
on the iphone 4s and the gs2... speakerphone uses different mic. i could be wrong, but the reason i say this is... in my iphone.. i got sand on/in my phone and was blowing it out with air compressor. i ended up dislodging the bottom mic and had to use speaker. then on gs2 the leaked roms, specifically showstock... needed noise reduction turned off in order to use bottom mic. had something to do with the 'mic swap' from international to att version. but the end game was... i had to use speaker.
as far as maybe getting it back in shape before your rma arrives... did a piece of lint or something get lodged in the mic hole?

Running a sound tester app or recording, initially it gets sound, but it seems to be static. It looks like what you are talking about with the gs2, the noise suppression kicks in and stays that way.
I really wish I could troubleshoot it before having to send it back, just to know what caused it and not repeat it on the replacement..
I looked at the bottom mic again, looked like a grain of sand. Got it out but still same results.
Does anyone else have the problem where the other person can't hear you when you use a pair of headphones while in a call? When removed, they can hear me fine. I'm hoping that this is a software issue that can be resolved in an update. If not, then i want to return it before my remorse period is over.
I am having distorted sound - other party hearing it unclear and distorted..
looks like a hardware issue.. tried with 2 earpiece... no luck.
I'm actually starting to wonder about that. It may actually be a software/driver issue. I was on the phone yesterday and decided to do some testing. Unplugging them and plugging them back in provides perfect audio to the other person for a few seconds before going back to garbage, as does muting and then un-muting the microphone when in a call. Something I've noticed about the microphone is that the gain seems to be set too high - try to make a recording of cars going by - guaranteed clipping (don't have the volume too loud or you could blow out the speaker you're listening to it on).

I ran into the same issue. However, the headphones I was using didn't have a built in microphone. I discovered that if I plug in headphones that lacked a built-in mic, the phone switches its internal microphone's gain to the gain it would use if you were holding the headset to your ear. I held the microphone in close proximity to my mouth and that solved the issue.
I guess this would be a software issue.

That's exactly the testing I did and exactly what I was thinking. Now to wait for LG or Google to fix it.
Another experiment you might try would be to put your finger over the secondary microphone on top of the phone and see if that makes a difference. (My guess is that the reason your voice comes through softly with the headphone plugged in is that the phone is still doing background noise suppression, which works by taking the difference between the main microphone, which picks up your voice plus ambient noise, and the secondary microphone, which mostly picks up just the ambient noise. When your mouth is far away from the phone, your voice is equally loud in both microphones, so the difference doesn't yield much voice signal. If your voice comes through louder after stopping up the secondary microphone, that would confirm this explanation for the problem.)

Next time I'm in a long phone call where I am using headphones, I'm going to try that. It could be possible.

This appears to be what is happening. The top mic is doing noise cancelation for the bottom mic.
I called a friend and plugged in headphones. When I didn't cover either mic, she said I was quiet (because the phone thought I was background noise). When I covered the top mic, she could hear me fine.
At this point, I'm inclined to say this is a software issue because the phone app can switch between microphones and which one is used for background noise cancelation. (Putting the device in speaker mode appears to use the top mic only.)

That's good confirmation -- thanks for running the experiment. Maybe I'll put a little wad of putty in the car to stick over the top microphone while I'm driving!
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.
I am familiar with how many people are dealing with microphone sound issues on their 6P, however mine is a little bit different. My phone had "slight" liquid damage that was repaired by replacing a few parts and drying out. Everything on the phone has been working 100% except for an issue with the microphone.
Initially, there was no sound being recorded on the phone at all, and so I decided to try replacing the daughterboard on the bottom of the phone (where one of the microphones is). Immediately I had sound being recorded again!
However, I have found that I will record sound only from a few particular instances.
This is what works:
Phone call microphone (not speakerphone)
General voice recording apps
Google Now / Assistant
This is what doesn't work:
Camcorder microphone recording
Speakerphone microphone
Hangouts / Duo video calling (will work if i set to 'headset' speaker as opposed to speakerphone)
I am assuming it has something to do with the other microphones on the device, whether they are failing or it has something to do with the noise canceling effects.
Has anyone experienced an issue similar to this on this device (or other devices) and found a solution?
The only other option would be to replace the entire motherboard that contains the other microphone (which happens to be about a $200 part, with new EVERYTHING)
Short of removing and resoldering a replacement 'mic' on that board, is there any software solutions?
I love this phone dearly, and it's especially sad that I cannot even record video of my baby daughter with sound.
Any help would be appreciated!
Thanks,
Nathan
I don't know why so sudden my V20 got problem with it's mic.. There is even a bigger problem which is I don't even know what to be replaced now..
There is 2 situation here :
1 - When in call, with normal mode..everything is working fine but whenever i'm trying to put my phone to loudspeaker mode.. The people whose in call with me is claiming that there is a dead silence when i'm in loudspeaker mode..
Same goes when i'm in Whatsapp Videocall as example, i can hear them but they can't even hear me..
2 - When i'm doing recording with HD Voice Recorder app, the left channel won't even got anything recorded.. Only the right channel does the job..
Same goes with video recording, only right channel does the job while the left channel sound records nothing..
I'll be informed that V20 have 3 mic and it is obviously one at top and one at the bottom while another one is inside the phone nearby the earpiece if i'm not mistaken.. so now, i'll need help.. Which mic should i'll replace to get everything working again?
I'll believe my top mic is broken but which one? The one at the left before the earpiece or at the right next to earpiece? HELPPpPpppPpppPp
nevermind, got mine fixed.. just replace the new mic at the top and now i have back my fully functional V20 again..
i'll never know that phone is using a different mic for normal call mode and loudspeaker call mode.. Now i'm feeling like an idiot because everytime i'll do loudspeaker, i do scream at the bottom mic while it is using top mic ATM.. gosh
I just got mine and no one could hear me, i pushed a thumb tack in the bottom mic hole because it looked like a little plug or plastic was blocking it and and now it works fine, mine was a refurb phone
Bottom mic
My phone mics worked in speaker phone calls but not talking through the regular in-call mic. I had a repair man change the bottom mic today. He had to install 4 mics to get it and the one that worked was out if a Samsung phone! Cost me USD$60. Apparently my phone had water damage before I bought it used. That's annoying but I'm back in business!
I am in the same exact situation. Replaced the main loudspeaker, top two earpiece speakers and still my voice won't come through on the other end of a normal headset mode call. Only can speak through loudspeaker. What part must I replace? I'm thinking normal headset mode sound is received through the pinhole area next to the 3.5mm jack. What part do I replace?! It's getting personal now. I will fix this phone!!
Not counting the two earpiece speakers up top on the mainboard, and the large loudspeaker on the bottom what other speakers are there for me to replace?
